Set include one 0.5 modulus 4MM Hole Dia brass gear shaft and one 60 T brass worm gear wheel.
The transmission structure of worm shaft is simple, compact, small volume and light weight.
Shaft Z1=1, turn a round of gear T, can get a large transmission ratio, generally in the power transmission, the transmission ratio I=10-80, like big transmission ratio, if use with gear transmission, will need to take the multi-stage transmission.
High quality material selection, carefully processing create high quality product.
Made of brass, long time service.
