Model SR-W:With this type, the LM block has a smaller width (W) and tapped holes.
Model SR-TB:The LM block has the same height as model SR-W and can be mounted from the bottom.
Model SR-V:A space-saving type whose LM block has the same cross-sectional shape as model SR-W, but has a smaller overall LM block length (L).
Structure and Features
Balls roll in four 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 a retainer plate holds the balls, they will not fall off even if the LM block is removed from the LM rail. With the low sectional height and the high rigidity design of the LM block, this model achieves highly accurate and stable straight motion.
[Compact, Heavy Load] Since it is a compact designed model that has a low sectional height and a ball contact structure rigid in the radial direction, this model is optimal for horizontal guide units.
[Mounting accuracy can easily be achieved] Since this model is a self-adjusting type capable of easily absorbing an accuracy error in parallelism and level between two rails, highly accurate and smooth motion can be achieved. [Low Noise] The endplate installed at each end of the LM block is designed to ensure the smooth and low-noise circulation of the balls at the turning areas.
[High Durability] Even under a preload or excessive biased load, differential slip of balls is minimal. As a result, high wear resistance and long-term maintenance of accuracy are achieved.
[Stainless Steel Type also Available] A special type which LM block, LM rail and balls are made of stainless steel is also available.
