Black-bearing Black Bearing Ceramic Bearing 6800-2RS 10 X 19 X 5 Mm

Black Bearing bearings are “hybrid” bearings, more commonly referred to as “ceramic”.
These bearings meet the constraints of cycling (Road, MTB, CLM, Cyclo Cross …) and are used for wheels, crankset, derailleur rollers …

The + products:

• Weight saving (density of ceramic <that of steel)
• Held at very high speeds
• Much longer lifespan (several times that of a standard)
• Less friction = less pedaling losses
• Better rigidity
• Better precision
• Better mechanical characteristic (hardness, compressive strength, etc.)

Details:

• Dimensions: 10 x 19 x 5 mm
• Inner and outer rings in treated stainless steel for better mechanical resistance.
• Silicon nitride balls
• Steel cage
• Specific low friction seals for water and dust tightness (2RS)
• Grease specially adapted for ceramic bearings
• Sold individually
