Quick How-to Guide for Adjusting a Hevi-Rail Combined Bearing

May 06, 2011 - Rockford, IL  -  Posted by Dave Walden

Hevi-Rail bearings are heavy duty roller bearings that provide extremely high load capacities for material handling and other applications.  In particular, the HVBEA series bearings provide a good way to deal with axial clearances in the system.  Below are the steps to adjust the eccentric portion of the bearing to reduce any axial play.

1. Remove all of the Allen head screws from the face plate.
2. Apply even pressure, pulling up on the outside raceway while pushing down on the eccentric bearing, to separate the two bearings.
3. Measure from the flat casing surface to the highest point of the eccentric bearing.
4. Rotate the eccentric bearing around the off-set axis to change the height of the bearing from the flat casing surface.
5. Re-measure and adjust until the distance needed is reached.
6. Re-assemble the bearing and tighten all of the screws back into the face plate.
