Note
Regreasing of the labyrinth seal
The labyrinth seal is filled with grease. It must be regularly regreased depending on the ambient conditions.

Procedure
1.

Use the greases from table T 7300 for the regreasing. The grease quality must meet the requirements specified in the

table.

2.

The reference value for regreasing is 30 g lubricating grease after 3000 operating hours.

3.

Using a grease gun, inject the grease into the bearing point via the nipple provided.

You have regressed the labyrinth seal.
