4.2.1. Mounting instructions for bearings
General
This section details how to mount and grease different types of bearings on the robot.
Equipment
Assembly of all bearings
Follow the instructions below when mounting a bearing on the robot.
Assembly of tapered bearings
Follow the previous instructions for assembly of all bearings, when mounting a tapered
bearing on the robot.
In addition to those instructions, the procedure below must be carried out to enable the roller
elements to adjust to the correct position against the race flange.
Equipment, etc.
Art. no.
Note
Grease
Oil and Grease spec-
ification on page 199
Action
Note
1. To avoid contamination, let a new bearing remain in its wrapping
until it is time for fitting.
2. Ensure that all parts included in the bearing fitting are free from
burrs, grinding waste and other contamination. Cast components
must be free from foundry sand.
3. Bearing rings, inner rings and roller elements must under no cir-
cumstances be subjected to direct impact. Furthermore, the roller
elements must not be exposed to any stresses during the assembly
work.
Action
Note
1. Tension the bearing gradually until the recommended pre-tension
is achieved.
NOTE!
The roller elements must be rotated at a specified number of turns
before pre-tensioning is carried out and also rotated during the pre-
tensioning sequence.
2. Make sure the bearing is properly aligned, as this will directly affect
the lifespan of the bearing.
