THK HRW21CA2UUC1380LP Bearing Block With Linear Rail

The THK HRW21CA2UUC1380LP Bearing Block with Linear Rail is a complete precision linear motion assembly featuring two HRW21CAUU carriage blocks factory-mounted on a 1380 mm HRW21 guide rail. Designed for high rigidity and accurate positioning, the dual-carriage configuration distributes load across two blocks for stability in demanding automation tasks, with a 1380 mm rail length, 37 mm rail width, and 11 mm rail height, a CA flanged carriage block, and four-way equal load capability. This THK wide-rail LM guide uses hardened bearing steel, supports top or bottom mounting, operates from -20°C to 80°C, and accepts grease or oil lubrication with UU double-end seals, making it suitable for CNC machining centers, robotic positioning systems, semiconductor manufacturing equipment, automated assembly lines, pick-and-place systems, packaging machinery, medical equipment, and precision inspection systems where long-travel, high-load, and high-accuracy linear guidance is required. The assembly offers a low-profile design, self-aligning capability, smooth low-friction operation, and high positioning accuracy, with a basic dynamic load rating of 8.02 kN and a basic static load rating of 12.9 kN per single block.
