Tolerances and clearances
General bearing specifications
- Tolerances, radial clearance and recommended fits:
- Endurakote bearings: Class 1, Class 1, Class 3, Class 4
- bearings: Class 1
- other bearings: Class 1, Class 1, Class 3, Class 4, Class 6
- Materials
Four-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 available with or inch main dimensions. Depending on the design and series the bearings can be provided with chemical and corrosion resistance.
- Accommodate radial, axial and moment loads simultaneously
- Require considerably less axial space than two angular contact ball bearings
- Thin cross section
- Lightweight
- Low friction
- High stiffness
- High running accuracy
