Insulated Bearing 6334 M/C3VL2071 Inner Ring Coating

Bearings in electric motors and generators must support the rotor radially and locate it axially in relation to the stator. The typical bearing system consists of a locating and a non locating bearing. In most medium and large motors and generators, the locating bearing is a deep groove ball bearing, while the non-locating bearing can be a deep groove ball bearing, an N or NU design cylindrical roller bearing or a CARB toroidal roller bearing. Smaller motors, fitted with two deep groove ball bearings mounted on a short shaft, often have a cross-locating bearing system.

Ball Bearings for Generators and Electric Motors

The new series of ball bearings bears the suffix “-G” (e. g. 6330) and features the same outside dimensions as standard deep groove ball bearings according to DIN 620. The design has been customized for use in generators and electric motors. Three vari- ants are available depending on the application:


Standard steel variant (e. g. 6330)

• All components made from high-quality bearing steel

• Easier relubrication thanks to the sheet steel cage

• Reduced noise generation due to optimized cage pocket geometry


China EASIER Insulated bearings


Features of insulated bearings

1. High insulation properties

To prevent electric corrosion in bearings, a highly productive aluminum ceramic coating material is used to coat the outer ring, and by combining optimized additives, insulation performance is improved by about tenfold.

2. Improved durability

· Optimizing bearing elements improves film impact resistance by a factor of 3x.

· Optimized ceramic coating materials makes for excellent heat dissipation.
