THK HRW17CA Linear Bearing and Guide Rail Set

Description:

The THK HRW17CA Precision Linear Bearing Way Set 39-Inch is a complete linear motion assembly consisting of an HRW17CA bearing block and approximately a 39-inch (991 mm) precision guide rail, designed to provide smooth, accurate, and high-rigidity linear motion. Commonly installed in CNC machines, semiconductor equipment, automated assembly systems, packaging machinery, medical equipment, and industrial robotics requiring compact, wide-rail linear guidance. Maintenance teams, OEM machine builders, and system integrators use this bearing way set for machine repairs, linear guide replacements, automation retrofits, and precision motion system upgrades.

Applications:

The THK HRW17CA Bearing Way Set is widely used in CNC machining centers, pick-and-place machines, semiconductor manufacturing equipment, laboratory automation, vision inspection systems, packaging machinery, industrial robots, and precision positioning equipment where a compact wide-rail guide provides excellent rigidity and smooth linear travel over approximately 39 inches (991 mm).
