AB Precision Planetary Gearbox

AB Precision Inline Planetary Gearbox

Home » AB Precision Planetary Gearbox

Overall:

AB series high-precision planetary gearbox with innovative design features. The integrated nut in the output planetary frame eliminates axial clearance, ensuring superior torsional rigidity and robust radial and axial load-bearing capabilities. Crafted from high-quality 40Cr steel through heat forging, the gear components exhibit heightened strength, rigidity, and toughness. With true hardened helical gears and 3D simulation design analysis, our gearbox excels in high-precision applications, frequent start-stop operations, and scenarios with load variations, offering outstanding performance and extended lifespan.

Features:

  • Frame size from 42mm to 220mm
  • Modularized designed for any servo and stepper motors
  • Backlash as low as to 3 arcmin
  • Standard Torque Capacity up to 2560N.m
  • Standard Ratio 3:1 up to 320:1
  • Any mount positions
  • Grease lubrication lifetime free-maintenance
  • Large radial and axial load capacity
