Pinion Gear 13T Mod 0.5 CNC 3.2mm Bore

The Arrma ARA-2025 Pinion Gear 13T Mod 0.5 CNC 3.2mm Bore is a precision-cut pinion designed for reliable, efficient power transfer in Mod 0.5 gear systems. Its CNC finish helps promote a smooth mesh when correctly set, supporting consistent drivetrain performance in RC models.

Suggested compatibility: Mod 0.5 spur gears and motors using a 3.2 mm shaft.

Key Details

• 13-tooth pinion gear
• Module 0.5 (Mod 0.5) pitch
• 3.2 mm bore
• CNC-machined construction
• Arrma part number: ARA-2025

As a general gearing note, a lower-tooth pinion like 13T typically favours torque and control over outright top speed. Always set gear mesh correctly and monitor motor temperatures after gearing changes to maintain performance and longevity.
