Low noise, high speed, long lifespan, and long-term maintenance-free are achieved.
The balls roll on the four-row rolling surfaces precisely ground on the LM rail and LM block, and the ball retainer and end plate integrated into the LM block circulate the ball rows. By adopting this ball retainer, mutual friction between the balls is eliminated, and the grease retention capability is improved, resulting in low noise, excellent high-speed performance, and achieving long life with long-term maintenance-free operation.

basic information
● Compact Radial Type This is a compact type with a low cross-sectional height, optimized for horizontal guideways due to its 90° ball contact structure in the radial direction. ● Excellent Flat Running Accuracy By adopting a 90° ball contact structure in the radial direction, the displacement in the radial direction under radial load is minimized, resulting in stable running accuracy. ● Automatic Adjustment Capability Thanks to THK's unique circular arc groove front combination (DF set), the automatic adjustment capability allows for the absorption of mounting errors even when preloaded, achieving high-precision and smooth linear motion. ● Stainless Steel Standardization Stainless steel, which has excellent corrosion resistance, is now standardized for LM blocks, LM rails, and balls.
