THK Co., Ltd. HSR30R2UU1000L Precision Linear Bearing

The THK HSR30R2UU1000L is a complete precision linear bearing assembly built around a 1000 mm THK HSR30 guide rail and two HSR30R recirculating-ball blocks with UU double-end seals, delivering high rigidity and smooth, low-friction motion. With THK's four-way equal-load design, it supports demanding long-travel applications and provides a dynamic load rating of 40.5 kN and a static load rating of 53.7 kN, while promoting repeatable positioning and long service life. The rail is 30 mm in cross-section, 28 mm wide and 26 mm high, made from hardened alloy steel, and uses a bolt-mounted mounting method with grease or oil lubrication. This two-block assembly is commonly used in CNC milling machines, machining centers, gantry automation systems, semiconductor equipment, automated assembly lines, precision measuring devices, and heavy-duty material handling, and it is selected by maintenance teams, OEM machine builders, and system integrators for repair, retrofit, expansion, or replacement.
