THK 2HR1123UUM V-Groove Linear Slide Bearing Carriage

The THK 2HR1123UUM V-Groove Linear Slide Bearing, part of THK’s HR Series, is a compact precision carriage engineered to run on a matching V-groove rail for smooth, accurate, low-friction linear motion in light- to medium-duty automation. Its four-row recirculating ball design provides high rigidity and repeatable positioning, with a hardened bearing steel block and hardened steel balls; UU double-end seals protect the rolling elements from dust while retaining lubrication for extended service life. The block is grease-lubrication compatible and supports multi-directional load in a compact form factor, making it suitable for semiconductor equipment, optical inspection systems, laboratory instruments, medical devices, packaging machinery, and other precision positioning systems requiring dependable guidance and long operational life. Related replacements include THK HR1123UU, HR1530UU, and HR2045UU for upgrades or retrofits.
