The caged ball version of THK's NR and NRS series slides. The raceways in both SNR (radial type) and SNS (4-way equal) LM blocks are cut into deep grooves that have a radius closer to that of the balls in the conventional design, using special equipment and an extremely advanced cutting technique. This design provides high vibration and impact resistance, and the high damping capacity required for machine tools, making types SNR and SNS capable of bearing ultra-heavy loads greater than those that can be borne by roller slides.
