G3TS-20 is a short, ultra-thin harmonic gear (strain wave gear) for designs where axial space is tight. Its hollow structure lets cables, air lines or shafts pass through the center, and its zero-play tooth engagement keeps backlash within 20 arc-seconds. It is a good fit for robot joints, rotary tables, small positioners and any precision axis that needs a high ratio in a compact, single stage. Supplied and supported by Robot3T, with engineering help to integrate it into your design.

Typical applications

  • Robot joints: collaborative and light industrial arms, SCARA and delta wrists.
  • Rotary tables and indexers: precise positioning with high holding torque.
  • Welding positioners and turntables: smooth, repeatable rotation of the workpiece.
  • Automation equipment: pick-and-place heads, inspection stages, camera gimbals.
  • Research and education: robotics projects and custom actuator development.

Why G3TS-20

  • Super thin and compact – shortened design saves axial length in joints and actuators.
  • Hollow structure – route cables, tubes or shafts through the center for a clean design.
  • High load capacity – up to 95 Nm peak torque at ratio 100.
  • High positioning accuracy – backlash max 20 arcsec for repeatable motion.
  • Three ratios in one size – 50, 80 or 100 to balance speed and torque.

Frequently asked questions

Which ratio should I choose?
Ratio 100 gives the most torque and the finest resolution; ratio 50 gives higher output speed. Tell us your load, speed and motor and we will recommend one.

Can you supply it with a motor, encoder and brake as a complete joint?
Yes. We can match G3TS-20 with a servo motor and driver, or build a complete robot joint module for your project.

Can you modify the flanges or hollow bore?
For volume orders, custom flange and interface designs are possible. Send us your drawing or requirements.

Do you ship outside Vietnam?
Yes. Contact sales@robot3t.com for a quote including shipping to your country.

Designing a robot joint or precision axis?

G3T-11 is an ultra-compact, thin harmonic gear (strain wave gear) for small designs where every millimetre counts. Its hollow structure lets cables, air lines or shafts pass through the center, and its zero-play tooth engagement keeps backlash within 20 arc-seconds. It is a good fit for robot wrists, grippers, camera gimbals, small actuators and any precision axis that needs a high ratio in a tiny, single stage. Supplied and supported by Robot3T, with engineering help to integrate it into your design.
