Motor bearings support the rotor and guide shaft rotation. Selection should consider bearing type, speed, radial and axial load, operating temperature, internal clearance, insulation, lubrication and sealing.

During assembly, control shaft and housing tolerances, roundness and pressing force. Use dedicated tools, apply force only to the ring with the interference fit, and keep chips, paint residue and other contaminants out of the bearing.

BNJ supplies matched solutions for induction, servo, stepper, brushless, three-phase and special motors, with options for precision, clearance, electrical insulation and grease.
