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.
