1.Made of brass, long time service.
2.0.5 modulus , 20 T wheel, 5mm bore gear shaft
3.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.
