Planetary Gearboxes

PAB High Precision Planetary Gearboxes

  • The lowest backlash of 0-3 arcmin.
  • High torque and high dynamic.
  • High-cost performance.
  • Applicable for all servo motor and stepper motor.
  • Improve the rigidity and increase the motor rotor inertia.
  • Shorten the positioning time of starting and stopping
  • Miniaturization of motor power. At the same time, it improves the stability of inertia load and reduces the vibration.
  • The surface of the gearbox is treated with electroless Nickel, and the connection plate is treated with the blue anode to improve the tolerance and corrosion resistance of the environment.

Our company’s famous PAB series high-precision planetary gearbox adopts the integrated design of planet carrier and output shaft to ensure maximum torque rigidity and stability. Thanks to the high-cost performance of 3F’s famous PAB series planetary gearboxes, it is widely used in servo applications in the motion control industry. Our company’s famous PAB precision planetary gearbox has ample torque, and input diameter D4 can reach φ255mm, which significantly meets customer needs. A variety of backlash types can be selected according to customer needs micro precision backlash (P0), precision backlash (P1), and standard backlash (P2). Single-stage planetary gearboxes and two-stage gearboxes are available:

●First-level ratio: 3, 4, 5, 6, 7, 8, 9, 10

●Two-level ratio: 12, 15, 20, 25, 30, 35, 40, 50, 60, 70, 80, 90, 100
