2. REPLACEMENT - If replacement of bearings become necessary remember to clean o󰀨 the shaft, le smooth
grooves or set screw marks, and oil the shaft before slipping on the new bearing.
IF BEARING DOES NOT SLIDE ON EASILY, USE A SOFT METAL BAR TO
TAP AGAINST THE INNER RACE TO ASSEMBLE.
3. GENERAL - Set up a weekly check on all bearings to ensure they remain tightly bolted down, set screws
remain fastened securely and are properly lubricated.
V-BELT & SHEAVES
If provided on your drive package, V-Belt tension & sheave alignment are important for extended belt life. Read the
following list over for proper maintenance or installation.
1. Never pound sheaves on or o󰀨 a shaft. Make sure that the shaft diameter and sheave bore is properly sized.
If there are burrs caused by set screws or sharp edges on the keyway or keyseat, remove carefully with emery
cloth and/or le. Clean o󰀨 metal particles and dirt from the shaft and sheave before installation.
2. Sheaves must be in line with each other and installed on shafts which are parallel with each other.
3. DO NOT FORCE or use the drive to install a V-belt. Have driven components loose to install the belt(s).
4. With available take-up tighten belts enough to keep from slipping during operation. Ideal belt tension is the
lowest tension at which the belt will not slip under peak load conditions. The drive side of the belt(s) should be
straight across and the slack side should show a slight bow.
5. Do not place new belt(s) on worn sheaves.
6. If multiple belts are used, replace all belts with a new set or matched belts.
7. Do not use belt dressing on belt(s) which are slipping. Belt dressing will damage the belt and cause early
failure. Tighten belt(s) to proper tension, or if dirty, clean the belt(s) with a commercial rubber solvent.
CHECK V-BELTS AND SHEAVES ONLY WHEN CONVEYOR IS STOPPED!
