Extra Hard Steel Pinion Gear 5mm Bore Mod0.8 13T (RRP8713)

Extra-hard pinion gear for brushless RC motors, built from high-carbon steel for long-lasting durability. This 5mm-bore, 0.8-module pinion has 13 teeth and is precision machined, stamped with the tooth count for quick identification. A 4mm set screw is included, and a 2mm Allen wrench is needed for installation (not included). It fits motors with a 5mm shaft, and for 1/8-inch shaft motors a 5mm to 1/8-inch reducer sleeve is required.

Note on compatibility: 32-pitch and 0.8-module gears can be used together with no adverse effects such as increased noise or wear, though 0.8-module gears have a slightly larger outside diameter per tooth (about 0.00027 inches). This pinion delivers a durable, precise mesh for RC cars, offering dependable performance and compatibility with a range of gear sets.
