HomeTHRUST BALL BEARING

THRUST BALL BEARING

A thrust ball bearing is a type of rolling-element bearing designed to accommodate axial loads, which are forces acting parallel to the shaft’s axis of rotation. It consists of a set of steel balls arranged in a circular raceway within a housing or washer. The raceway is typically shaped like a shallow groove, allowing the balls to roll freely.

 

The key components of a thrust ball bearing include:

Housing or Washer

This is a flat, disc-shaped component with a groove or raceway in which the steel balls roll.

Steel Balls

The balls within the bearing transmit the axial load between the two raceways. They are usually made of steel, providing strength and durability.

Cage or Retainer

The cage or retainer holds the steel balls in place, maintaining their spacing and alignment within the bearing.

Thrust ball bearings are designed to handle axial loads in one direction and cannot accommodate radial loads. They are commonly used in applications where there is a need to support axial loads, such as automotive transmissions, machine tool spindles, and thrust reversers in aircraft engines.

Thrust ball bearings come in various configurations, including single-direction and double-direction designs. Single-direction thrust ball bearings can only accommodate axial loads in one direction, while double-direction thrust ball bearings can support axial loads in both directions.
