· V-belt pulleys are generally cast iron (good casting performance), and timing belt pulleys are generally cast steel or aluminum alloy.

· The transmission runs smoothly, with bass and low vibration;

· Simple structure and convenient adjustment;

· The transmission is not as strict as the meshing transmission for the manufacturing and installation accuracy of the pulley;

· With overload protection function;

· The adjustment range of the center distance between the two shafts in the transmission is relatively large.

· Pulleys are mainly used for long-distance transmission of power, such as the power output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, packaging machinery, lathes, forging machines；

In addition, there are some small horsepower motorcycle power transmission, agricultural machinery power transmission, air compressor, reducer, reducer, generator, gin, etc.
