An automatic tensioner is crucial for maintaining correct Poly-V belt tension as it stretches over time, while all guide and accessory pulleys must spin freely. A seized tensioner or pulley bearing creates drag, causes rapid belt wear, noise, and can lead to belt derailment and accessory failure. Our product line includes reliable automatic tensioners with durable springs and dampers, along with a full range of smooth-running idler and accessory pulleys. These components are vital for a stable and efficient accessory drive system, preventing belt slippage, reducing wear, and ensuring quiet, trouble-free operation.
