While using the open-end wrench to hold the bearing pivot in the correct position, the mounting screw may be modera- tely tightened. The correct tightening torque will be checked later. 7. Move the cam roller carriage in the rail and make sure that the play / the moderate pre-tensioning is constant along the full length of the rail. The running motion should be free-mo- ving, with the cam roller carriage having any play or jamming at no point inside the rail. 8. Now tighten the mounting screw with the recommended tightening torque shown in the table, with the open-end wrench holding the angular position of the cam rollers in place. 9. Now mount the wipers, and for cam rollers carriage type N, the longitudinal seal. To do so, remove the cam roller carriage from the rail. 10.Before reinserting the cam roller carriage, make sure that the raceways / rollers are properly lubricated using a heavy duty lubricant for linear guidance. Linear guide rail systems consist of a cam roller linear guide rail GN 2422 and a cam roller carriage GN 2424. All compo- nents are packed separately and supplied not assembled. 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 the cam rollers are clean. 2. Slightly loosen the mounting screw of the central, eccentri- cally adjustable roller and insert the cam roller carriage (without the wipers supplied) into the rail (see also items 4 and 6). 3. Position the cam roller carriage at one end of the rail. For the floating bearing rails of Type UT and UV, a thin and stable support (e.g. open-end wrench or a feeler gauge) must be placed underneath the ends of the cam roller carriage body and the rail to ensure the parallel alignment of the cam roller carriage in the level raceways. Use support for floating bearing rails! 4. Insert the open-end wrench GN 2424.1 (included) bet- ween the eccentric cam roller and the cam roller carriage body. (The centering bores to the left and right mark the posi- tion of the running side of the concentric cam rollers / load- bearing cam rollers.) 5. Turning the open-end wrench clockwise will press the cam roller to be adjusted against the top raceway which will set the roller carriage free of play. Excessive pre-tensioning must be avoided because this will increase friction and redu- ce useful service life.
