Thk SHW27 Linear Motion Caged Ball Bearing Carriage Block

Description:

The THK SHW27 Linear Motion Caged Ball Bearing Carriage Block is a wide-profile linear guide block designed for SHW27 series guide rails, providing high rigidity, excellent moment load capacity, and precise linear motion in demanding industrial applications. Commonly installed in CNC machining centers, semiconductor manufacturing equipment, industrial automation systems, packaging machinery, robotic equipment, and precision material handling systems using SHW27 wide rails. Maintenance teams and system integrators use this bearing block for machine repair, OEM replacement, retrofit projects, and restoring smooth, accurate linear motion.

Applications:

The THK SHW27 bearing is engineered for compact linear motion systems requiring superior rigidity and high moment resistance from a single wide rail. Its low-profile, caged ball design delivers smooth, low-noise operation and long maintenance intervals, making it ideal for automated assembly equipment, vision systems, medical devices, precision inspection machines, electronic manufacturing equipment, and industrial robotics.
