Tractor bearings are mainly used in the field, the working environment is bad, and the continuous working time is long, which requires the bearings to be reliable in the use process, and work normally in the dusty environment,

 

Agricultural tractors are the work horses of the industry with drivetrain, engine, suspension and steering being key sub-systems Safety, availability and productivity are the underlying forces driving many of the industry trends, such as:

  • Automation, smart functionality and power management
  • Better efficiency which reduces frictional losses,

resulting in lower fuel costs

  • Increased power density and reliability
  • Standardization (consolidation of the powertrain)
  • Improved comfort and safety

The main types of bearings used by tractors are

— Single row tapered roller bearings

— Matched tapered roller bearings

— Inch tapered roller bearings

— Deep groove ball bearings

Inch Size Tapered Roller Bearings Size Chart

Inch tapered roller bearings refer to tapered roller bearings whose dimensions are measured in inches, originating from British and American countries.
Inch tapered roller bearings, like metric tapered roller bearings, consist of an inner ring, an outer ring and tapered rolling elements. Due to their designed geometry, tapered roller bearings can withstand combined loads (axial and radial). In addition, this design allows the rollers to continue to roll even if the rollers slip on the outer and inner race tracks.

Inch Tapered Roller Bearings are the most used roller bearings in the market, the materials can be chrome steel, carbon steel, stainless steel, ceramic materials and also ceramic coating which used in different applications, and OEM Service available with CoatMaster Bearings.

Inch size Tapered roller bearings refer to radial thrust rolling bearings in which the rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial loads mainly with radial loads. It is often used in pairs and installed in reverse. The inner and outer races can be installed separately. The radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the axial and radial combined loads, which are mainly axial loads. Generally, it is not used alone to support pure axial loads. When configured in pairs (installed with the same name opposite), it can bear pure radial loads.

The single-row tapered roller bearing’s ability to withstand axial load depends on the contact angle, that is, the outer ring raceway angle. The larger the angle, the greater the axial load capacity. The most used tapered roller bearings are single-row tapered roller bearings. In the front wheel hub of the car, a small double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.

Tapered Roller Bearings Size Chart

Tapered roller bearings are separable bearings, and both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into different structural types such as single-row, double-row and four-row tapered roller bearings according to the number of rows of rollers installed. Single row tapered roller bearings can withstand radial loads and axial loads in one direction. When the bearing is subjected to radial load, an axial component force will be generated, so when another bearing that can withstand axial force in the opposite direction is required to balance.

The ability of a single row tapered roller bearing to withstand axial loads depends on the contact angle, that is, the angle of the outer ring raceway. The larger the angle, the greater the axial load capacity. The most used tapered roller bearings are single row tapered roller bearings. In the front wheel hub of the car, a small-sized double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy-duty machines such as large cold and hot rolling mills.

Tapered roller bearings are mainly used to bear combined radial and axial loads mainly based on radial loads. Compared with angular contact ball bearings, the bearing capacity is large and the limit speed is low. Tapered roller bearings can withstand axial loads in one direction and can limit the axial displacement of the shaft or housing in one direction.

Tapered Roller Bearing have Metric size and inch size design,  and also carbon steel Tapered Roller Bearings, chrome steel tapered roller bearings, stainless steel tapered roller bearings, insulated tapered roller bearings, plastic tapered roller bearings, ceramic tapered roller bearings, high precision tapered roller bearings, high temperature tapered roller bearings.

What is a Bearing and its types?

The basic structure of the bearing: the inside of the bearing is generally composed of an inner ring, an outer ring, rolling elements and a cage. For sealed bearings, there are lubricants or greases, sealing or shielded.

Rolling bearing part:

The part where the rolling elements roll on the ring is called the raceway, and the raceway of the ball bearing is also called the raceway. The rolling elements are between the raceways of the inner ring and the outer ring. The rolling elements include steel balls, cylindrical rollers, needle rollers, tapered rollers and spherical rollers. The size and quantity of the rolling elements directly affect the speed and load ability of the bearing.

