Action
To avoid contamination, let a new bearing remain in its wrapping
until it is time for fitting.
Ensure that the parts included in the bearing fitting are free from
burrs, grinding waste, and other contamination. Cast components
must be free of foundry sand.
Bearing rings, inner rings, and roller elements must not be subjec-
ted to direct impact. The roller elements must not be exposed to
any stresses during the assembly work.
Action
Tension the bearing gradually until the recommended pre-tension is achieved.
Note
The roller elements must be rotated a specified number of turns before pre-
tensioning is carried out and also rotated during the pre-tensioning sequence.
Make sure the bearing is properly aligned as this will directly affect the durab-
ility of the bearing.
Note
This instruction is not valid for solid oil bearings.
