THK HSR35LR1QZSSC0 Recirculating Ball Linear Bearing Block

Description:

The THK HSR35LR1QZSSC0 Block is a precision long-type recirculating ball linear bearing block designed for use with THK HSR35 series linear guide rails in heavy-duty, high-accuracy linear motion systems. Featuring the extended LR carriage design, integrated QZ lubricator for long-term maintenance-free operation, SS contamination seals, and C0 medium preload, this linear bearing block provides exceptional rigidity, high load capacity, smooth low-friction travel, and precise positioning accuracy for demanding industrial applications. Commonly installed in CNC machining centers, industrial robots, semiconductor manufacturing equipment, automated production lines, precision inspection machines, and material handling systems, this bearing block is used by maintenance teams, OEM machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement.

Applications:

The THK HSR35LR1QZSSC0 is widely used in CNC milling machines, machining centers, robotic automation systems, semiconductor equipment, precision measuring machines, packaging machinery, medical equipment, and automated manufacturing lines. Its long narrow block design combined with the QZ lubrication system and C0 preload provides superior rigidity, increased moment load capacity, stable high-speed operation, and extended maintenance intervals in applications requiring precise linear motion and long service life.
