THK Caged Ball LM Guide Radial Type

Balls roll in four rows of raceways precision-ground on the LM rail and LM block and are circulated by ball cages and end plates incorporated in the LM block. Use of the ball cage eliminates friction between balls and increases grease retention, thus achieving low noise, high speeds, and long-term maintenance-free operation.

Compact, Radial Type


Since it is a compactly designed model that has a low cross-sectional height and a ball contact structure that is suited to large loads in the radial direction, this model is optimal for horizontal guide units.

Superb Planar Running Accuracy


Use of a ball contact structure that is suited to large loads in the radial direction minimizes radial displacement under radial loads and allows stable, highly accurate motion.

Self-Adjustment Capability


The self-adjustment capability of the front-to-front configuration of THK’s unique circular-arc grooves (DF set) enables mounting error to be absorbed even under a preload, thus achieving highly accurate, smooth linear motion.

Stainless Steel Type Also Available


A special type whose LM block, LM rail, and balls are made of stainless steel is also available.
