The UF Series freewheels are not self centering. It is therefore necessary to place one or two bearings next to the freewheel so that the outer race can rotate centrally to the inner race.
The torque forces are transmitted from the shaft to the inner race by means of a key and from the outer race to the seating by means of front pullers.
Shaft tolerance must be either h6 or j6; the tolerances for the seating must be either H7 or G7. When front pullers are not used, the seating tolerance should be K6.
Before being put onto service, the freewheels must be lubricated with suitable lubricant following the instructions. Oil lubrication is essential when a high number of rotations in neutral is reached.
