THK HSR30 Recirculating Ball Linear Guide Rail System

Description:

The THK HSR30 Linear Guide Rail Assembly is a precision linear motion system consisting of one 30 mm profile guide rail measuring 74 inches (1,880 mm) in length and one recirculating ball linear guide block. Built on THK's HSR Series with Four-Way Equal Load technology, the assembly provides high rigidity, smooth linear travel, and exceptional positioning accuracy while supporting equal load capacities in radial, reverse radial, and lateral directions. Commonly installed in CNC machining centers, industrial robots, semiconductor equipment, automated production lines, and precision positioning systems, 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 HSR30 Linear Guide Rail Assembly is ideal for CNC routers, machining centers, robotic gantries, automated manufacturing equipment, semiconductor machinery, packaging systems, material handling equipment, and precision inspection machines. The 1,880 mm (74 in.) guide rail provides long-axis travel while the recirculating ball bearing block ensures smooth, low-friction movement, high load capacity, and reliable positioning accuracy in demanding industrial environments.
