 Technical description

The rails of MR series are manufactured in 3 sizes - 18mm, 28mm and 43mm - with two types of the mounting holes. MR**L series is the rail with holes with cylindrical countersinking, for the special screws with low cylindrical head that are supplied with the rail. MR**S series is the rail with holes for standard countersunk head screws of ISO5933. The rail has a C-shaped cross-section with the convex inner circulation paths. The circulation paths are polished for smooth and silent motion of the rollers. The inner paths are protected from outside impacts and other types of effects that could damage the circulation surface.

The rail shape also protects the rollers from various damages. The rails of MR series are made from carbon steel and hardened by the deep nitriding. The rail surface is treated with a special innovative method TRACE-NOX, which provides the excellent protection against corrosion. The coverage is not sprayed, which can be scraped, the coating is deeply implanted into the surface material. The result is a very proof and long lasting protective effect against the rail corrosion, which has a black color due to micro impregnation of the oil and antioxidants.
