Product Details

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. The raceways are cut into deep grooves  that have a radius closer to that of the balls than in the conventional design, using special equipment and an extremely precise cutting technique. This design allows high rigidity, high vibration/impact resistance and high damping capacity, all of which are required for machine tools, thus making  these models capable of bearing ultra-heavy loads.  


Models HNR-R

With this type, the LM block has a smaller width  (W) and tapped holes. Used in places where  the space for table width is limited.


Models HNR-LR

The LM block has the same cross-sectional  shape as models HNR-R, but has a longer overall LM block length (L) and a greater  rated load.


Models HNR-C

The flange of the LM block has tapped holes.  Can be mounted from the top or the bottom.  Can also be used in places where the table  cannot have through holes for mounting bolts.


Models HNR-LC

The LM block has the same cross-sectional  shape as models HNR-C, but has a  longer overall LM block length (L) and a greater  rated load.
