Electrically Insulated Bearing 6312 M/C4VL0241 Insocoat Bearing 60×130×31mm Used In Railway Industry
Electrically Insulated Bearing 6312 M/C4VL0241 is Deep Groove Ball Bearing design. its dimension is 60×130×31mm , it has the same dimension and the same design with normal chrome steel 6312 bearing . but the most different is 6312 M/C4VL0241 bearing with Aluminium Oxide Coating . the coating can Electrical Resistance Voltages up to 3000 V DC.
A much more economical solution is to provide for the use of Electrically Insulated Bearing 6312 M/C4VL0241 during the planning stage. This reduces maintenance and repair costs, and increases machine availability – all of which means greater value for the customer.
In most cases, it is sufficient to interrupt the electric circuit between the housing and shaft, in order to mount Electrically Insulated Bearing 6312 M/C4VL0241 at one or both bearing locations, depending on the application .

Electric Insulated bearing 6312 M/C4VL0241 have an electrically insulating coat on the outer ring(suffix VL0241) or on the inner ring(suffix VL2071), respectively. insulated bearing are widely used in Electric Motors , generator , Alternator . there are 100μm thick coating on the surface of inner or outer ring, the insocoat bearing can bear voltages up to 1000V DC,insulated & insocoat bearing can keep away from moisture and humidity , it can carry radial and axial loads in both directions.
Electrically Insulated Bearing 6312 M/C4VL0241 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 .
