This Tsubaki RS50-2C sprocket has hubs on both sides and teeth for double-strand RS50 roller chain. Double-strand chain increases power capacity, and double hubs give secure mounting for heavier loads. It is used in conveyors and industrial drives requiring reliable power transmission. The pilot bore can be machined to the shaft size required.
