MOUNT:
1. Check all cap screws are freed.
2. Tighten cap screws in a star pattern as seen above. Repeat.
3. When using a torque wrench, first tighten each cap screw to 50 percent of the specified torque value, and then tighten them again to the full 100 percent torque value. Make sure to use a star pattern both times.
Note: The adapter sleeve needs to be pulled to lock and we use the left-hand cap screws to turn clockwise to pull. When you tighten the cap screws, the gap between two nuts gets bigger and the adapter sleeve is moving towards the outside. The outside nut should move parallel to the inside nut to avoid the cap screws twisting and getting damaged. This is why the cap screws are tightened in a star pattern and repeated. You may need to repeat this several times to tighten all the cap screws perfectly, this is a very standard way as seen with automobile wheels.
DISMOUNT:
1. Loosen all cap screws unitl they are freed.
2. Turn cap screws counterclockwise in a star pattern and repeat until dismounted.
Note: When you want to unlock CROSSLOC™, loosening and turning counterclockwise is needed. They are the same left rotation but turning counterclockwise does not loosen. Loosen all cap screws to be freed first. Then you need to push the outside nut to release the adapter sleeve from the inner ring. Turn the cap screws counterclockwise in a star pattern and repeat until dismounted. It’s same as locking and the outside nut should move parallelly.
Recommended Shaft Tolerance : -0.006 in. / -0.152 mm
If the shaft diameter is smaller than the specified tolerance above, try rotating the CROSSLOC™ nut clockwise to reduce the sleeve inner diameter and adjust the fit.
FIX TO EXPANSION
When your application needs to be able to accommodate thermal expansion of the shafting, use only one fixed bearing on each shaft.
To convert the unit to an expansion type, remove the upper half of the housing and take out the locating ring.
The tightening torque for the split housing cap bolts is 480 ft-lbs (650 Nm). After tightening, rotate the bearing by hand to ensure it turns freely without resistance.
