Extra Hard Steel Pinion Gear 5mm Bore Mod0.8 22T (RRP8722)

Extra-hard steel pinion gear for brushless RC motors, designed to deliver durable, precise gear engagement in a typical drivetrain. It features a 5mm bore, a 0.8 module, and 22 teeth to fit common 5mm shaft setups.

Made from high-carbon steel and precision machined, it is stamped with the tooth count for easy identification. The package includes a 4mm set screw; a 2mm Allen key is required for installation and is not included. It fits 5mm motor shafts and can be used with 32 pitch or 0.8 module gears without added noise or wear, though 0.8 module gears have a slightly larger outside diameter per tooth (about 0.00027 inches). For 1/8" shaft motors, a reducer sleeve is required.
