In addition to use on plant machinery and farm equipment, HKK chains are found in the lumber, mining, oil, food processing, packaging, construction and many other industries. The basic function of HKK roller chains is the transmission of mechanical power with a high degree of efficiency. By using HKK chains, you can eliminate power loss and down time while being sure of profitable, high level production. HKK roller chains are manufactured to meet our own tough standards, well exceeding American National Standard Institute standards. HKK chains are dimensionally interchangeable with any other chains conforming to ANSI standards.
