6803 Full Ceramic ZrO2 Zirconia Ball Bearings 17X26X5mm Oilless Rust Proof Zero Grease Needed Top Shelf Precision For Drones R C Cars And Skateboard Projects

Precision 6803 ceramic zirconia race bearings for rc builds
✔️ 17x26x5mm full oxide design runs dry with zero lubricant needs

This listing covers a single high performance radial bearing sized 17 by 26 by 5 millimeters. These units swap out standard steel rollers in drone motors rc chassis wheels and skateboard axles. They keep tight tolerances while shedding extra weight off rotating assemblies.

✅ Pure zincate free zirconia rings handle heavy duty thrust loads reliably
✅ Tight machining specs allow slide on mounts without spacer shims
✅ Oxide shell blocks moisture pickup for indoor storage ease
✅ Smooth rolling action cuts drag on high rev racing setups

💡 What makes fully ceramic bearings handy for custom drone builds? Builders rely on them to keep motor temps low during extended flights. - Heat resistant oxides stop thermal expansion near hot windings - Non magnetic shells skip electrical noise that trips flight controllers - Light weight rims shave grams off total airframe lift requirements
