Illustrated here using a series FSL guide bushing with integrated clamping screws. The principle applies to all the listed series whereby the FD-series need an external initiation of clamping force (see examples).
The prinziple is shown in a simplified diagram with enlarged play.
Connection with assembly play between the housing, guide bushing and centre sleeve.
First phase of axial pre-stress: Mating play between housing and guide bushing eliminated, firm fit realized.
After further axial pre-stressing, the guide play between the guide bushing and sleeve is optimally adjusted.
