Ultra-Slim thin section four-point contact ball bearingFour-point contact ball bearings can accommodate radial, axial and moment loads simultaneously. One bearing series is based on a single cross section which remains constant as the bore diameter increases, leading to significant space and weight savings. The bearings are not recommended for applications having continuous rotation.
- Accommodate radial, axial and moment loads simultaneously
- Require considerably less axial space than two angular contact ball bearings
- Extremely thin cross section
- Lightweight
- Chemical and corrosion resistance
- Low friction
- High stiffness
- High running accuracy
