THK HSR35CA1SS(GK) LINEAR BLOCK BEARING

Description:

The THK HSR35CA1SS(GK) Block Bearing is a precision recirculating ball linear guide block designed for use with THK HSR35 series linear guide rails in high-load, high-accuracy linear motion systems. Featuring a flange-type carriage, SS sealing configuration, and GK interchangeable specification, this linear bearing block delivers smooth low-friction travel, high rigidity, and four-way equal load capacity for reliable performance under loads from any direction. Commonly installed in CNC machining centers, industrial robots, semiconductor manufacturing equipment, automated assembly lines, precision inspection systems, and material handling equipment, this bearing block is used by maintenance teams, OEM machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK HSR35CA1SS(GK) is widely used in CNC milling machines, machining centers, robotic automation systems, semiconductor production equipment, packaging machinery, precision measuring equipment, medical devices, and factory automation systems. Its four-row recirculating ball design and flange-type construction provide excellent rigidity, high load capacity, and precise linear positioning, making it ideal for demanding industrial applications requiring smooth motion and long service life.
