Description Technical Specs
20BDC double capacity roller chain is a high-strength 1.25" pitch chain that can operate on BS/ ISO single-strand sprockets with roughly double the tensile and working capacity as a standard 20B-1 roller chain. This unique chain is designed with double the amount of side plates and an enlarged pin giving it strength capabilities almost on par with a leaf chain with the flexibility of a roller chain. 20B double-capacity chain boasts an average ultimate tensile strength of 47,660 pounds with a tremendous dimensional-to-strength form factor of only 2.38" at its widest point (the connecting link)! What sets our 20B double-capacity chains apart from others is the use of top-grade material grades, special high-shock pins, wide-waste link plates, precision heat-treated components, shot-peened components, a specific factory pre-load, and solid round parts (bushings & rollers). Combining these processes, features, and premium raw materials results in a double-capacity roller chain that is highly capable and durable. We typically supply 20BDC chains in lengths of 10ft, including one connecting link, but alternative lengths are available upon request.
