Double Pitch Roller Chains use straight link plates. And they are divided into the large roller series and the small roller series, according to the outer diameter of the rollers used. Small Roller Series (Called as S Roller Type) *Indicated by a "0" as the last digit of the chain number. *The outer diameter of the roller is the same as for the standard roller chain which it is based. *Standard sprockets can be used if they have at least 30 teeth. Large Roller Series (Called as R Roller Type) *Indicated by a "2" as the last digit of the chain number. *The outer diameter of the roller is the same as for the standard roller chain which has the same pitch as the double pitch roller chain. *Use specialized sprockets.
