Universal joints ("u-joints" for short) are components of the driveshaft assembly fitted to most rear-wheel drive trucks, four-wheel drive trucks and SUVs, or off-road vehicles. U-joints, which are found in pairs on the driveshaft, compensate for the height misalignment between the transmission and the rear axle, all the while transferring power to move the vehicle.

Trunnion Bearings of Grinding Mill. The trunnions are an integral part of the steel heads and are turned true with the axis of the mill. After machining, the trunnions are given a polished surface to minimize friction. The mill trunnions are carried on heavy babbitt bearings which provide ample surface to insure low bearing pressure.

For special applications trunnion bushings can be furnished constructed of Micarta to allow water lubrication or oil lubrication. In many dry grinding applications, or where heat is developed, the trunnion …
