THK SKR Caged Ball LM Guide Actuator
THK SKR is a compact LM Guide Actuator that combines an LM Guide, ball screw and support bearing in one unit. The LM blocks and ball screw nut are built into a U-shaped outer rail. This integrated design provides high rigidity while saving space.
The SKR uses caged balls to reduce ball-to-ball friction. This supports high-speed operation, low noise and long-term maintenance-free use. The LM Guide section also provides four-way equal load capacity for flexible mounting orientations.
THK SKR is available in sizes 20, 26, 33, 46, 55 and 65. Choose from single or double long blocks, or short-block configurations where available. Motor coupling and motor-wrap configurations are offered, with high-speed operation up to 6,000 min⁻¹ for the applicable system.
