It carries a dynamic load rating of 412 N and a static load rating of 784 N. Common applications include CNC routers, 3D printers, industrial automation equipment, packaging machinery, woodworking machines, and material handling systems that require reliable linear guidance on 12 mm shafts; maintenance teams and system integrators use this pillow block for repair, retrofit, expansion, and replacement in automation equipment.
