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
RW1808 linear guides feature two parallel V-shaped profiles, allowing for the integration of a high-load-capacity linear in a compact size. With HRW08 bearing cages containing two rows of rollers set at a 45° angle, RW1808 guideways can carry loads in all directions.
If required, RW1808 guides can be equipped with end pieces.
Standard RW1808 linear guides are manufactured from tool steel grade 1.2842 with a hardness of 58-62 HRC. A stainless-steel version made of 1.4034 steel with a minimum hardness of 54 HRC is also available.
