TMGV Series Cam Roller Guides (replacement for the MR Series) are the most robust linear guides. The convex raceways shed dirt and debris that would otherwise inhibit the linear movement of the slider assembly. The cold drawn rails are made of carbon steel that is hardened via nitriding process. They are then post processed in a special way (i.e., proprietary NOX process) to create a very hard and durable, corrosion resistant linear rail that is black in color.
Below is a list of the slider assemblies.
Below is a listing of the linear rail available for each slider assembly. It is important to note that the slider assemblies only fit with the same series size rail.
