F series parallel shaft helical gear reducers are mainly used in horizontal coaxial output scenarios, with the characteristics of wide speed ratio range and large power range;
R series helical gear hardened gear reducers have various installation forms and solid shaft coaxial output, which are suitable for occasions that need to bear large axial and radial forces;
K series spiral bevel gear reducers adopt spiral bevel gear right-angle output and modular combination system design, with a wide range of motor combinations, installation forms and structural solutions;
S series hardened gear worm reducers have self-locking function and high degree of automation, which are suitable for scenarios that need to match different types of motors from 0.12KW to 22KW.
