General Assembly Instructions
The worm gear screw jack is fastened via the housing or other fastening components (mounting plates or
cardan adapters, see QR code below). The housing always needs to be screwed to a machined surface (not
to rolled steel profiles or similar) in order to avoid misalignment or noise.
Depending on the respective application, the worm gear screw jack and the screw have to be precisely
aligned at a right angle or in parallel to the machine component and tightened during assembly.
The tolerances of the four assembly sides correspond to the DIN ISO 2768-mH standard.

The torques mentioned in the table are only rough and nonbinding guidelines – see VDI 2230.
Lateral forces have to be absorbed by suitable guiderails; otherwise the device lifecycle would be shortened.
Attention!
The lubrication nipples must always be accessible during operation.
Attention!
Do not hammer the shaft end or the screw when aligning the worm gear screw jack.
