Greasing of bearings
The bearings must be greased after assembly, according to instructions below:
• The bearings must not be completely filled with grease. However, if space is available
beside the bearing fitting, the bearing may be totally filled with grease when mounted,
as excessive grease will be pressed out from the bearing when the robot is started.
• During operation, the bearing should be filled to 70-80% of the available volume.
• Ensure that grease is handled and stored properly, to avoid contamination.
Grease the different types of bearings as detailed below:
• Grooved ball bearings must be filled with grease from both sides.
• Tapered roller bearings and axial needle bearings must be greased in the split
condition.
