The Boca Bearing Company 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 equipment is often relied upon for mission critical situations and can be very costly to repair.
The elements 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.
