HRNSG838 - 38t Steel 48p Pinion Gear 5mm & 1/8

High‑strength 38‑tooth steel pinion gear designed for RC vehicles using 48 pitch gearing standards. Compatible with 5 mm or 1/8 in motor shafts, the precision‑machined gear provides smooth engagement with spur gears, improved durability under high‑torque conditions, and resistance to wear and deformation. 

• 38‑tooth gear profile with 48 pitch specification for compatibility with common RC spur gears.

• CNC‑machined steel construction ensures high torque tolerance and long service life.

• Fits both 5 mm and 1/8 in motor shafts with dual-bore compatibility.

• Heat‑treated surface increases wear resistance and reduces deformation under high-speed operation.

• Compatible with electric brushed or brushless motors in 1/10–1/8 scale RC cars and trucks.

• Precision tooth spacing ensures smooth mesh with spur gears and reduces drivetrain vibration.

• Lightweight design balances strength with minimal added rotational mass for improved acceleration.
