A Magnetic Dome bearing is a type of bearing found in the pump of complete water cooling kits. Its purpose is to ensure the smooth and quiet operation of the pump's rotating part, known as the impeller. The operating principle relies on a combination of magnetic force and a single dome-shaped contact point. The magnet levitates the impeller, significantly reducing friction and wear. The dome-shaped contact point, referred to as the 'dome', then ensures stability and effective lubricant distribution. The result is a reduction in pump vibrations and operating noise, as well as an extension of its lifespan.
