The LMFA-1310/2310 measuring rails is a size 20 mm profile rail bearing with an absolute measuring scale integrated into the top surface and secured using a “snap cover” strip. The profile rail bearing is available in single sections to 3960mm. For longer lengths (to 32 M) multiple rail sections are used with a full length measuring scale.
