Overview
Boost your top-end speed with the Hot Racing 22T 0.5 Mod Hardened Steel Pinion Gear. Precision-machined from hardened steel with a blackened protective finish, this 22-tooth pinion is built for the rigors of high-load RC drivetrains and is the perfect choice when you want more speed from a 0.5 module gear system.
With a 1/8-inch (3.2mm) bore, this pinion is designed for motors using a 3.2mm output shaft — including the Hot Racing CSG182R08 — and pairs cleanly with 0.5 Mod spur gears. The 22-tooth count delivers noticeably higher top speed than smaller pinions, making it ideal for open-track running or top-end tuning sessions.
Key Features
- Hardened steel construction with blackened finish
- 0.5 module (Mod) tooth profile
- 22-tooth count — biased toward top-end speed
- 1/8-inch (3.2mm) bore — fits 3.2mm motor shafts
- Includes 3mm set screw for secure mounting
Performance Benefits
- Higher top-end speed compared to lower tooth counts
- Far stronger and more durable than soft stock pinions
- Precision-cut teeth for smoother, quieter gear mesh
- Long service life under heavy drivetrain loads
Usage Notes
Designed for the Hot Racing CSG182R08 motor and other motors with a 3.2mm (1/8") output shaft. Confirm spur gear pitch is also 0.5 Mod before installing. Higher pinion counts increase top speed but also motor load — monitor motor temperatures during initial runs and reduce gearing if motor heat climbs above safe limits. Apply removable thread-locker to the set screw.
