Structure and specialties

The steel ball rolls along the LM track and LM slider, forming four columns of precision ground rolling surfaces; By using a ball holder and an end cover plate assembled on the LM slider, the steel ball column is made to move in a circular motion. The use of ball retainers can eliminate friction between steel balls and improve the retention of lubricating grease, thus achieving low noise, high speed, long service life, and long-term operation without maintenance.

【 Miniaturization, radial type 】

Due to the compact design with low cross-sectional height and the steel ball contact structure with strong load-bearing capacity in the radial direction, it is most suitable for horizontal installation.

Excellent walking accuracy on a flat surface

The steel ball contact structure with strong radial load capacity is adopted, so the displacement in the radial direction is relatively small when subjected to radial load, and stable walking accuracy can be obtained.

Automatic heart adjustment ability

Due to THK's unique front combination of circular grooves (DF combination), which has automatic centering capability, it can absorb installation errors even when preloaded, resulting in high-precision, smooth and stable linear motion.

Stainless steel types have also been standardized

The stainless steel products made of LM sliders, LM rails, and steel balls with excellent corrosion resistance have also achieved standardization.
