THK SHW17CR2UUM310L Caged Ball Linear Motion Guide Wide Rail

The THK SHW17CR2UUM310L Caged Ball Linear Motion Guide Wide-Rail Assembly combines two SHW17CR bearing blocks on a 310 mm SHW17 wide rail to deliver compact, high-rigidity, and precise linear motion in a single, install-ready package. Its wide-rail design provides high moment rigidity and smooth travel while maintaining a low profile, with self-adjusting alignment and low noise for reliable long-term operation. Key specifications include a rail length of 310 mm, rail width of 50 mm, and a 17 mm rail cross-section, driven by two SHW17CR blocks and bolted from above; the assembly uses hardened bearing steel and offers grease or oil lubrication, with preload options Normal, Light Preload, or Medium Preload, and accuracy grades Normal, High (H), Precision (P), Super Precision (SP), and Ultra Precision (UP). The setup delivers a Basic Dynamic Load Rating of 7.65 kN and a Basic Static Load Rating of 10.18 kN to support demanding tasks. Common uses span semiconductor equipment, medical devices, factory automation, precision inspection machines, laboratory automation, vision systems, pick-and-place and packaging machinery, compact robotics, and other precision manufacturing systems, where system integrators rely on robust, low-friction motion to achieve accurate, repeatable results.
