Tolerances and clearances
General bearing specifications
- Tolerances: Normal, P6, P5, ISO - F6 (Fw)
- Radial internal clearance: table
Design considerations
- Housing tolerances: table
- Shaft tolerances: Operating clearance
Single row needle roller bearings without an inner ring consist of an outer ring with a needle roller and cage assembly. They are an excellent choice for compact bearing arrangements in applications where hardened and ground raceways can be provided on the shaft. The outer ring includes two non-separable closure rings that act as flanges to guide the bearing axially.
- High radial load carrying capacity
- High stiffness
- Low cross-sectional height
- Accommodate axial displacement in both directions