Rolling bearings have a variety of structural forms, each type of bearing has its own characteristics, their common advantages are:

  1. The starting friction is small, and the difference between the starting friction and the dynamic friction is also small.
  2. International dimensions and interchangeability, suitable for mass production
  3. The wear is less than that of ordinary sliding bearings, and the mechanical accuracy can be maintained for a long time.
  4. Easy to lubricate, less lubricant consumption and low maintenance cost
  5. It can be easily used at high or low temperature
  6. The surrounding components matched with the bearing have a simple structure, which is convenient for inspection and maintenance
  7. The rigidity of the bearing can be improved by applying preload
  8. Except for a few bearings (such as thrust bearings), general bearings can bear radial load and axial load at the same time

Bearings are classified according to the load direction or the nominal contact angle that they can bear.

Radial bearing — mainly used for rolling bearing bearing radial load, its contact angle ranges from 0 degrees to 45 degrees, and is divided into:

— Radial Contact Bearings — Radial Bearings with a Contact Angle of 0°

— Angular Contact Radial Bearings — Bearings with angular contact greater than 0° to 45°

Thrust bearing – mainly used for rolling bearings bearing axial load, according to the different contact angle is divided into

— Axial contact bearing Thrust bearing with a contact angle of 90 degrees

— Angular contact thrust bearing, the contact angle is greater than 45 degrees and less than 90 degrees

 

Bearings are classified according to the type of rolling elements

Ball bearing — the rolling elements are balls

Ball bearings are divided into deep groove ball bearings, self-aligning ball bearings, angular contact ball bearings, thrust ball bearings

Roller bearing — the rolling elements are rollers

Roller bearings are divided into

Cylindrical Roller Bearing–The rolling element is a cylindrical roller bearing, and the ratio of the length to the diameter of the cylindrical roller is less than or equal to 3,

Needle Roller Bearings — Bearings in which the rolling elements are needle rollers

Tapered Roller Bearings — Bearings whose rolling elements are tapered rollers

Spherical Roller Bearings — Bearings whose rolling elements are spherical rollers

 

Bearings are classified according to the self-aligning function

1) Self-aligning bearing — the raceway is spherical, which can adapt to the angular deviation and angular motion between the axis lines of the two raceways

2) Non-aligning bearings — bearings that can resist the angular deviation of the raceway axis

 

Bearings are classified according to the number of rolling elements row.

1) Single row bearing — bearing with one row of rolling elements

2) Double row bearing — bearing with two rows of rolling elements

3) Multi-row bearings — bearings with more than two rows, such as three-row, four-row bearings

 

Bearings are classified according to whether their parts can be separated or not

1) Separable bearing — bearing with separable parts

2) Non-separable bearing — a bearing in which the rings cannot be freely separated after the bearing is finally assembled

What are Tapered Roller Bearings?

 

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction. When the bearing is subjected to a radial load, an axial component will be generated, so when another bearing that can bear the axial force in the opposite direction is needed to be balanced.

Tapered roller bearings refer to radial thrust rolling bearings in which the rolling elements are tapered rollers. There are two kinds of small cone angle and large cone angle. The small cone angle mainly bears the combined radial and axial loads mainly with radial loads. It is often used in pairs and installed in reverse. The inner and outer races can be installed separately. The radial and axial clearance can be adjusted during installation and use; The large cone angle mainly bears the axial and radial combined loads, which are mainly axial loads. Generally, it is not used alone to support pure axial loads. When configured in pairs (installed with the same name opposite), it can bear pure radial loads.

The single-row tapered roller bearing’s ability to withstand axial load depends on the contact angle, that is, the outer ring raceway angle. The larger the angle, the greater the axial load capacity. The most used tapered roller bearings are single-row tapered roller bearings. In the front wheel hub of the car, a small double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.

The outer ring (or inner ring) of a double-row tapered roller bearing is a whole. The two small inner end faces of the inner ring (or outer ring) are close to each other, and there is a spacer in the middle. The clearance is adjusted by the thickness of the spacer. The thickness of the spacer can also be used to adjust the pre-interference of the double-row tapered roller bearing.

Four-row tapered roller bearings, the performance of this bearing is basically the same as double-row tapered roller bearings, but the radial load is greater than double-row tapered roller bearings, the limit speed is slightly lower, mainly used in heavy machinery.

