Drawing legend:
d = inner diameter D = outer diameter W = width r = edge radius T = torque n = rotation speed C = load capacity
The specified nominal torque is based on sufficient stiffness of mating parts.
Rotation speed n for series FKN (without seals) = assembly unit's inherent speed
Rotation speed n for series FKN 2RS (with seals) = speed difference of mating parts.

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.
Series FKN 6203-RS has an RS seal on one side only (RS Seal on the freewheel side).
All specifications for series FKN 2RS (with seals) and series FKN (without seals)
