THK Co., Ltd. HSR30R2UU1000L Precision Linear Bearing

Description:

The THK HSR30R2UU1000L Precision Linear Bearing is a complete linear motion assembly consisting of a 1000 mm HSR30 precision guide rail and two HSR30R recirculating ball bearing blocks with double end seals (UU). Designed with THK's four-way equal load technology, this precision linear bearing system provides high rigidity, smooth low-friction movement, excellent load capacity, and accurate linear positioning for demanding industrial automation applications. Commonly installed in CNC machining centers, industrial robots, semiconductor manufacturing equipment, automated assembly systems, precision inspection machines, and material handling equipment, this linear guide assembly is used by maintenance teams, OEM machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK HSR30R2UU1000L is widely used in CNC milling machines, machining centers, gantry automation systems, pick-and-place robots, semiconductor production equipment, packaging machinery, precision measuring equipment, medical devices, and heavy-duty material handling systems. Its two-block configuration and 1000 mm rail provide exceptional rigidity, high load capacity, and precise linear motion, making it ideal for long-travel applications requiring repeatable positioning accuracy and extended service life.
