Cam roller linear guide rail systems GN 1490 are usually side-mounted and installed in pairs, either in a vertical (as shown) or a horizontal position. They are used for simple, linear movements, such as in automation or in vehicle and machine engineering.
Optimal travel properties combined with low maintenance requirements can be achieved with cam roller carriages matched to the guide rails without any play. The system is ready for use immediately after insertion of the cam roller carriage.
The cam roller linear guide rail systems consist of a guide rail, one or two cam roller carriages and the selected number of end stops. The parts are delivered unassembled. The guide rail can be installed on either the left or right side of the application. When installing the cam roller carriages, the direction in which the load is received (marking notch) must be taken into account. The lubrication and maintenance instructions must be followed.

During assembly, all slotted holes provided in the guide rail and the mounting threads in the cam roller carriage must be used. This ensures that the forces resulting from the maximum load FL / FA are reliably transferred to the surrounding construction. Failure to use mounting screws reduces the load capacity accordingly. Other production-related holes in the guide rails are not shown. Various screws with M5 thread can be used for mounting the cam roller carriages. In contrast, the guide rail must be mounted with the screws listed in the table. It is generally recommended to use screws of property class 8.8 in accordance with the specified tightening torque. The maximum torque for the included countersunk screws of the end stops is 4-5 Nm, which results in the highest retaining force without deforming the guide rails. The pre-assembled rubber stops are automatically clamped by the countersunk screws and thus dampen the stop of the cam roller carriages in the respective end position. |

The running surfaces of the guide rails must be lubricated with roller bearing grease before the first use. Possible lubricating greases include Cassida Grease GTX 2, Shell Gadus S2 V220 or Alvania EP 1, and Kluberplex BE 31-222. In the food or pharmaceutical sector, FDA compliant lubricating greases of class H1 or higher must be used. The grease should be distributed evenly over the entire length of the rail using a paintbrush. After 50,000 cycles, the rails should be cleaned with a clean cloth and relubricated. If there is a risk of contamination, the maintenance intervals should be shortened. However, contamination should generally be avoided with, for example, suitable covers or optimal positioning of the cam roller linear guide rail systems. |
