The SPARK Hard Pinion Gear O-Type delivers an incredibly durable mechanical interface at the primary high-stress point of your AEG's motor drive train. Manufactured in Japan by AIRSOFT97 as a factory-standard component on their premium INAZUMA motor series, this precision-cut pinion gear features a carefully engineered tooth engagement angle designed to suppress loud gear-shriek while smoothly transferring high rotational torque to your bevel gear. This component serves two crucial engineering purposes:
  1. Acoustic Optimization: The revised tooth geometry perfectly meshes with Tokyo Marui-spec bevels and major overseas gear sets, vastly reducing harsh motor vibrations and gearbox noise.
  2. Wear Resistance: Built with a highly fortified structural profile, it resists aggressive surface erosion, making it a reliable upgrade choice when rebuilding premium setups utilizing high-end EG-1000, EG-30000, or heavy-draw Samarium Cobalt motor systems.

Technical Specifications:

  • Material: Hardened, high-density tempered steel alloy with superior wear resistance
  • Shaft Profile Compatibility: Precision O-Type shaft hole designed for round motor shafts
  • Package Contents: 1x Hard Pinion Gear (O-Type)
  • Compatibility: Fully compatible with Tokyo Marui motor profiles, aftermarket high-torque/high-speed upgrade motors, and standard Version 2 and Version 3 gearbox gear trains
  • Origin: 100% Made in Japan
  • Design: Friction-locked interference fitment optimized for high-speed rotational tracking
Tech & Safety Warning: Installation requires a professional airsoft motor pinion gear puller/remover tool. Forcing fitment onto mismatched shafts can cause shaft bending or component fracturing. Uniquely shaped overseas D-type motor shafts are explicitly incompatible.
