Black bearing bearing ceramic 10 × 19 × 5 mm B5 6800-2RS UB-6800-CS

BLACKBEARING Ceramic Hybrid 6800-2RS Bearing – 10 × 19 × 5 mm

EAN: 3760290193437
SKU: UB-6800-CS
Brand: BLACKBEARING
Type: Hybrid Ceramic Deep Groove Ball Bearing (2RS)

The BLACKBEARING UB-6800-CS is a premium-quality hybrid ceramic bearing designed for high-performance cycling applications. The 6800-2RS bearing has dimensions of 10 × 19 × 5 mm and is developed for precision rotating components where low friction, smooth operation, and long service life are essential.

The hybrid construction combines steel races with silicon nitride (Si₃N₄) ceramic balls, providing reduced rolling resistance, improved efficiency, increased wear resistance, and extended service life compared to conventional steel bearings.

The double 2RS rubber sealing system provides effective protection against dust, moisture, and contamination while keeping the lubricant inside the bearing for smooth and reliable operation.
