2903 Thrust Ball Bearing | Single Direction Axial Load

Thrust ball bearings are designed to support axial loads in one direction while allowing rotation between two surfaces. They consist of two washers (raceways) with a ball and cage assembly positioned between them, providing efficient load distribution perpendicular to the shaft axis.

These bearings are commonly used in automotive transmissions, marine propeller shafts, machine tool spindles, and rotating platforms where space is limited and pure axial loads must be accommodated. They require proper mounting on flat, rigid surfaces to achieve optimal performance and service life.
