THK HSR12R1UUME290LM Linear Guide Rail Assembly

The THK HSR12R1UUME290LM Linear Guide Rail Assembly is a precision recirculating-ball linear motion system formed by one HSR12 guide rail and one HSR12R bearing block mounted on a 290 mm rail, delivering smooth, accurate motion with four-way equal-load capability for compact precision machinery and automation systems. It uses a 12 mm-wide HSR12 guide rail paired with a standard narrow HSR12R bearing block (one block total) and features top-mount with tapped bearing-block mounting, UU double-end seals, and hardened bearing steel, with lubrication compatible for grease or oil to support long service life. This configuration is commonly installed in semiconductor equipment, laboratory instruments, medical devices, small CNC machines, and automation equipment, and it is used by maintenance teams, OEM machine builders, and system integrators for repair, retrofit, expansion, and replacement. The 290 mm rail length provides a compact travel option while preserving the performance characteristics of the THK HSR12 series.
