THK Co., Ltd. HSR30LR1SS(GK) Linear Guide Block

Description:

The THK HSR30LR1SS(GK) Linear Guide is a long-type recirculating ball linear guide block designed for use with THK HSR30 series linear guide rails in high-load, high-precision linear motion applications. Featuring an extended carriage length, four-row ball contact design, and four-way equal load capability, it provides increased load capacity, excellent rigidity, smooth low-friction movement, and high positioning accuracy. Commonly installed in CNC machining centers, industrial robots, semiconductor manufacturing equipment, automated assembly systems, precision inspection machines, and material handling equipment, this linear guide block is used by maintenance teams, OEM machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK HSR30LR1SS(GK) is widely used in CNC milling machines, machining centers, gantry systems, semiconductor equipment, automated production lines, packaging machinery, precision measuring equipment, medical devices, and robotics where long carriage support, high rigidity, and precise linear positioning are required. Its extended block design provides improved moment load resistance and greater stability for demanding industrial motion control applications.
