Micro Gears Collection

It adopts a small module (M0.2) and 16-tooth optimized profile to deliver stable torque, low backlash, smooth meshing, and long service life in high-frequency, high-precision motion scenarios.This pinion gear is widely used in robot finger drive mechanisms, joint reduction systems, micro-actuators, and bionic robot motion components.

This pinion gear is widely used in robot finger drive mechanisms, joint reduction systems, micro-actuators, and bionic robot motion components.

Key Performance Overview

This precision drive pinion is engineered to balance ultra-compact structure with stable torque transmission for miniature robotic transmission systems.It maintains excellent reliability, low noise, and consistent motion accuracy even under high-frequency reciprocating motion, rapid start-stop cycles, and long-duration operation-making it ideal for the high-dynamic working conditions of humanoid robot joints and fingers.

Why 16 Teeth Matters

The 16-tooth (Z16) design is carefully optimized for miniature robot transmission:

Provides smoother tooth engagement than smaller pinions (Z10–Z14), reducing impact and vibration.
Improves meshing stability and positioning accuracy for precise finger movement.
Reduces surface contact stress, lowering wear and extending service life.
Enhances torque uniformity during low-speed, high-precision rotation.
Supports micro-step positioning required for dexterous robot hand control.
