☞ Now secure the rack permanently with straight pins. We recommend to us hardened

straight pins acc. to DIN EN ISO 8734.

☞ All racks must be pinned in addition to being fastened with fixing screws in order to

prevent micro-sliding. This additional pinning prevents the rack from changing its

position and also the fixing screws from loosening.

☞ Notice applicable to tensioning gearboxes: If the torque is transmitted via a tensioning

gearbox or tensioning system where 2 pinions are in mesh on the same rack, the entire

torque must not exceed the displacement force of the screws. The rack should be as

long as possible but not shorter than 1 meter. Please contact us.

Mounting the gear unit

In the case of Z axes (vertical assembly) the machine table must be

properly secured before positive connection with rack and gear unit because otherwise it

could roll off due to its own weight and cause personal injury and material damage.

☞ Mount the gear unit provisionally on the machine table. Do not yet fully tighten the

fixing screws. Mounting example: see picture below.

Before mounting the gear unit on the machine

table it must be equipped with pinion shaft

and lubricator.

(See separate instructions).

The machine table must be designed in such

a way that the gear unit can be readily

mounted and adjusted.

An example is shown on the picture below.
