Calculation of shim required
Thickness of shim can be calculated with the dimensions determined.
Example :
Cover dimension :
Housing dimension : Dim. F measured on housing
Bearing dimension : Dim. B measured on bearing under preloading force
Constant :
Add shims according to thickness X.

Prepare the shim thickness determined
under chapter (2) above "Calculation of
shim required" by means of the differently
thick shims.
Put shim(s) (item 1) and bearing outer
ring (item 2) into the bearing seat.
By means of striking mandrel "S" drive
shim(s) and bearing outer ring (item 1)
into the bearing seat of the housing cover
until contact is obtained.
