Regreasing intervals
Note
The relubrication interval of the bearing depends on the temperature and the load
For tempera
tures above +70 °C, the regreasing interval must be reduced by half for each
temperature increase of 15
K.
For moderate shock loading and vibration, the regreasing interval must be reduced by 20%.
For heavy loading, the regreasing interval must be reduced by half.
The regreasing interval is valid for a temperature of +70 °C, measured on the surface of the
housing in the vicinity of the bearing.
Regrease the bearing after the following number of operating hours.

Roller bearing grease
NOTICE
Impermissible mixing of roller bearing greases results in damage
Residual quantities of original oil can impair the specific properties of the new oil.
When regreasing, do not mix greases with a different soap base.
For regreasing, use the recommended roller bearing grease.
Using a grease gun, inject the grease into the bearing point via the lubricating nipples
provided.
