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.

Dimensions and Capacities

Drawing legend:

d = inner diameter D = outer diameter W = width r = edge radius T = torque n = rotation speed C = load capacity

All specifications for series FK 2RS (with seals) and series FK (without seals)

The specified nominal torque is based on sufficient stiffness of mating parts .

Rotation speed n for series FK (without seals) = assembly unit's inherent speed

Rotation speed n for series FK 2RS (with seals) = speed difference of mating parts.

The back driving torque is restrained by the torque arm. The torque arm must not be clamped into position. It must have 0.5 inch play in the axial and in the radial direction.

FRHM backstops are supplied for a clearance fit. Set screws on the inner ring are provided for axial retention, shaft collars are not required.
