Installation
Installation tolerances
Shaft n6; hub N7
 
Mating parts
Hardening and grinding of the mating parts is not necessary. Thoroughly clean (grease free) the mating parts in the vicinity of the freewheel clutch as well as the freewheel clutch's rings before making the press fit.
 
Bearing
The freewheel clutch includes ball and roller bearings. Additional external bearing support is not necessary.
 
Press fit pressure                   
Press fit pressure must not be applied to the balls.
 
Clamping direction
The arrow on the inner ring designates the inner ring's clamping direction.
 
Seals*
The RS Seals reliably seal out grease and dust but are not suitable
to protect against permanent higher liquid levels.
