The bearing is primarily designed for use in advanced wheel hubs, where low rolling resistance truly comes into its own. Additionally, the 6803 size is often found in bottom brackets and certain types of pulley wheels where precision is crucial. By installing ceramic bearings for bicycles, you achieve a more direct feel for the surface as energy loss in the bearings is minimized. Whether you ride in dry dust or wet mud, the robust construction ensures that the bearing keeps performing mile after mile.\u003c\/p\u003e\u003ch3\u003eMaximum value creation with hybrid technology\u003c\/h3\u003e\u003cp\u003eWhy choose the CEMA 6803 Hybrid Ceramic Wheel Bearing - 17x26x5mm over a standard steel bearing? The answer lies in the choice of materials. Si3N4 ceramic balls are significantly harder, lighter, and rounder than traditional steel balls. This results in a surface that is almost free of microscopic irregularities, meaning less heat buildup and friction. The hybrid solution, where the balls run in races of 52100 alloy steel, provides the perfect balance between price, durability, and performance. With the CEMA 6803 Hybrid Ceramic Wheel Bearing - 17x26x5mm, you are investing in durability, as ceramics do not rust, and the double LLB seals effectively keep dirt and water out.\u003c\/p\u003e\u003ch3\u003eTechnical specifications and measurements\u003c\/h3\u003e\u003cp\u003eTo ensure that the CEMA 6803 Hybrid Ceramic Wheel Bearing - 17x26x5mm fits your setup perfectly, it is important to look at the technical details.
