Ratio 50:1 Nema 34 Planetary Gearbox Speed Reducer Gear Head Gearbox

• HIGH TORQUE & RIGIDITY: Designed to maximize output torque while reducing motor speed. Ideal for heavy-load applications such as linear actuators, gantry systems, and packaging machinery. 86mm square flange fully compatible with standard NEMA34 stepper and servo motors. Reduction box frame size: 3.38*3.38 inch (86x86 mm).
• UNIVERSAL COMPATIBILITY: Gear Ratio: 50 :1. Rated load (N.M): 50Nm, Maximum load (N.M): 80Nm. Gear reduction box output shaft: 16mm(0.63 inch); gear reducer input shaft: 14mm( 0.55 inch).
• PRECISION & LOW BACKLASH: Engineered with precision-ground gears and heat-treated steel, this NEMA34 planetary gearbox delivers ≤25 arcmin backlash. Ensures high repeatability and positioning accuracy for CNC mills, 3D printers, and pick-and-place robots.
• WIDE APPLICATION: Planetary gear is a good solution in applications that need low rotation speeds and/or lots of huge torque. It is mainly used to reduce the speed of the 86mm stepper motor, widely working on mill, lathe, bench, and bandsaw machines.
• SMOOTH & QUIET OPERATION: Low noise - less than 45dB. Protection Class: IP65. Helical gear design (86mm Planetary Gearbox) provides smoother engagement and lower noise compared to straight-cut gears. Operating temperature remains low even under continuous duty cycles.
