Precision Ceramic Double Row Ball Bearings For Bike Repair
✔️ 17x26x7mm sealed Si3N4 ceramic angular contact bearing unit

This single hybrid ceramic bearing slots straight into bicycle crank spindles. You will drop it into worn pedal hubs whenever your chain feels sloppy. The double row layout shares load across both inner and outer raceways. Your legs push harder because less energy gets lost to friction. Standard sealing keeps water out during muddy weekend rides.

✅ Stainless steel rollers sit inside a lightweight polymer cage
✅ Precision ground races reduce drag on steep climbs
✅ Direct dimension match swaps cleanly into vintage bike frames
✅ Tight machining tolerances stop side shake during hard sprints
✅ Sealed edges lock factory grease inside for quiet operation

💡 How do hybrid ceramic angular contact bearings improve drivetrain performance over time?
Switching to advanced race materials cuts rolling resistance right away.
- Si3N4 ceramic shells block road grime while keeping rotation light
