Balls roll in four rows of raceways precision-ground on an LM rail and an LM block, and ball cages and endplates incorporated in the LM block allow the balls to circulate. Use of the ball cage eliminates friction between balls and increases grease retention, thus to achieve low noise, high speed and long-term maintenance-free operation.
[Compact, Radial Type]
Since it is a compactly designed model that has a low sectional height and a ball contact structure in
the radial direction, this model is optimal for horizontal guide units.
[Superb Planar Running Accuracy]
Use of a ball contact structure that is highly resistant to loads in the radial direction minimises radial
displacement under radial loads and provides stable, highly accurate motion.
[Self-adjustment Capability]
The self-adjustment capability through front-to-front configuration of THK’s unique circular-arc
grooves (DF set) enables a mounting error to be absorbed even under a preload, thus to achieve
highly accurate, smooth straight motion.
[Stainless Steel Type also Available as Standard]
A stainless steel type with its LM block, LM rail and balls all made of stainless steel, which is superbly
corrosion resistant, is also available as standard.
With this type, the LM block has a smaller width (W) and tapped holes.
Prices are available on request.
This type has the same cross-sectional shape as SSR-XW but has a shorter overall LM block length (L).
Prices are available on request.
Since the LM block can be mounted from the bottom, this type is optimal for applications where through holes for mounting bolts cannot be drilled on the table.
