Electrically Insulated Bearing 6212 M/C4VL0241 is Deep Groove Ball Bearing design. its dimension is 60×110×22mm, it has the same dimension and the same design with normal chrome steel 6212 bearing. but the most different is 6212M/C4VL0241 bearing with Aluminium Oxide Coating. the coating can Electrical Resistance Voltages up to 3000 V DC.
Electrically Insulated Bearing 6212 M/C4VL0241 Bearing are not only Electrically Insulated deep groove ball Bearing, but also Electrically Insulated Cylindrical Roller Bearing, Electrically Insulated Tapered Roller Bearing, Electrically Thrust Roller Bearing and the other type Normal or Non-Standard Electrically Insulated Rolling Bearings. They are the same dimension, same cage, same elements and the other data with normal chrome steel rolling bearing, just the different coating on the surface of the inner ring or outer ring of the Rolling Bearing.
Electrically Insulated 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.
Benefits of Electrically Insulated Bearing 6315 M/C4HVL0241 Bearing
• two functions in one solution:
– a bearing function
– electrical insulation
• virtually eliminates premature bearing failures caused by stray electric currents
• increases machine uptime
• reduces maintenance costs
• provides an economical solution when compared with other insulation solutions
• global availability.
Electric Insulated bearing used in:
• wheelsets and traction motors
(rail vehicles)
• DC and AC motors (drivetrains)
• generators (wind power)
