DC & TCDouble Capacity Roller Chain & Triple Capacity Roller Chain
BS｜Single Pitch｜Heavy Duty
“DC” type roller chains consist of twice the number of side plates as the single strand chain, and its working load is close to the standard double strand chain.
“DC” type and “TC” type roller chains run on standard roller chain sprockets, and the ideal chain speed is less than 50 m/min.
