Electrically Insulated Bearing 6012 M/C4VL0241 Bearing 60×95×18mm Used In Locomotive And EMU Powertrain System
Electrically Insulated Bearing 6012 M/C4VL0241 is Deep Groove Ball Bearing design. its dimension is 60×95×18mm, it has the same dimension and the same design with normal chrome steel 6012 bearing. but the most different is 6012 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 6012 M/C4VL0241 Bearing 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 at one or both bearing locations, depending on the application.
Generally, Electrically Insulated Bearing 6012 M/C4VL0241 Bearing (ceramic-coated ) exhibit significantly higher resistance to electrical current than standard bearings.
