Servicing the Caster Wheels
and Bearings
The caster wheels rotate on a roller bearing supported by a
spanner bushing. If the bearing is kept well lubricated, wear
will be minimal. Failure to keep the bearing well lubricated
will cause rapid wear. A wobbly caster wheel usually indicates
a worn bearing.
