1.) Light weight, small volume, Comparing with common cylindrical gear reducer, the weight of this kind of reducer is 1/2 lower, and volume is 1/2~1/3 less.

2.) High driving efficiency, The driving efficiency of 1 stage is up to 0.97, that of two stage is 0.94, that if 3 stage is 0.91.

3.) High driving power. Power can be 1 KW ~ 1300 KW.

4.) Hard tooth surface is used, and life is long, and it is widely applicable.
