Thk SHW17CR2UUM310L Caged Ball Linear Motion Guide Wide-Rail

Description:

The THK SHW17CR2UUM310L Caged Ball Linear Motion Guide Wide-Rail is a complete linear motion assembly consisting of two SHW17CR bearing blocks mounted on a 310 mm SHW17 wide linear guide rail, designed to provide compact, high-rigidity, and precision linear motion. Commonly installed in semiconductor manufacturing equipment, medical devices, factory automation systems, precision inspection machines, compact robotics, and electronic assembly equipment where high moment rigidity and smooth operation are required. Maintenance teams and system integrators use this assembly for machine repair, OEM replacement, retrofit projects, and new precision automation systems.

Applications:

The THK SHW17CR2UUM310L is designed for compact linear motion applications that require excellent rigidity, low-profile construction, and accurate positioning. Its wide-rail configuration provides superior resistance to moment loads while maintaining smooth, low-friction travel, making it ideal for laboratory automation, vision systems, pick-and-place equipment, packaging machinery, semiconductor equipment, and precision manufacturing systems.
