HRNSG11M15 - 11t Mod 1.5 Hardened Steel Pinion Gear 8mm Bore

Hardened steel pinion gear with an 11‑tooth, 1.5 module tooth profile and an 8 mm bore. It’s built to mesh precisely with matching 1.5 mod spur gears in RC electric drivetrains, offering strong abrasion resistance and consistent power transfer under high torque conditions. Precision‑cut gear teeth help maintain accurate gear engagement and reduce drivetrain lash and noise.

• hardened steel construction improves strength and wear resistance compared with stock gear materials

• 11‑tooth 1.5 mod tooth profile fits compatible Mod 1.5 spur gear systems

• 8 mm bore matches common large‑scale and 1/8 scale motor shafts

• precision machining maintains accurate gear mesh and reduces drivetrain noise

• balanced gear design supports smoother power transfer and reduced vibration

• suitable for high‑torque and high‑load motor setups

• direct replacement for OEM 1.5 mod pinion gears in compatible RC drivetrains
