Electrically Insulated Cylindrical Roller Bearing NU326 ECM/C4VA301 with Outer Ring Coated For Drive Systems of Railway Vehicles

Electric Insulated Cylindrical Roller Bearing NU326 ECM/C4VA301 provide a bearing function and electrical insulation, virtually eliminates premature bearing failure caused by stray electric currents, electrical insulated bearing can reduce the number of failures and improve the machine uptime, reduce the cost of maintenance.

Electric Insulated Cylindrical Roller Bearing NU326 ECM/C4VA301 consist of one inner ring, one outer ring with Aluminuim Oxide Coating, and one piece of machined brass cage, steel balls, Its dimension are the same with normal chrome steel NU326 ECM/C4 Cylindrical Roller Bearing.

Electrically Insulated 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.

A much more economical solution is to provide for the use of Electrically Insulated Bearing NU326 ECM/C4VA301 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.
