Notes for mounting for bellows
The bellows is pre-assembled. The fastening screws are included. The lube nipple of the roller runner block can be used.
For type 1 and type 2, a thread M4‑10 deep, 2 x 45° must be countersunk and placed in the end face of the rail in each case.
For assembly, see "Mounting instructions for bellows".
