General maintenance and care instructions
All maintenance and service works must be carried out in power off and secured stage.
Caution! The motor housing can reach high temperatures during operation.
Drive systems
The toothed belt does not generally require maintenance work and will be set to the correct tension during
manufacture. Retightening is not necessary during service life with intended use. For servicing the ball screw
drive, please observe the information in the maintenance intervals and lubricant quantities section.
Please note:
I n a system that utilises two axes connected with a shaft the toothed belts in both axes should be
replaced.
Guiding systems
Because the rollers in the roller guides are equipped with lifelong lubrication, they do not need to be serviced.
Guiding system is performed during manufacture. Readjustment is unnecessary during service life with
intended use. Roller guide shafts are supplied with oil via lubricating felt located in the carriage. Please
observe the information in the maintenance intervals and lubricant quantities section.
For ball rail system maintenance, please observe the information in the maintenance intervals and lubricant
quantities section.
To ensure long term performance of the linear axis, it is necessary to perform periodic inspects for external
damage and contamination. In harsh ambient conditions with intensified contamination, the inspection
period should be adjusted accordingly to perform necessary cleaning and relubrication. Following longer
periods of linear axis use, it may be necessary to replace brush scrapers and/or sealing strip in the course
of cleaning. Please observe the following mounting instructions.
