Tolerances and clearances
General bearing specifications
- Tolerances
Single direction tapered roller thrust bearings are designed to accommodate heavy axial loads and peak loads in one direction. The bearings provide a high degree of stiffness and require little axial space. NR manufactures tapered roller thrust bearings in several different basic and application-specific designs and variants.
- High axial load carrying capacity
- High stiffness
- Long service life
- Require little axial space
- Separable design
