Abstract

A guide rail for a linear bearing has a longitudinal axis, a first and second diametrically opposed lateral surface and a top lateral surface, running surfaces provided on the first and/or second lateral surfaces and extending parallel to the longitudinal axis, for a guide carriage of the linear bearing, and an incremental dimensional standard for a position measuring device provided on one of the lateral surfaces, wherein an absolute dimensional standard is provided on another lateral surface, which is scanable by the position measuring device together with the incremental dimensional standard in order to determine an absolute position.
