Universal joint bearing, refers to the use of spherical connection to achieve different coaxial power transmission of the mechanical structure, is a very important parts of automotive bearings.
Classification of universal joint bearings: Constant velocity universal thrust ball bearing joint ball cage type universal joint triple pin type universal bearing joint double mill type universal joint etc.
Universal joint consists of spider(cross) and 4 grease-filled roller bearings. It can transmit large torque at low friction. Spider with journal pegs and bearing cases as outer ring were hot forged or cold formed and machined. They are later carburized in furnace so that increased ruggedness and wear resisitance are obtained. Parts are finally ground to designed size under severe tolerance. Oil seal as well as dust cover are also in use to protect internal journal area from intrusion of foreign material. Variety of grades and materials are selected to repond to extreme conditions such as very hot / very cold temperatures.
