The bearings must be greased after assembly according to the following
instructions:
• 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 following description:
• 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.
