100 | Applying the
recommended values prevents the inner ring from creeping, but does not ensure correct radial internal clearance in operation. Additional influences from the bearing housing fit and temperature differences between the inner and outer rings must be considered carefully when selecting the bearing radial internal clearance class (Selecting internal clearance or preload). |

- 1) Not valid for the SKF Drive-up Method.
- 2) The listed values are valid only for solid steel shafts and general applications. They are to be used as guideline values only, as it is difficult to establish an exact starting position. Also, the axial drive-up, s, differs slightly between the different bearings series.
- 3) Valid only where SKF adapter sleeve assemblies or lock nuts with thread pitches in accordance with ISO 2982-1 or ISO 2982-2, respectively, are used.
