Motor Bearings

The purpose of a bearing in an electric motor is to support and locate the rotor, to keep the air gap small and consistent and transfer the loads from the shaft to the motor. RCB BEARING will be happy cooperate with you.

The purpose of a bearing in an electric motor is to support and locate the rotor, to keep the air gap small and consistent and transfer the loads from the shaft to the motor. The bearings should be able to operate at low and high speeds whilst minimizing frictional loses. At the same time the bearing must be economic and require absolutely minimal maintenance (if any).
 
RCB Bearings has recently expanded inventory to include Electric Motor Quality (EMQ) bearings and Ceramic Coated Insulated High Voltage bearings. The electric motor and electric power generation industries are constantly seeking increased efficiency and longer up-times. This electrical machine is often relied upon for mission critical situations and can be very costly to repair.

The factors that result in bearing noise are surface finish, ball grade, ring roundness, cage design, cage quality and absolute manufacturing repeatability. Electric Motor Quality (EMQ) bearings have extremely low noise levels so they can be used in electric motors or other noise critical applications. EMQ bearings are available in 3 different noise levels ZV2 (low noise), ZV3 (very low noise) and ZV4 (extra low noise.) Typically EMQ bearings are supplied in chrome steel 52100 with standard or C3 radial play and they can handle heavy radial loads with moderate axial loads.
