THK SHS45LC2KKHHS675LK Linear Motion Bearing Assembly

The THK SHS45LC2KKHHS675LK Linear Motion Bearing Assembly is a complete precision linear motion solution comprised of two SHS45LC long bearing blocks factory-mounted on a 675 mm SHS45 linear guide rail, delivering high-load, high-accuracy motion. Commonly installed in CNC machining centers, factory automation equipment, robotic systems, semiconductor manufacturing equipment, packaging machinery, and precision inspection machines, it is also favored by maintenance teams and system integrators for machine repair, OEM replacement, retrofit projects, and new automation systems requiring a preassembled linear guide. Technical specifications include a 45 mm rail size on a 675 mm rail, THK as manufacturer, bearing type: caged ball, block type: long flange (LC), two bearing blocks on one rail, four-way equal load, bolt-mounted-from-above rail mounting, hardened bearing steel construction, grease or oil lubrication, preload options Normal, Light Preload (C1), and Medium Preload (C0), plus accuracy grades Normal, High (H), Precision (P), Super Precision (SP), Ultra Precision (UP), and operating temperature from -15°C to 80°C; it is compatible with THK QZ Lubricator. Designed for rigidity, self-adjusting capability, caged ball technology, low friction, low noise, and long maintenance intervals, this assembly supports precise, repeatable linear positioning across CNC, automation, and inspection applications.
