Self-aligning Ball Bearing

Self-aligning ball bearings have two rows of balls and a common sphered raceway in the outer ring and this feature gives the bearing its self-aligning property which permits a minor angular displacement of the shaft relative to the housing. These bearings are particularly suitable for applications where misalignment can arise from errors in mounting or shaft deflection. A variety of designs are available with cylindrical and taper bores, with seals and adapter sleeves and extended inner rings.

Features and benefits

• Accommodate static and dynamic misalignment
  The bearings are self-aligning like spherical roller bearings or CARB bearings.
• Excellent high-speed performance
  Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
• Minimum maintenance
  Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
• Low friction
  Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.
• Excellent light load performance
  Self-aligning ball bearings have low minimum load requirements.
• Low noise
  Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.
