Qloi-LeUe 0.6M Hardened Steel Pinion Gear Set 23T-27T, 5mm Bore, 5PCS

About this item

• 0.6 Mod Gear for 5mm Motor Shafts: Designed for RC motors with 5mm output shafts and matching 0.6 Mod pinion gears. Please confirm your motor shaft diameter, pinion gear pitch/module, and tooth count before purchase to ensure proper fit and smooth gear mesh.
• Hardened Steel for Long-Lasting Use: Made from hardened steel for better wear resistance than many standard alloy or plastic gears. Built to handle repeated high-speed rotation and stable power transfer in RC cars, trucks, buggies, truggies, and other hobby drivetrain setups.
• Wide RC Hobby Compatibility: Fits for Traxxas Tamiya HPI HSP Redcat WLtoys 1/8 1/10 RC cars, trucks, buggies, truggies, crawlers, boats, and model airplanes using 5mm motor shafts and 0.6 Mod gears. Available in 17T-28T tooth counts and combo sets for drivetrain tuning. Please confirm gear pitch, bore size, and tooth count before ordering.
• Easy Installation with Proper Gear Mesh: Slide the pinion gear onto the compatible 5mm motor shaft, align it with the spur gear, and use a thin strip of paper between the pinion and spur to set proper gear mesh before tightening the set screw. After tightening, remove the paper and check that the gears rotate smoothly with slight clearance. Proper gear mesh helps reduce grinding noise, motor heat, and premature gear wear.
• Dual Power System Support, 5PCS Set: Compatible with mainstream 5mm-shaft brushed and brushless RC motors adopting 0.6 Mod drive standards. Each set contains 5 different tooth counts (23-27T), perfect for daily replacement, routine maintenance, gear ratio tuning and emergency backup parts storage.
