Selection of shaft

For the units with cylindrical bore (with set-screws or eccentric locking collar) clearance fit is usually favoured for mounting the units on the shaft.

Regreasing intervals

The usable life of the grease is influenced by many factors.The regreasing intervals in our table thus can only be seen as very rough estimates.  Experience with comparable bearings or ones already used is therefore very important as not all operating conditions and influential factors that affect the service life of a lubricant – and hence also the bearing – are known or determinable in many cases.
