Mounting
Mounting bearings with a cylindrical bore
Mounting bearings with a tapered bore
Bearings with a tapered bore are mounted with an interference fit, by using one of the following methods:
-
Feeling the clearance reduction by swivelling the outer ring (fig. 1)
- This method is valid for bearings with Normal radial clearance (not for sealed bearings).
- The clearance reduction in the bearing is sufficient when the outer ring can be turned easily, but a slight resistance is felt when it is swivelled out.
- Measuring the lock nut tightening angle (table 1)
- Measuring the axial drive-up (table 1)
-
Applying the SKF Drive-up Method (→ SKF Drive-up Method Program)
For bearings with d ≥ 50 mm, SKF recommends using the SKF Drive-up Method. This is a fast, reliable and safe method to determine the appropriate interference fit.
For additional information about these mounting methods, refer to Mounting bearings with a tapered bore, or the SKF bearing maintenance handbook.
