THK SR Radial Full-Ball LM Guide
THK SR is a radial full-ball LM Guide for smooth and accurate linear motion. Its compact, low-profile design provides high rigidity and supports large radial loads. This makes it suitable for horizontal guide units.
The SR uses four rows of balls with a 90° contact angle. This structure provides high radial rigidity and stable motion. Its self-adjusting design can also absorb parallelism and level errors between two rails.
THK SR is available in sizes 15 to 150. The series includes W, V, T, TB and SB block types for different mounting and space requirements. Stainless steel versions are also available, while tapped-hole LM rails can be specified for selected models.
