Silver bearings are an essential component in many types of engines. With their high temperatures and continuous functioning, engines require a stronger type of bearing than other machinery.
When steel ball bearings are electroplated with silver, they become stronger than any other type of bearing. Jet engines, for example, rely on silver bearings because they can function continuously and at very high temperatures.
Placing a layer of silver between the steel ball bearing and its housing reduces friction between the two, increasing the performance and longevity of the engine. Despite high internal temperatures, silver-coated bearings provide superior performance and a critical margin of safety for engines. Even in the event of an oil pump failure, silver-plated bearings provide enough lubrication to allow a safe engine shutdown before more serious damage can occur.
