THK Co., Ltd. HRW27-UP5D14-1-520L Linear Motion Guide

The THK HRW27-UP5D14-1-520L Linear Motion Guide is a precision, wide-profile recirculating-ball guide assembly that mounts a HRW27 wide-flanged bearing block on a 520 mm precision-ground rail, delivering smooth, rigid and highly accurate linear motion for demanding automation. This 520 mm rail length uses a 27 mm rail size with a 48 mm rail width and 13 mm rail height, while the bearing block measures 27 × 80 × 72.8 mm (H × W × L) in HRW27CA form and features through-hole precision-ground mounting with a 60 mm hole pitch and a 20 mm end distance G. The system supports four-way equal load direction (radial, reverse radial, and lateral) and provides high rigidity with dynamic load rating of 14.2 kN and static load rating of 21.6 kN. Lubrication is grease- or oil-compatible, and the assembly uses hardened bearing steel with precision-ground raceways for long-lasting accuracy. Commonly used in CNC machining centers, robotic positioning systems, automated assembly equipment, semiconductor processing machinery, packaging lines, medical devices, and vision inspection systems, the HRW27-UP5D14-1-520L is suitable for equipment repairs, retrofits, and high-precision linear motion upgrades by OEMs, maintenance teams, and system integrators.
