ISSUE DATE: 8/07/2017

Torquing of Set-screws

1. Torque screw “A” to 1/2 recommended torque.
2. Torque screw “B” to full min. recommended

value.

3. Torque screw “A” to full recommended value.

After proper installation of the bearing(s),

run the unit for 10 to 15 minutes. Shut

the unit down and lock it out. Check for

proper engagement of locking collar and

tightness of set screw(s).

When replacing split bearings, refer to manufacturer’s

instruction provided with the bearing.

It is extremely

important to ensure that proper radial clearances are

observed between the roller bearings and outer face.

Failure to make proper adjustments will cause prema-

ture failure of the bearing.
