THK HSR30A Linear Rail With Linear Ball Bearing Block

Description:

The THK HSR30A Linear Rail with Linear Ball Bearing Block is a precision linear motion assembly consisting of a THK HSR30A recirculating ball bearing block mounted on an HSR30 profile guide rail. Designed with THK's Four-Way Equal Load technology, it provides high rigidity, smooth linear travel, and equal load capacity in radial, reverse radial, and lateral directions for demanding motion control applications. Commonly installed in CNC machining centers, industrial robots, semiconductor equipment, automated production systems, and precision machinery, this assembly is used by maintenance teams and system integrators for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK HSR30A Linear Rail with Linear Ball Bearing Block is widely used in CNC machine tools, robotic automation, semiconductor manufacturing equipment, packaging machinery, material handling systems, precision inspection machines, and factory automation systems. Its four-way equal load design delivers stable, low-friction linear motion with excellent positioning accuracy and rigidity, making it suitable for high-speed and high-load industrial applications.
