THK NR-X, NR, NRS-X & NRS Super-Heavy Load LM Guide

THK NR-X, NR, NRS-X and NRS are super-heavy load LM Guides designed for machine tools. Their deep-groove raceways increase the contact area between the balls and raceways. This provides high rigidity, strong vibration and impact resistance, and high damping capacity.

The NR-X and NR are radial types for radial loads. The NRS-X and NRS are 4-way types for loads in four directions. Both types are available in the same sizes and let you choose the design that best matches the required load direction.

The series is available in sizes from 25 to 100. Different LM block designs are available, including narrow, long and ultra-long blocks, as well as flange types for different mounting needs.
