NN120F Reducer (Gear Box)

Stepper motor/servo motor series precision reducer, which
using planetary transmission designed, superior product characteristics;
 | The structure is compatc, with the smallest size of the existing
models reducer (Gear Box)
|
 | More teeth, average load, gear meshing with the low-speed
transmission
|
 | Large Torque Transfer, Large radial-carrying capacity
|
 | Backlash small gap, the transfer of high precision
|
 | Installation is simpole, coaxial output
|
 | Little fever, lower noise; Longevity; Low price
