Products Description

Micro Spur Pinion – Ultra Small Module Gear

MH manufacture custom small-module micro gears.

This product is an ultra-small module miniature spur gear, OD Ø8mm and L10mm, belonging to the typical miniature precision transmission component.

Achieving stable, low-noise, and low-backlash transmission within a small space.

Product Features

Ultra-small module design: m0.3, with extremely small tooth profile, requiring extremely high machining precision.
High-precision tooth profile control: DIN 6 (gear hobbing), DIN 5 (gear grinding).
High coaxiality of shaft-hole, the hole diameter is Ø2mm. The coaxiality between the tooth profile and the hole directly determines the system's operational stability.
The tooth surface Ra ≤ 0.4, making it suitable for low-noise systems.

Key Technical Challenges

The extremely fine tooth profile demands exceptionally high machining stability.

Clamping is difficult, and micro-deformation is easily introduced.

Tooth profile accuracy and hole concentricity must be controlled simultaneously.

MH Custom Micro Spur Pinion Gear Applications

Aircraft-borne actuators

Inertial navigation miniature transmission mechanisms

Radar positioning systems

Precision optoelectronic equipment

Miniature servo drive systems
