Hybrid Ceramic Ball Bearing 6902-2RS, 15mm x 28mm x 7mm, Silicon Nitride, Chrome Steel Ring

Elevate your cycling performance with this precision-engineered 6902 2RS hybrid ceramic ball bearing. Featuring a robust 15mm inner diameter, 28mm outer diameter, and 7mm width, this bearing combines chrome steel rings with advanced silicon nitride ceramic balls. The dual rubber seals protect against debris while maintaining smooth operation. The nylon cage and pre-applied grease ensure reliable performance. These hybrid bearings offer exceptional advantages - they're lighter than traditional bearings and demonstrate superior resistance to wear and abrasion. The unique combination of ceramic balls and steel rings makes these bearings particularly well-suited for high-performance cycling applications where traditional steel bearings might not meet demands. Perfect for serious cyclists looking to upgrade their bike's bearing system with a high-performance solution.
