HRNSG17M15 - 17t Mod 1.5 Hardened Steel Pinion Gear 8mm Bore

Hardened steel pinion gear with a 17‑tooth, 1.5 mod tooth profile and 8 mm bore designed for RC electric drivetrains that use Mod 1.5 gearing. The gear provides reliable torque transfer and consistent mesh with compatible spur gears, reducing wear and drivetrain lash under load. Precision cut teeth and hardened construction help maintain smooth power delivery in high‑torque applications.

• hardened steel construction improves durability and wear resistance versus softer alloy gears

• 17‑tooth Mod 1.5 profile meshes precisely with matching Mod 1.5 spur gears

• 8 mm bore fits standard RC motor shaft sizes for common large‑scale and 1/8 scale applications

• precision machined teeth maintain accurate gear mesh and reduce noise

• suitable for higher‑torque motors and aggressive driving conditions

• balanced gear profile supports smooth power transfer and reduced vibration

• direct replacement for stock pinion gears in compatible Mod 1.5 gear systems
