Thk HSR30 Linear Bearing Guide Rail 3-Block 30mm x 2160mm 85 L

Description:

The THK HSR30 Linear Bearing Guide Rail Assembly is a complete linear motion system consisting of one 30 mm precision guide rail measuring 2,160 mm (85 in.) in length and three THK HSR30 recirculating ball linear guide blocks. Designed with THK's Four-Way Equal Load technology, the assembly delivers smooth, high-rigidity linear motion, high load capacity, and exceptional positioning accuracy for long-travel industrial applications. Commonly installed in CNC machining centers, industrial robots, semiconductor equipment, gantry systems, and automated production machinery, this assembly is used by maintenance teams, OEM machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement. THK's HSR series provides equal load ratings in radial, reverse radial, and lateral directions for reliable operation in any mounting orientation.

Applications:

The THK HSR30 Linear Bearing 3-Block Guide Rail Assembly is widely used in large CNC routers, machining centers, robotic gantries, automated production lines, semiconductor manufacturing equipment, material handling systems, inspection machines, packaging equipment, and precision positioning applications. The long 2,160 mm guide rail combined with three bearing blocks provides increased load distribution, enhanced rigidity, and stable motion for long-axis travel and heavy-duty industrial automation.
