Figure 4. Friction at rolling contact and guide flanges
was carried out on a test setup to deter-
mine the actual operating conditions.
The result was a ma ximum bearing
temperature of only 130 degrees C. By
selecting a grease that was suitable for
this temperature range and by maxi-
mizing the amount of grease in the
bearing, the specified service life could
then be achieved.
Improving Bearing
Reliability
As can be seen from these examples,
the operational reliability and durability
of bearings can be significantly improved
by correctly assessing and adjusting lubri-
cation. is also helps to reduce initial
costs and avoid other costs associated with
premature bearing failures. As a general
rule, the sooner the issue of lubrication is
addressed, the easier and more cost effec-
tively potential problems can be dealt with
or avoided.
