Electrically Insulated Bearing 6315-M-J20AA is Deep Groove Ball Bearing design. its dimension is 75×160×37mm, it has the same dimension and the same design with normal chrome steel 6315 M bearing. but the most different is 6315-M-J20AA bearing with Aluminium Oxide Coating. the coating can Electrical Resistance Voltages up to 3000 V DC. This kind of bearing are widely used in high quality demand application like traction motor.
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.

Ball Bearings for Generators and Electric Motors
The new series of ball bearings bears the suffix “-G” (e. g. 6330-G) 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-G)
• 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
Variant with current-insulating coating (e. g. 6330-G-J20GA):
• Inner or outer ring coated with Schaeffler’s INSUTECT (ceramic) coating
• Secure protection against disruptive voltages of 1,000 V DC to 5,000 V DC through the use of different coating thicknesses
• INSUTECT coating provides outstanding protection even in high levels of humidity
Variant with current-insulating ceramic balls (e. g. HC6330-G):
• Rolling elements made from high-quality ceramic material provide optimum insula- tion protection
• Longer bearing and grease operating life
• Ceramic balls ensure optimum emergency running characteristics
