THK HSR20LR1DDM (GK) LINEAR GUIDE RAIL BLOCK HSR-20 HSR20

Description:

The THK HSR20LR1DDM (GK) Linear Guide Rail Block is a long-type precision recirculating ball linear bearing designed for use with THK HSR20 series guide rails. Its extended block length provides higher load capacity, improved rigidity, and smoother linear motion than the standard HSR20 block. Commonly installed in CNC machining centers, industrial robots, semiconductor equipment, packaging machinery, and automated production systems, this linear guide block is used by maintenance teams, OEM machine builders, and system integrators for machine repairs, retrofits, and replacement of worn linear motion components.

Applications:

The THK HSR20LR1DDM (GK) Linear Guide Rail Block is ideal for CNC machine tools, robotic positioning systems, semiconductor manufacturing equipment, automated assembly lines, medical equipment, packaging machines, precision inspection systems, and factory automation applications requiring high rigidity, long service life, four-way equal load capacity, and precise linear positioning. Its long-block design offers greater moment load resistance for demanding industrial applications.
