Abstract

A guide rail for a linear bearing has at least one rail element with a guideway for rolling bodies. The rail element is connected to a plastic body or borders the plastic body, with the plastic body forming the base body of the guide rail. To increase the precision of the guide rail, especially when used in an environment involving a wide temperature range, the rail element is connected to a metallic support frame which is surrounded at least partially by the material of the plastic body.
