Linear guides
Linear guides form the basis of a linear bearing. They usually take the form of a metal strip with fixing holes and a raceway for the rolling elements of the bearing cages. The raceway can be flat or profiled. The main task of linear guides is to transfer pressure from the machine parts to which they are bolted to the rolling elements and to provide the rolling elements with the best possible conditions for correct operation.

General Information
J/S-type linear guides are designed for heavy-duty applications. Flat needle, roller, or ball bearing cages, either single- or double-row, are used with these linear guides.
If required, J/S-type linear guides can be equipped with end pieces and wipers on the ends.
Standard J/S linear guides are made of tool steel grade 1.2842 with a hardness range of 58–62 HRC. A stainless-steel version made of 1.4034 steel with a minimum hardness of 54 HRC is also available.
