The LMF-3X0 measuring rails are a size 15 mm profile rail bearing with a measuring scale integrated into the top surface and secured using a “snap cover” strip. The profile rail bearing is available in single sections to 3940mm. For longer lengths (to unlimited) multiple rail sections are used with a full length measuring scale.

The LMF-310 version is equipped with mechanical length compensation that enables stretching of the scale to eliminate linear error. The LMF-320 version is not so equipped and all error compensation must be accomplished within the control system software.
