Roller Axle Wheels
After an initial run of 5-10 hours, check the Roller Axle
Assemblies to insure that the wheels are tight to one
another. Allow just enough looseness so each wheel will
turn by itself. If not slide the wheels tight together and
adjust the Axle Clamps. Thereafter check assemblies
every 50-100 hours.
Clamp Tightening Procedure:
The tightening procedure and torque requirement is
critical in keeping the clamp tight.
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
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.
