Electric Insulated Deep Groove Ball Bearing 6319/C3 provide a bearing function and electrical insulation, virtually eliminates premature bearing failure caused by stray electric currents, electrical insulated bearing can reduce the number of failures and improve the machine uptime, reduce the cost of maintenance.

Electric Insulated Deep Groove Ball Bearing 6319/C3 consist of one inner ring, one outer ring with Aluminuim Oxide Coating, and one piece of machined brass cage, steel balls, Its dimension are the same with normal chrome steel 6319/C3 Deep Groove Ball Bearing.

China electrically insulated bearing 6319/C3 are widely used in many kinds of industry, Motors, generators and related equipment are in danger when current passes through the bearings. This not only damages the contact surfaces of the rolling elements and raceways in the bearing (electrical corrosion), but also quickly degrades the grease. Another additional risk comes from high-frequency currents in motors and generators, which can form a loop through the parasitic capacitance inherent in the device. Increased risk of damage if frequency converter is used.

CoatMaster Electrically insulated bearings:

— Designed to prevent current from flowing through the bearing

— The outer surface of their inner or outer ring is coated with an insulated alumina layer, and a sophisticated plasma spray process is applied to obtain an excellent quality finish.

— A very cost-effective solution compared to other insulation methods

Characteristics of CoatMaster insulated bearings

  1. Resistant to electrical corrosion

By integrating insulation performance into the bearing, electrically insulated bearings can improve reliability and increase machine uptime by actually eliminating the problem of electrical corrosion

  1. High resistance

Alumina coating has a minimum resistance of 200MΩ and can withstand voltages up to 3000 V DC

3.Stable electrical performance

Plasma spraying is usually hygroscopic and therefore easily susceptible to condensation and infiltration. To prevent this effect, Electrically insulated bearings are treated with a unique sealant.

Electrically Insulated Rolling Bearing as a Preventive Measure
As a rule, it is very difficult to eliminate the causes of bearing voltages that are induced by the motor. Nevertheless, it is possible to avoid damage to the bearing, if the flow of current can either be prevented or at least significantly reduced. Many types of Electrically Insulated Bearing are available today for this very purpose.

The railway industry never stands still and improvements and performance are developed daily. Together with our customers, we are always aware of the latest trends in the market place and we are committed to staying completely up-to-date to make sure that the very latest developments are integrated into new products.

Drive systems, such as gearboxes and traction motors for railway trains, have to be powerful, environmentally friendly, cost-effective and require very low needs for maintenance. These requirements are much more stringent than those in many other industries, because of the weight of railway vehicles and the long service intervals for high speed trains.
