THK HRW27CA1UU180L Linear Carriage Guide Assembly

The THK HRW27CA1UU180L Linear Carriage Guide combines a factory-mounted HRW27CAUU flanged bearing block with an 180 mm wide-profile HRW27 guide rail to deliver precise, smooth, high-rigidity linear motion via a recirculating-ball linear motion guide for industrial automation and precision machinery. This single-bearing-block assembly is designed for precision through-hole rail mounting over a 180 mm rail length, with a 27 mm rail size, 48 mm rail width, and 13 mm rail height, and uses UU double-end seals for clean operation. The block itself measures 27 × 80 × 72.8 mm (H × W × L) and employs hardened bearing steel with precision-ground raceways to provide a dynamic load rating of 14.2 kN and a static load rating of 21.6 kN in a four-way equal-load design. Lubrication is compatible with grease or oil, and the bearing guide delivers low-friction, high-positioning-accuracy performance with a compact, self-aligning, wide-rail profile. Typical applications include CNC machining centers, robotic positioning systems, semiconductor processing equipment, pick-and-place machines, packaging machinery, medical and vision inspection systems, and broader factory automation where 180 mm rail length, compact installation, and high rigidity are required; maintenance teams, OEM machine builders, and system integrators frequently use this assembly for repairs, retrofits, or replacement of worn linear guides. Common replacements include THK HRW27CAM1UU180L, THK HRW27CR1UU180L, and THK HRW27CRM1UU180L.