 

The basic dimensions of China tapered roller bearings are listed in the dimensional data sheet,

Single-row tapered roller bearings:

Outer diameter range: 70mm ~ 1800mm

Width size range: 50mm ~ 460mm

 

Four-row tapered roller bearings:

Outer diameter size range: 200mm ~ 2000mm

Width size range: 150mm ~ 1150mm

Features and benefits of Tapered Roller Bearings

  • Low friction
    The optimized roller end design and surface finish on the flangepromote lubricant film formation, resulting in lower friction. This also reduces frictional heat and flange wear. In addition, the bearings can better maintain preload and run at reduced noise levels.
  • Long service life
    The crowned raceway profiles of basic design bearings and the logarithmic raceway profiles of Tapered Roller Bearings optimize the load distribution along the contact surfaces, reduce stress peaks at the roller ends, and reduce the sensitivity to misalignment and shaft deflection compared with conventional straight raceway profiles.
  • Enhanced operational reliability
    Optimized surface finish on the contact surfaces of the rollers and raceways supports the formation of a hydrodynamic lubricant film.
  • Consistency of roller profiles and sizes
    The rollers incorporated in CoatMastertapered roller bearings are manufactured to such close dimensional and geometrical tolerances that they are practically identical. This provides optimal load distribution, reduces noise and vibration, and enables preload to be set more accurately.
  • Rigid bearing application
    A single row tapered roller bearing is typically adjusted against a second tapered roller bearing. By applying a preload, a rigid bearing application can be achieved.
  • Running-in period with reduced temperature peaks
    Tapered roller bearings typically have a running-in period, during which a conventional design tapered roller bearing experiences a significant amount of friction, resulting in wear. This effect is noticed as a temperature spike. With CoatMaster tapered roller bearing designs, friction, frictional heat and wear are significantly reduced, provided the bearings are mounted and lubricated correctly.
  • Separable and interchangeable
    The inner ring with roller and cage assembly (cone) can be mounted separately from the outer ring (cup). Furthermore, the separable componentsare interchangeable. This facilitates mounting, dismounting and also maintenance inspection routines.

Spherical Roller Thrust Bearings are the same with spherical roller bearing, both of them are all self-aligning design, the raceway surface of the seat is a sphere which centered on a point and be coincident with the center axis of the bearing. and also the rollers of Spherical Roller Thrust Bearings are spherical, Therefore, it has self-aligning function, Less sensitive to concentricity and shaft deflection.

Thrust roller bearings are used to support axial and radial combined loads with axial loads, but radial loads must not exceed 55% of axial loads. Compared with other thrust roller bearings, this type of bearing has lower friction factor, higher speed and has self-aligning performance.

The roller of the 29000 type spherical roller thrust bearing is an asymmetrical spherical roller, which can reduce the relative sliding of the roller and the raceway during operation, and the roller has a long length , a large diameter, a large number of rollers, a high load capacity , and is usually oil lubricated . Individual low speed conditions can be lubricated with grease. When designing and selecting, it should be preferred;

Advantages of Spherical Roller Thrust Bearings

  • Higher performance bearingarrangements: more than double the rating life due to basic dynamic load ratings that are up to 30 % higher than before , higher static load safety factor due to basic static load ratings nearly 10 % higher, reduced wear due to improved surface quality and optimum lubricant film formation, higher speed capability due to reduced friction and operating temperature as well as special cage designs.

This is all made possible by longer rolling elements, optimised contact geometry and bearing kinematics, improved surfaces of the rolling contact partners for an optimised lubricant film, cages with better guidance of rollers and lubricant as well as closer dimensional and running tolerances.

What is the miniature thrust ball bearings?

Miniature Thrust Ball Bearings are only one kinds of Thrust Ball Bearings, But smaller size than normally thrust ball bearings, It’s a separable bearing with a contact angle of 90, which can be installed separately and can only bear the axial load. The limit speed of the miniature one-way thrust bearing is low, and the steel ball is squeezed to the outside of the raceway by centrifugal force, which is easy to be scratched, but it is not suitable for high-speed operation. One-way miniature thrust bearing can bear one-way axial load, and two-way bearing can bear two-way axial load. Miniature Thrust ball bearing with spherical seat ring has self-aligning performance, which can eliminate the influence of installation error.

Miniature thrust ball bearings are designed to withstand thrust loads during high-speed operation, and it consist of a washer-like ferrule with a ball-rolling raceway groove. Since the ferrule is in the form of a seat cushion, the thrust ball bearing is divided into two types: flat seat cushion type and self-aligning spherical seat cushion type. In addition, this bearing can withstand axial loads, but not radial loads.

Miniature thrust ball bearing structure: The material of the bearing retainer is divided into stainless steel and copper, and the material of the plane thrust ball bearing is bearing steel or stainless steel, which is divided into with groove and without groove.

