China Bearing used in oil & natural gas industry

With the development of offshore oil and natural gas, the demand for oil refining, ethylene and three major synthetic materials is gradually increasing. In this way, a large number of oil and gas pipeline gathering and transportation equipment and large-scale and efficient petrochemical equipment are needed, with emphasis on the development of large-scale oil exploration and drilling and production equipment in the desert and ocean. Therefore, the market demand for supporting and maintaining bearings, mechanical seals and packing static seals for petrochemical equipment will increase greatly every year.

It is suitable for the high temperature resistant sealed self-aligning roller bearing in the harsh environment. It is characterized by rubber seals on both sides to ensure the safe operation of bearing raceway in the dust-free environment and prevent the leakage of lubricating grease. It has the advantages of dust-proof, water-proof, high-temperature and high-pressure resistance, heavy load, etc., as well as open type and high-temperature resistant bearing suitable for specific applications. It can be used in -40 to +200 ℃ Under the condition of continuous safe operation, this is an attractive feature, which can not be replaced in many demanding applications.

The drilling equipment used in the oil industry includes mud pump, winch, top drive, crown block, etc. Working condition: heavy load, much sediment, strong corrosion, large impact vibration. The deep groove ball bearing, self-aligning roller bearing, cylindrical roller bearing, tapered roller bearing and thrust cylindrical roller bearing provided by coatmaster company increase the load capacity, improve the corrosion resistance and impact resistance performance, and extend the service life of the bearing by strengthening the design and manufacturing.Successful cases: our company’s four point contact ball bearing ar03-10, slr20 / 848 and thrust cylindrical roller bearing are used in an oil well in Shanghai, Xinjiang

Coatmaster China petroleum machinery bearing provides high-performance bearing solutions for petroleum machinery industry. In the field of petroleum machinery, the working conditions of the industry are harsh, high pressure, high temperature and various kinds of pollution seriously affect the normal operation of machinery. Coatmaster provides customers with safe and stable petroleum machinery bearing solutions for the industry environment, effectively improving energy efficiency and equipment working time Longer, less maintenance.

Coatmaster has more than 20 years of experience in rolling and sliding bearing design. It provides customers with a series of China bearing solutions specially designed for oilfield applications. Coatmaster provides us with unique capabilities using the latest analytical tools, including solid modeling, finite element analysis and proprietary bearing design programs. Using CMM enables coatmaster to accurately measure components to ensure the precision required for unique solutions to complex problems.

Mud pump and fracturing pump application

China Coatmaster heavy-duty needle roller bearing is specially designed for the position of crosshead bearing of mud pump. Coatmaster type provides higher load than single row roller. The series roller can get enough strength to guide the cage correctly. Compared with single row of rolling elements, the bearing capacity of double row of rolling elements is increased by more than 40%, and the fatigue life is increased by more than 200%.

Coatmaster offers a full range of large diameter, high quality cylindrical roller bearings, standard and custom designed, with an outside diameter of up to 60 inches (1500 mm). These bearings are made of high quality carburized or hardened steel. Coatmaster cylindrical roller bearing adopts bronze pin type cage and full roller type. Single row, double row, multi row, standard and customized bearings are available.

Coatmaster offers a wide range of single row and double row tapered roller bearings with an inside diameter of 11 inches (279 mm) or greater. Our highly specialized tapered roller bearing, inner ring, outer ring and roller are all carburized, so that the appearance is hard and the inside is soft, so that the bearing can bear heavy impact load and have better performance. The superior performance comes from the super precision of the rolling body, the raceway surface contacting with the rolling body and the unique raceway curve. The accuracy of tapered roller bearing reaches 2 kinds of standards, which is very suitable for the most demanding application requirements.

Rotary drive turntable application

Coatmaster produces highly specialized turntable bearings with a diameter of more than 60 inches (1524 mm), which are used in the design of turntable driven by oilfield equipment. Our turntable bearings are made of high-quality bearing steel and the most advanced manufacturing technology in the United States, and have achieved unparalleled performance in the most demanding environment. At the same time, many standard turret bearings are in stock and ready for shipment.


Top drive, swivel and hook applications

Coatmaster produces a range of heavy-duty tapered roller thrust bearings with an inside diameter of 4 inches (101 mm) to 16 inches (406 mm). Coatmaster heavy-duty tapered roller thrust bearing is specially designed for use in harsh environments. These bearings are equipped with carburized inner and outer rings and machined brass cages. The large end face of the roller is processed into a spherical shape, which is matched with the corresponding inner and outer rings. Under the guidance of the cage, the lubrication effect is improved. These bearings are well suited for extreme high thrust and shock loads. When the speed is not high and it needs to bear super-high load, we have full roller tapered roller bearing to meet your maximum load application requirements.

Coatmaster supplies a wide range of standard cylindrical roller thrust bearings from 3.5 “(89 mm) to 24” (610 mm) in outside diameter. These high load cylindrical roller thrust bearings are ideal for heavy and medium speed applications. Coatmaster cylindrical roller thrust bearing consists of two hardened and finely ground bearing steel inner and outer rings, equipped with machined brass cage, so that the roller can normally operate in each cage unit. The performance of the bearing will be enhanced according to the use of multiple rollers and different lengths in the same cage unit. Rollers placed in a staggered position create overlapping raceway grooves to prevent wear and thus extend bearing life

Pipeline treatment and application of CT injector

Coatmaster has a complete set of CAM Follower roller bearing production line, which is very suitable for the application of large impact load, high rotation speed and corrosive application environment. With a long history of innovation, coatmaster has ushered in a new era of roller bearing, which provides a maintenance free bearing in the most robust applications with higher load, higher speed.

The same innovation also comes from coatmaster CAM Follower roller bearing, which allows customers to easily and quickly lubricate the bearing where it is difficult to reach frequently or hard to touch the roller head.

Coatmaster CAM Follower roller bearings are manufactured to strict specifications and can be supplied with corrosion resistant coatings and coatings when required.

Coatmaster special injection head bearing uses our technology to improve the dynamic and static load bearing of the bearing. The carburizing treatment of the inner and outer rings makes the bearing more durable when impacted. Grease port is used in the center of end face to facilitate grease lubrication to each raceway surface.

Offshore equipment application

Coatmaster self-lubricating bearings are widely used in offshore equipment, where environmental conditions are serious and external lubrication is impractical. The bearings are made of corrosion-resistant alloy and solid lubricant developed for seawater utilization. Bearing provides reliable performance, long service life, no need to supplement lubrication, and free maintenance.

Coatmaster is capable of manufacturing slewing rings with a design range from 24 inch (610 mm) to 169 inch (4293 mm) diameter. If necessary, the slewing ring bearing can be matched with the internal and external transmission devices. The types of slewing support are single row, double row ball, single row roller and multi row roller.
