5.2.2 Mounting instructions for bearings

The bearings must be greased after assembly according to the following

instructions:

Grease the different types of bearings as following description:

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

Ensure that grease is handled and stored properly to avoid contamination.

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.
