6.2 Lubrication

WARNING
Beware of all rotating parts!
WARNING
Grease can cause skin irritation and inflammation of
the eyes.
6.2.1 Motors with permanently greased
bearings
Bearings for motor sizes 100 to 200 are usually perma-
nently greased bearings of 2Z, 2RS or an equivalent type.
Permanently greased bearings in the defined operating
conditions are guaranteed for 20,000 hours of continuous
use.

6.2.2 Motors with regreasable bearings

A. Manual lubrication
Regreasing while the motor is running
– Be sure that the lubrication channel is open
– Inject the specified amount of grease into the bearing.
– Let the motor run for one to two hours to ensure that all
excess grease is forced out of the bearing
Regreasing while the motor is at a standstill
If it is not possible to regrease the bearings while the
motors are running, lubrication can be carried out while
the machine is at a standstill.
– In this case use only half the quantity of grease and then
run the motor for a few minutes at full speed.
– When the motor has stopped, apply the rest of the
specified amount of grease to the bearing.
