(Only applies to P1 plain bearings)
KS PERMAGLIDE® plain bearings are ready to install on delivery, and should only be calibrated if a bearing clearance with a narrower tolerance cannot otherwise be reached.
Calibration considerably shortens the service life of KS PERMAGLIDE® P1 bushes (see Tab. 1).
Figure 1 shows calibration using a mandrel. Table 1 contains standard values for the diameter of the calibrating mandrel dK. Precise values can only be ascertained through tests.
The bearing clearance tolerance can be reduced through the following measures, which do not adversely affect service life:
- Narrower tolerances for housing bore
- Narrower shaft tolerances
