Specific installation instructions for freewheel clutch insert elements with rings

INSTALLATION INSTRUCTIONS FOR THE FR AND FRN SERIES

  • Installation tolerances 

Shaft h5; hub H6 (FR) /

shaft js6 (k5); hub H6 (FRN)

 

  • Constraints

The freewheel clutch insert element requires axial constraints on both sides.

 

  • Mating parts

Hardening and grinding of the mating parts are 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

Freewheel clutch insert elements are not self-centering. External bearing support to define the gap between mating parts (inner and outer rings) is necessary.
