Bearing Cw 15x28x7 Mm Hub Bearings. BEARING HUB 15x28x7 MM BLACK COATED New range of bearings with black coating treatment.The bearing rings are treated with this coating before assembly, which guarantees greater corrosion resistance for the component.The rings are treated on the raceway to ensure that this 'coating´ also covers the rolling surface of the ball.RINGS, BALLS AND CAGE IN 100 Cr6 STEEL:This steel is specifically designed for the production of components, has good hardenability and is ideal for applications requiring good wear and compression resistance.SPECIFIC L21 GREASE:For this range, we have selected a grease that is perfectly suited to bicycle applications.It guarantees excellent lubrication of the bearing and has a very low viscosity level, which allows for low friction and excellent smoothness.DOUBLE SEAL LUB:This bearing has two seals of different types and colours.On one side, there is a strong contact seal (LU) made of black NBR material to be mounted on the outside.The strong contact of the seal works to cover the bearing from external contamination such as dust, water and other agents.On the other side of the bearing is a light contact seal (LB).Also made of NBR material and blue in colour, this seal serves to ensure the smoothness of the bearing while still providing dust protection. tradeinn Bikeinn
