The HKK Aqua Series single strand, double pitch, carrier type roller chain is made of carbon steel with a corrosion resistant finish and is suitable for a broad range of outdoor and seawater environments. The chain is manufactured to be corrosion-resistant while maintaining strength and durability. Its bushings and rollers are manufactured of cold-forged solid steel construction, minimizing elongation and wear caused by friction, thereby extending the life of the chain. One connecting link is included for 10’ and 20’ chains and 30’ and longer includes one connecting link per 10’ of chain. HKK’s solid roller and bushing manufacturing process minimizes distortion under heavy loads and helps prevent foreign material from accumulating under the rollers, minimizing downtime and replacement costs. The chain’s bushings, rollers, and link plates are shot peened to reduce fatigue and resist adverse environmental conditions caused by temperature, dust, and moisture. The Double Pitch roller chain has a pitch (distance between roller centers) that is twice that of a single-pitch roller chain, resulting in lower weight and operating cost than a comparable chain of the same strength. It is well-suited for slow- to moderate-speed drives and long-center shafts. Carrier-type chains are used in conveyor assemblies. This Aqua Series roller chain performed approximately 10 times better than nickel-plated counterparts in salt-water immersion tests, lasting more than 600 hours before corroding, compared with 48 hours for nickel-plated chains. The chain is flat grey in color and is supplied fully lubricated. It meets American National Standards Institute (ANSI) B29.1 standard and is dimensionally interchangeable with other chains conforming to ANSI standards. Aqua Series chains should not be used in applications where the chain may come in contact with food. Roller chains are commonly used as a power transmission component and are composed of four parts: plate, roller, bushing, and pin. A series of cylindrical rollers are held together by side links, which fit together into a toothed wheel called a sprocket. Connecting links are used to join the two ends of the chain together to form a loop. Roller chains range from simple, mechanical drives such as bicycle chains, to complex power transmission products that drive conveyors and other industrial machinery, such as printing presses and farm equipment. HKK Chain manufactures roller chain for use in a variety of industries, including agriculture, mining, and construction. The company, founded in 1916 and headquartered in Pine Brook, NJ, makes its products in a company-owned facility in Tokyo.
