I'ANCO H and C class Sprockets are available in a full range of materials including mild and alloy steel, austenitic manganese and duplex stainless steel. Both the burnt plate style, and the increasingly popular cast sprockets, are machined to fit standard pipe sizes and are available with a chain-saving tooth profile. Regardless of manufacturing style, I'ANCO ensures that the tooth location and pitch diameter are absolutely uniform so as to provide the best possible performance.
