Features
Structure and Features
With models RSR and RSR-W, balls roll in two rows of raceways precision-ground on an LM rail and an LM block, and endplates incorporated in the LM block allow the balls to circulate.Since balls circulate in a compact structure, the LM Block is able to provide infinite straight motion and thus infinite stroke.The LM block is designed to have a shape with high rigidity in a limited space, and in combination with large-diameter balls, demonstrates high rigidity in all directions.
Ultra-Compact
The absence of cage displacement, a problem that cross-roller guides and types of ball slides with finite stroke tend to cause, make these models highly reliable LM systems.
Capable of Receiving a Load in Any Direction
These models are capable of receiving loads in all directions, and a single-rail guide can adequately operate under a small moment load. Model RSR-W, in particular, has a greater number of effective balls and a broader LM rail to increase its rigidity against a moment. Thus, it achieves a more compact structure and more durable straight motion than a pair of linear bushes in parallel use.
Stainless Steel Type also Available
A special type where LM block, LM rail and balls are made of stainless steel is also available.
Accuracy of the Mounting Surface
Model RSR uses Gothic arch grooves in the ball raceways. When two rails of RSR are used in par- allel, any error in accuracy of the mounting surface may increase rolling resistance and negatively affect the smooth motion of the guide. For specific accuracy of the mounting surface, see Flatness of the Mounting Surface.
