Cross shaft maintenance free bearing

The Cross shaft generally refers to a universal joint, which is a mechanical component used to achieve variable angle power transmission. It is used to change the position of the transmission axis direction. It is a joint component of the universal transmission device in the automotive drive system. The combination of the universal joint and the transmission shaft is called the universal joint transmission device. On vehicles with front engine rear wheel drive, the universal joint transmission device is installed between the output shaft of the transmission and the input shaft of the drive axle main reducer. On vehicles with front engine front wheel drive, the transmission shaft is omitted, and the universal joint is installed between the front axle half shaft and the wheel, which is responsible for driving and steering.
