NB series helical precision planetary reducer    


Product Overview:

Shanghai Guzuo Reducer (Taiwan Nuohong Precision Gear) specializes in the production and sales of precision planetary reducers. The planetary reducer is mainly used with servo motors / stepper motors to increase the output torque and increase the moment of inertia. Can also

be equipped with DC motors, single-phase motors, synchronous motors and various three-phase asynchronous motors.

    The best features of Guzo NB series helical planetary reducer are high precision and large

transmission torque. The internal design of the planetary gear structure, special heat

treatment of high-performance alloy steel, flanges and other high-strength aluminum alloy

materials, with beautiful appearance, small size, light weight, high torque, low noise, high

efficiency, long life and so on.

    NB series helical planetary reducer body is fully enclosed, protection grade IP65, filled with high-performance grease inside, lifetime lubrication and maintenance-free for life.
