A water pump bearing is a small but essential and powerful part of any water cooling system. Functions of the water pump bearing include: enabling a water pump to be self righting, enabling the water pump to support large axial loads and ensuring that the pump as a whole can be operated quickly and efficiently. Modern water pump bearings usually are able to rotate around 45 degrees, which means that your water pump can swivel around and bear different loads in different positions. Manufactured from tough stainless steal and other high quality materials, these water pump bearings will withstand a long period of sustained use without wearing or tarnishing: important qualities for any component that needs to stay immersed in water and bear heavy loads.
