907 cast chain is apart of the 900-class pintle chain class. This chain is typically found in the sugar industry and it is extremely durable, high-strength, and high quality. These chains are manufactured with reinforced links where wear is greatest during operation of the intermediate conveyors. The pin heads are T-shaped to prevent rotation, and the bushings are press fit for greater life. For optimum abrasion and corrosion resistance, the links can be manufactured in 300 grade stainless steel. The pins and bushings can be supplied in 400 grade stainless steel, which is heat-treated to avoid premature wear.
