THK 2HR1123UUM V-Groove Linear Slide Bearing Carriage

Description:

The THK 2HR1123UUM V-Groove Linear Slide Bearing is a compact precision linear guide carriage designed to travel on a matching V-groove rail, providing smooth, accurate, and low-friction linear motion for light- to medium-duty automation applications. Commonly installed in semiconductor equipment, optical inspection systems, laboratory instruments, medical devices, packaging machinery, and precision positioning equipment requiring reliable linear guidance. Machine builders, maintenance technicians, and automation integrators use this bearing for new machine construction, equipment upgrades, precision retrofits, and replacement of worn linear slide components.

Applications:

The THK 2HR1123UUM belongs to THK's HR Series linear guide family, engineered with a precision recirculating ball bearing design that delivers smooth motion, high rigidity, and excellent positioning accuracy. The UU suffix indicates double end seals that protect the rolling elements from dust and contaminants while retaining lubrication for extended service life. Its compact profile and V-groove guidance make it suitable for high-speed, repeatable motion in cleanroom environments, electronic assembly equipment, precision measuring systems, and automated production machinery where dependable linear movement and long operating life are required.
