Chain and Sprockets
Get to know more bearing types from NYN bearing and find the right bearings you want now!
Sprockets are not Gears, Gears mesh together directly to distribute power. Sprockets are not pulleys,pulleys are smooth and pulleys utilize belts to convey power. Sprockets are used with Chain and the center distance between the two the sprockets can variety in distance. The advantage of using sprockets and chain is that slippage is not admissible. A higher degree of torque can be used with sprockets chain but slower Rpm’s. Pulleys and belts disadvantage is the slippage factor, but the components are much lighter and can run at a higher RPM. There are some HTD Belts and Pulleys that will give you both the advantage of High torque and High Rpm. Sprockets and Chain are more cost effective and very accessible power transmission options. There are a large variety of Sprockets and that can meet all different applications.
