Stainless steel linear guide rail systems are made up of stainless steel cam roller linear guide rails GN 2492 and stainless steel cam roller carriages GN 2494. All required components are provided unassembled in separate packages.
When delivered, the play between cam roller carriage and rail is not preset. During assembly, set the cam roller carriage as follows:
1. Make sure that the raceways and guide rollers are clean.
2. Loosen the fixing screw of the central adjustable eccentric guide roller slightly and insert the cam roller carriage into the guide rail without the wipers (see steps 4 and 6).
3. Position the roller carriage at one end of the guide rail.
4. Insert the open-end wrench between the eccentric roller and the cam roller carriage. The two centering holes on the left and right of the cam roller carriage mark the position of the running side for the two concentric and supporting rollers.
5. Turning the wrench clockwise presses the guide roller against the support raceway of the rail so that there is no play for the roller carriage. Overtightening will increase friction and reduce the service life of the item.
6. While holding the bearing pivot of the eccentric guide roller in place with the wrench, tighten the fixing screw moderately. The precise torque will be checked later.
7. Move the cam roller carriage in the guide rail and make sure that the play or slight preload is consistent across the entire length of the rail. The cam roller carriage should move easily without being overly loose or tight. Adjust if necessary.
8. Tighten the fixing screw using the torque specified in the table (observe construction height h1). Use the open-end wrench to hold the eccentric guide roller at its final angle to prevent accidental adjustments. Adhesive can also be used to fix the screw in position.
h1 (construction height) | Torque |
30 | 6 Nm |
45 | 10 Nm |
9. Insert the wipers. Take the roller carriage out of the rail and reinsert it to check where the wipers will go. The wipers will self-align during use.
