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.

Lubrication of the spindle drive 1:

Local lack of lubrication

The 1,000,000 cycles only apply if the working stroke is greater than the lubrication stroke of the electric cylinder used. See Chapter 10.3 for further information.

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 the use of the lubricant Klüberlub BE 71-501. 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.

Lubrication of the spindle drive 2:
Loosen screw with washer [1] and take out
Lubrication of the spindle drive 3:
Move spindle [1] to next possible lubrication position

Further information can be found in chapter Lubrication position and lubrication stroke length.

Lubrication of the spindle drive 4:
Grease lubrication point [1] with grease gun
Lubrication point: DIN3405 D1 M6x1 funnel-type grease nipple

It is recommended to use a lubrication adapter:
Needle piece with 60 mm length

Wipe housing dry and remove excess grease
Lubrication of the spindle drive 5:
Insert screw [1] with washer [2]
Tighten screw [1]
