Lubrication

General
Lubrication is an important part of preventive maintenance.
The service life of bushings, bearings and bearing pins can be
extended considerably if the machine is lubricated in a cor-
rect way. A Lubrication chart makes Lubrication work easier
and reduces the risk of forgetting greasing points.
Lubrication has two main purposes:
– To supply grease to the bearing, to reduce wear between the
pin and the bearing.
– To replace old, dirty grease. The grease stored inside the outer
seal collects dirt and water and prevents them from penetrating
into the bearing.
IMPORTANT
Wipe off grease nipples and the grease gun before greasing,
to avoid introducing sand and dirt particles with the grease.
