Clamp Tightening Procedure
The tightening procedure and torque requirement is critical in keeping in keeping the clamp tight and also has a
significant affect on the bearing life of the axles with internal bearings.
Clamp Tightening Procedure:
1. Check axle and clamp for burrs on mating surfaces.
2. Remove end play between wheels by sliding wheels
toward the fixed end of the axle.
3. Position clamp snugly against the end wheel.
4. Tighten the U-bolt evenly to 57 ft/lbs (U-bolt must be
tightened first.) See Figure 4-2.
5. Tighten set screws to 37 ft/lbs (Some clamps do not
have set screws.)
6. If the axle has an internal bearing, check that it turns
freely. You should be able to turn the bearing with
your fingers. If rotation is jerky, loosen set screws and
U-bolt until bearing turns smoothly. It may be
necessary to loosen and reposition clamp.
The torque requirement is recommended for axles without internal bearings, but is not critical.
Axle Installation:
When installing a roller axle with an internal bearing onto a support bracket, it is important to keep the roller axle
aligned as straight as possible to the installed position. If the roller assembly is significantly out of line when sliding it
unto a fixed support, the inner race of the bearing may crack and cause premature bearing failure.
