Tolerances and clearances
General bearing specifications
- Tolerances: Normal, P6, P5
- Internal clearance: table, drawing no
Bearing interfaces
- Seat tolerances for standard conditions
- Tolerances and resultant fit
Double row angular contact ball bearing, with wide and two-piece inner ring and relubrication feature, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement. The two-piece inner ring enables incorporation of more balls, resulting in higher load carrying capacity. The annular lubrication groove and holes in the outer ring facilitates relubication.
- Wide, two-piece inner ring
- Accommodate very high axial loads in both directions, radial loads, and tilting moments
- Relubrication feature
- Suitable where a stiff bearing arrangement is required
