The ball bearings roll along the SR guide rail and the four rows of rolling surfaces, which are precision ground on the slider; the ball bearing rows are cycled through by assembling end cover plates onto the LM slider.

Due to the low-section-height, miniaturized design types featuring a steel ball contact structure with strong radial load-bearing capacity, they are suitable for horizontal guidance sections.

With THK's expertise in materials, heat treatment, and lubrication, the high-temperature LM rolling guide SR-M1 model achieves a working temperature of up to 150°C.

Operating Temperature: 150℃

By using stainless steel for the end cover plate and high-temperature rubber for the end sealing pad, the working temperature has been achieved up to 150°C.

Dimensional Stability

Due to size stabilization processing, this type exhibits excellent dimensional stability after heating or cooling (note the thermal expansion at high temperatures).

High corrosion resistance

Due to the use of corrosion-resistant stainless steel in LM sliders, LM tracks, and steel balls, these models are suitable for use in cleanrooms.

High-Temperature Oils

This model uses high-temperature grease, which exhibits minimal change in rolling resistance even as the temperature shifts from ambient to high.
