Products Description
MH's small module gears offer long-term stability and consistent batch production, suitable for transmission solutions in high-precision systems.
Custom-Tailored Precision---We manufacture custom-made products based on customer design drawings to meet highly personalized needs.
What are small module gears?
Small module gears = precision gears with a module m ≤ 0.5 (or even m ≤ 0.3).
- Characteristics:
Extremely small tooth dimensions and close tooth pitch
Accumulated errors are easily amplified
Extremely sensitive to surface roughness
High difficulty in controlling transmission noise and vibration
- Widely used in:
Aerospace actuators
Inertial navigation systems (INS)
Radar scanning and positioning systems
Precision optoelectronic and measuring equipment

Why Choose MH small module gears
Lorem ipsum dolor, sit amet consectetur adipisicing elit.

know deep of small module gears
Tooth profile is highly susceptible to distortion
Cumulative error control is difficult
Surface quality directly determines lifespan
Batch consistency is hard to reach
Material advantage
Titanium, nickel-based... aerospace materials are self-supplied;
non-self-produced materials are strictly controlled;
so, material supply is stable and controllable.

Lean Manufacturing and Quality Control
Every production stage is precisely planned to prevent the accumulation of any errors during production.
The precision and performance of each batch of miniature gears are completely consistent, ensuring the long-term stable operation of each product.

Technical Consulting and Customization
We welcome you to provide drawings or key parameters (module m, number of teeth Z, outer diameter, thickness, material, heat treatment requirements). We can assist in optimizing the structure and manufacturing plan to achieve the best balance between performance and cost.
