INSTALLING BEARINGS
Approximately 16% of all early pill accidents are caused by faulty mounting (generally excessive force) and lack of proper tools.
DROPPING BEARINGS
The need for dismantling (removal) of the bearing can be caused by several reasons: failure of the bearings, disassembly of other parts of the mechanism, and so on.
SELECTION OF FUEL OILS
The use of grease to lubricate the bearings ensures smooth operation and maximum reliability of bearings, even in extreme conditions.
