Deep groove and cylindrical roller bearings for motors, generators and alternators.
Most electric motors run on a deep groove ball bearing at each end of the rotor. Larger motors and generators use a cylindrical roller bearing at the drive end to carry belt or coupling load, with a deep groove bearing at the other end to locate the shaft.
Motor rewinding shops and maintenance teams need the right clearance and seal type. We stock open, ZZ and 2RS versions across the 6000, 6200 and 6300 series.
What we recommend
Bearing families for electric motors
Deep Groove Ball BearingsThe most widely used rolling-element bearing — carries radial and moderate axial loads, with a deep raceway that runs smooth and cool at high speed.6000, 6200, 6300, 6400
Cylindrical Roller BearingsLine contact across cylindrical rollers gives high radial capacity and stiffness under heavy load at speed.NU, NJ, NUP, NF
Angular Contact Ball BearingsRaceways set at an angle to the axis, so radial and axial load are carried at the same time — precise and rigid at high speed.3200, 3300, 7000, 7200
