THK SHW27 Linear Motion Caged Ball Bearing Carriage Block

The THK SHW27 Linear Motion Caged Ball Bearing Carriage Block delivers high rigidity and precise, low-noise linear motion on SHW27 wide rails in compact, high-load systems. Designed for SHW27 wide-rail guidance, this carriage block features a four-way equal-load capacity with a low-profile 27 mm height and caged ball technology for smooth operation and long service life. It is commonly used in CNC machining centers, semiconductor manufacturing equipment, industrial automation, packaging machinery, robotic equipment, and precision material handling systems that rely on SHW27 wide rails, and maintenance teams and system integrators rely on it for machine repair, OEM replacement, and retrofit projects to restore accurate motion. Key specifications include an overall height of 27 mm, SHW27CA width 80 mm or SHW27CR width 62 mm, overall length 72.8 mm, basic dynamic load rating 16.0 kN, and basic static load rating 22.7 kN. Mounting is via M6 × 6 mm threads for the CR type, with grease or oil lubrication, and preload options Normal, C1 (light), or C0 (medium); accuracy grades include Normal, H, P, SP, and UP. Materials are hardened bearing steel, with stainless versions available, and the design is compatible with THK QZ lubrication systems for reliable performance.
