Uxcell 100 Pcs 3/32 Inch Ceramic Bearing Balls - Silicon Nitride Si3N4 Precision G10 Balls For Aerospace & Robotics

Need some seriously tough little balls for a project? These uxcell ceramic bearing balls are made from silicon nitride (Si3N4), which is crazy hard, won't rust, and handles high heat like a champ. You get 100 pieces, each 3/32 inch in diameter with a G10 precision rating—super consistent in size. They're self-lubricating, so they spin smoothly with less friction and noise, perfect for high-speed applications. Use them in bearings for RC cars, drones, industrial machinery, or even robotics projects. They're wear-resistant, which means your stuff will last longer and need less maintenance. Whether you're tinkering in the garage or working on aerospace components, these little black spheres are up for the job. Just be careful not to drop them—they like to bounce and roll away!
