Description
An extra-hard steel pinion gear for brushless RC motors, with a 5 mm bore and 18 teeth in 0.8 module. Precision-machined for a tight mesh and built for durability, it’s designed for RC cars that use a 5 mm motor shaft.
Includes one 4 mm set screw; a 2 mm Allen key is required to tighten it (not included). The gear fits 5 mm motor shafts, and a 5 mm to 1/8″ reducer sleeve is needed for 1/8″ shaft motors. It can mesh with both 32 pitch and 0.8 module gears; note that 0.8 module gears have a slightly larger outside diameter per tooth, but mixing these types generally does not add noise or wear.
