Key Features & Benefits

Ultra-Micro Integrated Design:

One-piece machining of two m0.3 module gears (18-tooth outer, 12-tooth inner) with 15mm overall length, perfect for ultra-compact transmission systems where space is critical.

Aerospace-Grade Precision (ISO 5 ~ ISO 6):

Tooth profile error controlled within 0.003~0.006mm, coaxiality ≤ 0.002mm, and radial runout ≤ 0.005mm-achieved via Gleason 350GMS and high-precision CMM inspection.

High Rigidity & Miniaturization:

Crafted from high-performance alloy steel with specialized heat treatment, Nitriding etc., ensuring superior rigidity despite its ultra-small size, avoiding deformation during high-speed operation.