The use of miniature thrust ball bearings: It is only suitable for parts that bear an axial load on one side and have a low speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. The shaft washer, seat washer and rolling elements of the bearing are separated and can be assembled and disassembled separately.

CoatMaster (China Bearing manufacturer, Germany Technology) can supply complete thrust bearings above mentioned, and we have stock of the thrust bearings list. OEM service available, any more details please contact with us anytime.

What is the Difference Between DE and NDE Bearing?

The floating end of the motor is also called the free end, which is relative to the fixed end; in general, the free end is selected at the non-drive end, but the motor load requirements are higher, and the axial matching size requirements with the load equipment are not very high. In this case, the free end will be selected as the drive end.

When the motor bearing support system is a double fulcrum and double bearing structure, the drive end is also used as the free end when the radial load is large. Especially for low-voltage, high-power and high-voltage motors, the cylindrical roller bearing at the free end can meet the radial load requirements. Large load requirements.

The rollers and raceways of cylindrical roller bearings are in line contact or under-line contact. The radial load capacity is large. It is more suitable for bearing heavy loads and impact loads. The inner ring or outer ring can be separated for easy installation and disassembly. This series of bearings has a small friction coefficient and is suitable for operating conditions with high speed and limit speed close to deep groove ball bearings. The more commonly used N-type and NU-type cylindrical roller bearings in motors can move axially between the inner and outer rings of the bearing, which can adapt to changes in the relative position of the shaft and the housing caused by thermal expansion or installation errors, and can be used as a free end support. However, the bearing has higher requirements for the machining of the shaft or the bearing chamber hole, and the relative deviation of the inner and outer ring axes after the bearing is installed must be strictly controlled to avoid contact stress concentration.

Insulated bearing for motor

Compared with the fixed-end bearing, in order to meet the axial displacement requirements of the rotor part during the operation of the motor, the axial clearance requirements of the outer ring of the bearing and the inner and outer cover of the bearing are different according to the selection of the bearing.

(1) When the free end adopts a bearing with separable inner and outer rings, for the two-bearing structure motor, the fixed end is selected at the non-driving end; the outer ring of the fixed end and the free end bearing and the inner and outer cover of the bearing are axially free of gaps Cooperate.

(2)When a non-separable bearing is used at the free end, that is, the relatively common two ends of small and medium-sized motors are ball bearing structures. In view of the impact on the installation accuracy of the drag equipment, the drive end is used as the fixed end, and the inner ring of the free end bearing should be limited There is a gap between the outer ring and the stop of the inner and outer cover of the bearing; at the same time, in order to ensure the axial matching displacement requirement during the operation of the motor, the radial matching between the outer ring of the bearing and the bearing chamber is not easy to be too tight. When there is no obvious difference between the fixed end and the free end of the motor, the matching relationship is in accordance with the principles in the previous issue of “Selection and Matching Relationship Requirements for Motor Fixed End Bearings”.

structure of insulated bearing in motor

Insulated bearings are mainly used in motor products. Its use is determined according to the power state of the motor. Normal grid power supply has no high-frequency voltage and current components. Generally, insulated bearings are not used. Only high-voltage motors and large motors such as 400 and above are used.

But now the variable frequency power supply power supply, because the quality of the power supply contains a lot of high-frequency components, which causes the motor shaft current to increase, so this issue should be considered for specifications above 400KW, and even the smaller specifications should also consider installing insulation Bearings according to the usage conditions. such as the main motors used in electric vehicles and electric rail locomotives, are generally about 100KW, and electrical insulated bearings must be used (or other insulation structures are used to ensure that the shaft current does not flow).

With the development of society and the progress of industrial technology, more and more equipment and application scenarios have stricter  requirements on the service life, noise level, and stability of bearings. As the most widely used power output device in industry, the motor is the most widely used power output device. Stability and service life play a particularly critical role in the application of equipment.

In the actual production and processing process, due to the actual integration of customers or production resources, especially the repair process of the motor, the substitution of bearings will inevitably occur. The more common one is the interchange of deep groove ball bearings and cylindrical roller bearings. , Especially when the radial load requirements are high, the deep groove ball bearing is often chosen to be replaced with a cylindrical roller bearing. If this situation exists, the conformity of the axial and radial matching relationship between the fixed end and the free end bearing must be considered .
