Self-Aligning Ball Bearings

NSK’s comprehensive range of angular contact ball bearings has been designed to meet the ever-evolving requirements of equipment manufacturers.
Angular contact ball bearings feature a contact angle that sustains significant axial loads in one direction at the same time as radial loads.
Since an axial component is generated when radial load is applied, these bearings are typically used in pairs or multi-bearing sets.

Features

• Correct misalignment
  Self-aligning ball bearings have a spherical raceway in the outer ring with a center of curvature matched with the bearing center. This allows the inner ring, balls, and cage to rotate freely around the bearing center, maintaining alignment. Permissible dynamic misalignment is about 0.07 to 0.12 radian (4 to 7 degrees) under normal loads.
• Ideal for difficult mountings
  Self-aligning ball bearings suit applications where shaft bending occurs and where it is difficult to align the shaft and housing (transmission shafts, etc.)

Applications

• Gearboxes/speed reducers
