Low-noise chain

Global standards on environmental noise are forcing factory owners and equipment operators to explore inexpensive and effective ways to quiet drive chains. One potential solution is U.S. Tsubaki's low-noise chains drive. They have the strength and reliability of the company's ANSI standard chains, but reduce noise levels nearly 50% by using a spring roller that absorbs the impact of sprocket-chain interactions. Available in sizes 40 through 80, the U.S. Tsubaki, Wheeling, Ill., the chain meets environmental-management standards such as ISO 14000. The chains exceed ANSI minimum tensile strength requirements, operates with standard sprockets, and works at temperatures ranging from 14 to 140°F.
