Roller guide system T-Rase series ML

System of the linear guideways of ML series consists of the steel rail of C-shaped profile itself with a concave profile of circulation path. The precise rollers are equipped with a lubricant for all service life and have the protection 2Z. The sliders can be supplied with three or five rollers, including the sprags, to adjust the preload of the slider. Both ends of the slider have the polyamide scrapers to remove the debris and grease from the impregnated felt scrapers, lubricating the circulation paths for a long service life and minimization of service.


Roller guideways system of ML series


The sliders consist of coaxial rollers and sprags. The sprags are used to set the preload in the system to prevent different kinds of backlash. Value of preload is adjusted depending on the problems that are performed in a specific application. The sliders are able to perceive the loads and moments of forces in all directions. Since one circulation path is contacted with a large number of rollers than another, so this is the main path for receive of the radial loads. The main direction of the radial load is indicated on the slider by two round marks. The internal circulation paths of C-shaped rail are protected from the different types of accidental damage. Moreover the rollers are also protected inside the rail at the one side and by the slider housing on the other side. In general, guideway systems of ML series are easy to construct and install, and they are compact in size.

Description of the series

Roller guideways of ML series

Sliders of RL series are made of galvanized steel housing with the mounting holes that are parallel to the axes of rollers and perpendicular to the main base load. Sliders have the seals with the oil-impregnated felt, for the lubrication of circulation paths. The sliders of RL series have 2 sizes, and each one has 3 or 5 rollers.

Roller guideways of ML series

Sliders of RLS series have a very thin housing as the most of compact sliders, but without compromising for productivity. These sliders have two series of the mounting holes. Holes can be performed as the threaded or through mounting (RLS and RLS**C). Standard slider housing is made of galvanized steel, but also can be made of stainless steel. The sliders have 2 sizes and consist of 3, 4 or 5 rollers.

Technical description

The rails of ML series are manufactured in 2 sizes - 28mm and 43mm - with two types of the mounting holes: ML**L series is for the screws with TORX low cylindrical head that are supplied with the rails; ML**S series is for the screws with a conical head for concealed mounting by ISO5933 standard. The rail has a C-shaped cross-section with the deep inner circulation paths. The circulation paths are polished for smooth and silent motion of the rollers. The inner circulation paths are protected by external rail walls from the different accidental damages. C-shape also protects the rollers. The rails of ML 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.
