THK SHW17CR1UUM270LM Linear Motion Bearing Assembly

The THK SHW17CR1UUM270LM is a compact wide-rail linear motion bearing assembly that pairs one SHW17CR bearing block with a 270 mm SHW17 rail for precise, low-profile linear motion in space-constrained machinery. Built with stainless steel M-designation rail and block and a four-way equal-load geometry, it delivers high moment rigidity and corrosion resistance with smooth, repeatable movement and a self-adjusting capability. Key specifications include a rail width of 50 mm, rail length 270 mm, rail size 17 mm, block height 17 mm, dynamic load rating of 4.31 kN, static load rating of 5.66 kN; lubrication is grease or oil, and mounting is bolt mounted from above. The wide-rail design, long maintenance intervals, and low-noise operation support high-precision positioning in compact packages. The block is CR type (standard block with top mounting holes). Common applications span semiconductor equipment, medical devices, factory automation systems, precision inspection equipment, packaging machinery, and compact robotic applications, with particular usefulness for precision stages, electronics manufacturing equipment, laboratory automation, vision systems, and automated assembly machinery. Maintenance teams and system integrators use this assembly for machine repair, OEM replacement, retrofit projects, and new precision automation systems.
