The Pillow block web tension sensor STPB is a compact and reliable force measuring block designed to be installed between a pillow block bearing and the machine frame. Typically mounted under pillow-block bearings at both ends of an idler roll shaft, it directly measures the vertical load generated by web tension. This structure ensures accurate force transmission from the bearing housing while maintaining stable mechanical integration in web handling systems. With rated capacities ranging from 10 kg to 300 kg, it provides dependable performance for light to medium-duty applications requiring precise tension feedback.

As a high-performance pillow block load cell, model STPB is widely used in closed-loop tension control systems across continuous processing industries. It is commonly applied in printing, packaging, paper converting, film processing, textile manufacturing, and lithium battery production equipment. Typical installations include gravure and flexographic printing machines, slitting and rewinding systems, laminating and coating lines, film extrusion and BOPP/PET production equipment, aluminum foil processing, and textile or wire tension control. By delivering accurate real-time force measurement, the STPB helps improve web stability, reduce material waste, and maintain consistent product quality in high-speed production environments.
