THK HSR30A1SS Linear Guide Block Flange Type A

Description:

The THK HSR30A1SS Linear Guide Block is a precision recirculating ball bearing carriage designed for use with THK HSR30 profile linear guide rails in high-load linear motion systems. Featuring a standard flange-type configuration with THK's four-row, four-way equal load design, it provides smooth linear travel, high rigidity, and excellent positioning accuracy in all mounting orientations. Commonly installed in CNC machining centers, industrial robots, semiconductor manufacturing equipment, packaging machinery, and factory automation systems, this guide block is used by maintenance teams, machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK HSR30A1SS is widely used in CNC milling machines, machining centers, gantry systems, pick-and-place robots, semiconductor equipment, automated assembly lines, precision inspection machines, medical equipment, and material handling systems. Its high load capacity, low-friction operation, and four-way equal load capability make it suitable for precision linear motion applications requiring long service life and consistent accuracy.
