Uxcell Brass Pinion Gear Set - 0.5 Mod 30T 6mm Bore Spur Gear With M3 Set Screws

Alright, gear enthusiasts and RC hobbyists, let me tell you about this uxcell Brass Pinion Gear that's seriously well-made and perfect for various mechanical projects. This is a 0.5 module gear with 30 teeth, featuring a 6mm bore size that fits standard motor shafts perfectly. The outer diameter measures 16mm across the teeth section, with an effective teeth length of 5mm - all the important specs you need to know for compatibility. What's really nice is the brass construction - it has excellent wear resistance, good strength, and handles chemical corrosion much better than cheaper materials. The teeth surface is intentionally kept soft, which actually helps with smoother engagement and reduces noise during operation. The package includes two M3 set screws, which is super convenient because you don't have to hunt for the right screws separately. Installation is straightforward - just make sure you're installing it on the flat part of your motor shaft for secure positioning. I've used these in RC cars, small robotics projects, and even some custom machinery builds, and they've held up really well under various conditions. The step design is thoughtful too - it measures 13mm in diameter by 5mm high, which gives you some flexibility in how you position the gear. The machining quality is impressive for the price - the teeth are cleanly cut, the bore is precisely sized, and there are no rough edges or imperfections. Whether you're replacing a worn-out gear in your RC vehicle or building something from scratch, this pinion gear delivers reliable performance without breaking the bank. It's one of those components that seems simple but actually makes a big difference in how smoothly your mechanical systems operate. Definitely recommended if you need a quality brass gear that won't let you down mid-project!
