SS Roller Chain
ANSI｜Single Pitch｜Heavy Duty
“S” type roller chains are designed to meet the requirements of greater break resistance and maximum endurance. The through hardened pins with a larger diameter than standard provide greater shock load resistance. The link plate thickness of “S” type roller chain is the same as that of the next larger sizes of corresponding pitch chain. They can fit perfectly on standard sprockets.
