MONORACE ML Series linear guides are designed to be a low cost linear guide system with versatile load handling capabilities for general purpose applications. The rail is made of carbon steel that has been hardened through high depth nitriding. It is then treated with the innovative TRACE-NOX process which delivers excellent corrosion resistance. The rail features a “C” shaped cross section with a polished interior and a concave raceway for smooth low noise motion. Included in the ML Series are the RL Sliders and L. Rollers. RL sliders are engineered to be practical and functional in many different industries. Equipped with 2Z sealed high precision rollers that remain lubricated for the life of the product and a body of zinc coated steel. L. Rollers are high quality single row ball bearings that have an integrated roller pivot for exceptional control of preload setting in different systems. The bearings are made of core hardened carbon steel and an inner ball retainer that is able to withstand extremely high temperatures.
