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 with seals or shields 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 integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out. The bearings are available with and inch boundary dimensions.
- Accommodate radial, axial and moment loads simultaneously
- Require considerably less axial space than two angular contact ball bearings
- Integral sealing prolongs bearing service life
- Thin cross section
- Lightweight
- Low friction
- High stiffness
- High running accuracy
