Hardened Steel Pinion Gear 5mm Bore 48P 27T (RRP2027)

Precision-machined hardened steel pinion gear for RC powertrains. This 27-tooth, 48-pitch pinion features a 5 mm bore and is machined for precise tooth engagement, designed to mesh with compatible 48-pitch spur gears and efficiently transfer power from the motor to the drivetrain.

Built for durability, the hardened steel construction resists wear under high torque, helping maintain accurate gear mesh and long-lasting performance. The machined finish and 5 mm shaft bore simplify installation on motors, making it easy to tailor gear ratios for the right balance of speed and torque in electric models.
