Dismounting

Because the degree of the interference fit is relatively low for super-precision bearings, lower ring dismounting forces are needed compared to other rolling bearings.

Dismounting forces

For bearings in spindle applications, the dismounting forces can be estimated as follows:
  • dismounting a set of three angular contact ball bearings from the housing → F ~ 0,02 D
  • dismounting a set of three angular contact ball bearings from the shaft → F ~ 0,07 d
  • dismounting a cylindrical roller bearing from its tapered seat → F ~ 0,3 d

where

F=dismounting force [kN]
D=bearing outside diameter [mm]
d=bearing bore diameter [mm]
