Description

TJX12RN30 is a 12mm micro planetary gearbox designed for miniature precision mechanisms. The planetary gear train uses hardened steel gears with a 30:1 reduction ratio. Backlash is minimized to <1.5° for accurate positioning. The housing is made of engineering plastic with metal output bearing for low noise and long life. We provide optional motors such as coreless DC, coin-type vibration motors, and micro stepper motors.

Wide range

Diameter 12mm, ratios 10–100:1, torque up to 0.5 Nm, backlash <1.5–2.5°.

Applications

- Medical micro pumps

- Smart locks

- Miniature robots

- Optical zoom mechanisms

Advantages

1. Smallest footprint: 12mm diameter fits in tightest spaces.

2. Precision gearing: Low backlash for positioning accuracy.

3. Low noise: Plastic carrier and optimized tooth profile.
