Upgrade your RC car's performance with these high-speed hybrid ceramic bearings. The size is 5x11x4mm (inner diameter x outer diameter x width), and they're built with chrome steel races (52100 steel) and silicon nitride (Si3N4) ceramic balls. The ceramic balls are lighter, harder, and smoother than steel, which means less friction, lower operating temperature, and faster spin-up. They come with metal shields to keep dirt out and grease in. These bearings are designed for clutch applications in many popular RC models – they're compatible with parts from Traxxas, Arrma, Losi, HPI, Tamiya, Team Associated, and more (check the list in the description). They're precision-made (ABEC 5 equivalent), so they run true and reduce vibration. Whether you're racing or bashing, these bearings can help your drivetrain spin more freely, potentially giving you better acceleration and top speed. They're sold as a 2-pack. Just make sure they match your model's part numbers before ordering. Give your RC a smooth, fast advantage!
