Ninja Bearings feature steel construction with a black coating to help resist wear and extend lifespan. Made for the industry standard 608 bearing bore in wheels, these bearings are built for performance and easy maintenance. The removable rubber shield allows for easy cleaning and maintenance while greatly reducing friction and eliminating the annoying rattling noise from regular metal shields. High-speed nylon ball retainers generate less friction than traditional metal retainers, helping you maintain forward momentum better while also eliminating rattle and reducing the risk of rust. Packed with PRO Ultimate + Speed Lubricant, Ninja Bearings are race-ready right out of the box. **Using these bearings with the EVO Spacer System is not recommended, as it may apply excessive pressure and generate heat that can cause the bearings to seize.
