John King Chains

American Standard Engineered Steel without Rollers

The smooth and stable flow of material through a process depends on the performance of the conveyor chain installed within the equipment. Bush class chains or steel knuckle chain are of the same construction as roller conveyor chain, but with the roller excluded. This series, with a reduced number of components, has proved to be particularly successful in high duty, high abrasion applications where lubrication is not possible. For many years KING steel bush chains have been proving performance in mill duty centrifugal discharge elevators within the more difficult applications encountered in the Cement and Steel Industry.
