MOUNT:

1. Make sure there is no load on the bearing and all cap screws are loose.

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 must be pulled outward to lock the bearing. CX CROSSLOC™ uses left-hand threaded cap screws, which are turned clockwise to pull the sleeve outward. As the cap screws are tightened, the gap between the two nuts increases and the adapter sleeve moves outward. The outer nut must remain parallel to the inner nut to prevent the cap screws from twisting or being damaged. This is why the cap screws must be tightened repeatedly in a star pattern. Several passes may be required to tighten all cap screws evenly.

DISMOUNT:

1. Make sure there is no load on the bearing, then loosen all cap screws until they are free.

2. Turn the cap screws counterclockwise in a star pattern. Repeat until the bearing is released.

Note: To unlock CROSSLOC™, two steps are required: loosening and then turning the cap screws counterclockwise. Although both involve counterclockwise rotation, they serve different purposes. First, loosen all cap screws until they are free. Then continue turning the cap screws counterclockwise to push the outer nut and release the adapter sleeve from the inner ring. Turn the cap screws in a star pattern and repeat until the bearing is released. As with locking, make sure the outer nut moves evenly and remains parallel.

Recommended Shaft Tolerance : -0.004 in. / -0.102 mm

When the shaft is smaller than above, you can try below.

1. Loosen the CROSSLOC™ two nut locking system and take off from the unit. (Take care not to change the clearance between the nuts.)

2. Push the adapter sleeve from the back of bearing by hitting with the driver and hammer.

3. Make sure the shaft can slide through the bore of bearing easily.

4. Put the CROSSLOC™ two nut locking system back on the bearing. When two nut system won't rotate any further, hit with the driver and hammer to turn and tighten.

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.
By simply moving a snap ring on the back of the unit the bearing can easily be converted from non-expansion to expansion or vice versa.
