 Thrust Ball Bearings, thrust ball bearings at the one-way and two-way thrust ball bearings, bearings, can take a one-way direction of the axial load, the bearings can withstand two two-way directions of axial loads, and both can not afford a radial load. Thrust ball bearings to be at work in the axial top tight, bearing mainly applicable to such vehicle steering mechanism, machine tool spindle, rubber and plastics machinery. Thrust ball bearing can handle loads in the axial direction only. Bearing rings mounted on the shaft are called shaft washers, while those mounted in the housing are called housing washers. Both washers contain raceways for the balls. Thrust ball bearings are available as both single bi-directional types. The bi-directional thrust bearing incorporates a third washer and an additional set of balls. The center washer is located in axial direction by a shaft shoulder and sleeve. The trust ball bearings are Available in two designs: single direction and double direction.A ball thrust bearing is a particular type of rotary ball bearing. Like other ball bearings, they permit rotation between parts, but they are designed to support a high axial load while doing this (parallel to the shaft). Higher speed applications require oil lubrication. Generally, they are composed of two washers (raceways) which may be grooved the rolling balls elements which are typically caged. As opposed to roller thrust bearings, ball thrust bearings can generally operate at higher speeds but at lower loads.Thrust bearings are commonly used in automotive, marine, and aerospace applications. They are also used in the main and tail rotor blade grips of RC (radio controlled) helicopters.Thrust bearings are used in cars because the forward gears in modern car gearboxes use helical gears which, while aiding in smoothness and noise reduction, cause axial forces that need to be dealt with.
