Free Wheels US

The US Series freewheels are not self centering. It is therefore required to place one or two bearings next to the freewheel so that the outer race can rotate centrally to the inner race.

US freewheels have ball bearings with the same dimensions as the 62 Series.

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 an interference fit on the J6 tolerance of the external diameter.

Shaft tolerance must be either h6 or j7; the tolerances for the seating must be either H7 or J6.

Before being put onto service, the freewheels must be lubricated with suitable lubricants following the instructions. Oil lubrication is essential when a high number of rotations in neutral is reached.
