Diamond Series | Special Cleanance Roller Chain

Diamond Chain produces two types of chains designed specifically to allow for the lateral deviations that standard roller chain can't handle.

Power Curve Roller Chain

Diamond Power Curve chain is manufactured with a pin that is both smaller in diameter and slightly longer than in the pin in standard ASME/ANSI roller chain. This modification to the design allows for extra clearance between both the pin and the pushing allowing the chain to flex from side to side.

Tuf-Flex Roller Chain

Diamond's Tuf-Flex roller chain is designed for shaft or sprocket misalignment. Tuf-Flex chain can handle up to four inches of lateral displacement in every four feet of chain length and up to eight degrees of axial twist. Tuf-Flex provides extra durability and unusual flexibility to meet the strenuous service demanded of heavy-duty construction machinery.
