Mounting components
Mounting brackets
Mount the brackets on either side of the coupling on either the shafts or on the solid coupling hubs,
and both at the same rotational position.
Please note the following in order to obtain the highest possible measurement accuracy and to avoid
damage to equipment:
Ensure that the brackets fit solidly onto their mounting surfaces! Do not use self-constructed
mounting brackets, or modify the original bracket configuration supplied by PRÜFTECHNIK
(for example, do not use support posts longer than those supplied with the bracket).
1. Choose the shortest support posts which will still allow the laser beam to pass over or through the
coupling. Insert the support posts into the bracket.
2. Fasten them in place by tightening the hex screws on the sides of the bracket frame.
3. Place the bracket on the shaft or coupling, wrap the chain around the shaft and feed it through the
other side of the bracket: if the shaft is smaller than the width of the bracket frame, insert the chain
from the inside of the bracket as shown in the diagram; if the shaft is larger than the bracket width,
insert the chain into the frame from the outside.
4. Catch the chain loosely on the anchor peg.
5. Turn the bracket thumbscrew to tighten the assembly onto the shaft.
6. Clip the loose end of the chain back onto itself.
The bracket should now be tight upon the shaft. Do not push or pull on the bracket to check, since
this could loosen its mounting.
To remove the brackets, loosen the thumbscrew, then remove the chain from its anchor peg.
