Complete units FP/FPD/FN/FND 400
outer ring with press fit hub D = H6
inner ring with press fit (FP/FPD) shaft d = h5
inner ring with keyway (FN/FND) shaft d = js6 (k5)
Keyway specifications according to DIN 6885, Bl.1 (P9) with back clearance.
Machine parts, in which Free-wheel Clutches are pressed in or on, can be of ferrous or nonferrous material. If you are considering using nonferrous material please contact our technical staff first.
For pressed in or on Free-wheel Clutch rings no retainers are necessary for axial or radial security. The inner rings with keyway (type FN and FND) have to be secured in the axial direction only, if the pressed on outer machine part (gear or lever) is not axially secured. When mounting Free-wheel Clutches with bearings do not apply pressure to bearing balls.
After installation a radial clearance between C2 and C5 will be reached. To create a clearance of C2 you should produce your shaft at the highest point and your housing at the lowest point of the allowed tolerances.
Attention: Please take care for total cleaning of Free-wheel rings and mating parts before press fitting (no grease particles left in the press fit area).
Lubrication: Series type FPD 400 and FND 400 are shipped oil lubricated for lifetime. Series type FN 400 and FP 400 are shipped rust protected – not lubricated.
