Four-point contact ball bearing with locating slots

Four-point contact ball bearings with locating slots can accommodate high axial loads in both directions and small radial loads.

They can operate at very high speeds and are more suitable than deep groove ball bearings for supporting large axial forces. The outer ring, with ball and cage assembly, can be mounted separately from the two inner ring halves. The locating slots can be used to prevent the outer ring from rotating.

  • High-speed capability
  • Accommodate high axial loads in both directions and small radial loads
  • Require considerably less axial space than double row angular contact ball bearings
  • The locating slots can be used to prevent the outer ring from rotating
