HP-551270P Chain is also known as HP55/1270/P chain and is a hollow pin conveyor chain. Primarily HP551270P chain is found in wastewater applications, food processing, chemical plants, and even refineries. The chain has become so popular due to the hollow pin design which allows for an able area for easily affixing attachments to the outer plates through the hollow pins. The attachment can be fastened tightly against the hollow pin rivet or left in a free manner to pivot.

HP-551270P Chain is typically made of stainless steel, zinc plated components, acetal copolymer rollers, or a combination of the three options based upon the application needs. The chains breaking load ratings are based upon the zinc plated version, technical data on other vacations can be supplied at the time of quoting. We also supply HP-551270P Chain sprockets and can custom manufactured desired attachments for the chain upon request.
