Black bearing bearing ceramic 17 × 28 × 7 mm B5 17287-2RS UB-17287-C

BLACKBEARING Ceramic Hybrid 17287-2RS Bearing – 17 × 28 × 7 mm

EAN: 3760290193390
SKU: UB-17287-C
Brand: BLACKBEARING
Type: Hybrid Ceramic Deep Groove Ball Bearing (2RS)

The BLACKBEARING UB-17287-C is a premium-quality hybrid ceramic bearing designed for high-performance cycling applications. The 17287-2RS bearing has dimensions of 17 × 28 × 7 mm and is suitable for precision rotating components where low friction, smooth operation, and long durability are required.

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

The double 2RS rubber sealing system effectively protects the bearing against dust, moisture, and contamination while maintaining the lubricant inside for smooth and reliable operation.
