Lubrication of the spindle drive
Interval
In order to maintain the performance values of the electric cylinder during operation, the spindle drive must be lubricated at intervals of 1,000,000 cycles.
The spindle drives are supplied lubricated from the factory. The first interval can thus be performed directly without further lubrication. To carry out lubrication, the drive is moved to a lubrication position that is easily accessible in the application. The spindle is lubricated with the help of a grease gun and the lubrication stroke is run three times according to the size.
Lubricant
Beckhoff recommends that Klüberlub BE 71-501 lubricant be used. For more information on the lubricant, please contact the manufacturer.
Lubrication position and lubrication stroke length
The approachable lubrication position is reached according to the distance in the following table. Select a lubrication position that you can approach without problems in your application in order to run the lubrication stroke in the corresponding length.

Carry out lubrication
To perform lubrication, the spindle is moved to the lubrication position and lubricated with the help of a grease gun.
- ►Loosen screw with washer [1] and take out
- ►Move spindle [1] to next possible lubrication position
Further information can be found in chapter Lubrication of the spindle drive.
- ►Lubricate lubrication point [1] using a grease gun
- ►Wipe housing dry and remove excess grease
- ►Insert screw [1] with washer [2]
- ►Tighten screw [1]
- ►Observe the tightening torques:
Component | Specification | Tightening torque [Nm] |
|---|---|---|
Screw [1] | DIN 908 M10x1 | 5.0 |
- ►Run lubrication stroke three times according to size
