| listen hear that it s the sound of increased productivity and a better work environment it s the sound of u.s tsubaki low noise drive chain noise is everywhere turn to the person next to you and say a few words your sound level around 65 db take a stroll on any busy city street noise level more than 70 db walk into a plant running standard roller chain noise levels can top out at close to 85 db with chain running at 492 feet/min now enter a plant running u.s tsubaki low noise drive chain you ll notice a difference immediately noise levels are significantly lower up to 10 db lower than standard roller chain the decibel scale is logarithmic not linear so those 10 db are perceived as almost 50 percent less noise this chain is engineered for quiet long-lasting operation the secret to this remarkable innovation is our unique spring roller construction which provides the power and function of roller chain yet absorbs the impact of the sprocketchain interaction lower impact means les
