THK HSR20LA1UU100L-II LINEAR MOTION BEARING GUIDE BLOCK

Description:

The THK HSR20LA1UU100L-II Linear Guide Block is a long-type precision recirculating ball linear motion bearing designed for use with THK HSR20 series guide rails. Featuring THK's Four-Way Equal Load design, the long (LA) carriage provides higher load capacity, greater moment resistance, and smoother linear motion than the standard block. Commonly installed in CNC machine tools, industrial robots, semiconductor equipment, packaging machinery, and factory automation systems, this bearing block is used by maintenance teams, OEM machine builders, and system integrators for equipment repair, retrofit, expansion, and replacement. The "-II" suffix indicates a two-set configuration for applications using two parallel guide rails.

Applications:

The THK HSR20LA1UU100L-II Linear Guide Block is ideal for CNC machining centers, precision gantry systems, robotic automation, semiconductor manufacturing equipment, medical devices, automated inspection systems, packaging machinery, and other heavy-duty linear motion applications requiring increased rigidity, long service life, and excellent positioning accuracy. The long-block design provides improved resistance to pitching, rolling, and yawing moments compared to standard-length carriages.
