drylin® Q - clearance adjustment

drylin® Q square linear guides always require a minimum clearance between carriage and rail. They are supplied with pre-adjusted clearance ready for installation. The bearing clearance of the carriages can also be adjusted later if necessary. This should be done without additional load.

instructions

1. After removing the protective cover, loosen the locknuts. Width across flats: SW5 for QWE-01-20 and QWE-01-20-HKA
 
2. Reset the bearing clearance with an Allen wrench. Width across flats: 1,5mm for QWE-01-20 and QWE-01-20-HKA

instructions

3. After the adjustment, check the clearance of the carriages. If it is adequate, tighten the locknuts and attach protective cover.
 
4. In case the clearance has been set too close so that the carriage seizes, it is not enough to reset only the Allen screws. After screwing them back, additionally operate the reset button on the opposite side of the screws to release the gliding elements again. Through the steps 1-3 the clearance can be set again. Use a pin of the following size for this purpose: 2,5mm for QWE-01-20 and QWE-01-20-HKA
