The specified relubrication intervals are valid for maximum ambient temperatures of 40 °C.
Reduce the relubrication intervals for a
10°C increase in temperature by a factor of 0.7 of the value listed in the table (max. 20
°C = factor 0.5). Times for operation on 60 Hz systems on request.
9.1.7.3 Regreasing intervals and types of grease for operating rolling-contact bearings
Regreasing intervals
The
regreasing intervals for roller bearings in operating hours and the grease types are stated
on the machine's lubricant plate. Regardless of the actual number of operating hours reached,
the machine must be regreased at least once a year. The lubrication information can be found
on the lubricant plate.
Note
Observe the regreasing intervals for the roller bearings
The regreasing intervals for roller bearings are different from the service/inspection intervals
for the machine. Failure to regrease the roller bearings at the specified intervals can result in
bearing damage.
