HRCSG1212 - 12t 32p Hardened Steel Pinion Gear 1/8 Bore

This 12‑tooth 32 pitch pinion gear is machined from hardened steel and heat treated to resist wear and fatigue in high‑load RC drivetrain applications. The 1/8 inch (3.175 mm) bore fits directly onto standard 1/8 size motor shafts used in many 1/8 and larger 1/10 electric vehicles, providing solid engagement with matching 32 DP spur gears. The precision tooth profile ensures smooth meshing and consistent power transfer, whether tuning for torque or top speed. A set screw secures the gear to the motor shaft, allowing straightforward installation and reliable retention under load. Compact face width minimizes interference with motor housings and helps maintain proper mesh spacing. Hardened steel construction stands up well to frequent use with metal or plastic spur gears. This part is ideal for replacing worn parts or adjusting gear ratios as part of tuning your vehicle’s performance.
