THK RSR12WZM Linear Motion Ball Bearing Slide

The THK RSR12WZM Linear Motion Ball Bearing Slide is a miniature wide-type recirculating ball linear guide assembly, featuring an RSR12WZM bearing block mounted on a 390 mm stainless steel guide rail with a 12 mm rail size. The four-way equal-load design, stainless steel construction, and precision recirculating steel balls deliver smooth, low-friction travel with high rigidity in all directions and corrosion resistance. Grease lubrication compatible and capable of high-speed precision motion, it supports an infinite stroke design via ball recirculation and is built for long service life with proper lubrication. Commonly used in semiconductor processing equipment, laboratory automation, medical devices, optical inspection equipment, electronics assembly machines, and precision measuring systems, it is aimed at maintenance teams, OEM machine builders, and system integrators for repairs, retrofits, or replacement of miniature linear motion components.
