TGV 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 induction hardened. They are then zinc plated to create corrosion resistant surface that is silver 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.
