BM Monorail Guides
General Information
Schneeberger Monorail BM_S linear guides feature ground Gothic-profile raceways, providing four-point contact with the ball bearings, which allows load transfer in all directions (X, Y, Z). High-quality machining ensures low raceway roughness and excellent straightness, resulting in smooth and repeatable carriage motion.
Monorail BM guides are available in standard widths ranging from 15 to 45 mm.
