Description
Black Bearing bearings are "hybrid" bearings, more commonly known as "ceramic" bearings.
These bearings meet the demands of cycling (road, mountain biking, time trials, cyclo-cross, etc.) and are used for wheels, cranksets, derailleur pulleys, etc.
Product advantages:
- Weight reduction (ceramic density < steel density)
- Withstands very high speeds
- Much longer service life (several times that of a standard bearing)
- Less friction = less loss when pedaling
- Improved rigidity
- Greater precision
- Better mechanical characteristics (hardness, compressive strength, etc.)
Details:
- Dimensions: 15 x 28 x 7 mm
- Inner and outer rings made of treated stainless steel for improved mechanical strength.
- Silicon nitride balls
- Steel cage
- Specific seals: LB (better fluidity, less friction), LU (better sealing, better protection against water, mud, and dust)
- Grease specially adapted for ceramic bearings
- Sold individually
