THRUST BALL BEARINGS
A thrust bearing is a typical rotary rolling-element bearing. This bearings permits rotation between parts but are designed to support a predominant axial load. The varieties of thrust bearings are Thrust Ball Bearings Cylindrical Thrust Roller Bearings Taper Roller Thrust Bearings Spherical Toller Thrust Bearing Fluid Bearings and Magnetic Bearings.
In most cases it is seen that the Thrust Bearings are generally used in cars as the forward gears in modern car gearboxes use helical gears which boosts the smoothness and curtails unnecessary noise. This causes axial forces and needs to be dealt with. Apart from this Thrust Bearings are also used with radio antenna masts to cut down load on an antenna rotator. A significant citation of Thrust Bearing in an automobile is the clutch "throw out" bearing also known as the clutch release bearing.
