Notre avis

Antoine B.

Technology specialist

Discover the high-end performance delivered by BlackBearing B5 ceramic ball wheel hub bearings 6903-2RS. Lighter in weight, they allow you to optimise your wheels while providing better handling at very high speeds, a longer service life (several times that of a standard bearing), less friction, greater rigidity, greater precision and better mechanical characteristics.
To ensure that these bearings are compatible with your wheels, remove the bearings installed in your hubs and measure the various dimensions with a calliper.

Features

- Inner and outer rings made of treated steel
- Silicon nitride balls
- Steel cage
- Low-friction 2RS seals: water and dust resistant
- Grease specially adapted for ceramic bearings
- Internal diameter: 17 mm
- External diameter: 30 mm
- Thickness: 7 mm
- Reference: 6903-2RS, 61903-2RS

Bearing sold individually.
