A thrust bearing is a type of bearing specifically designed to handle axial (thrust) loads, which are forces acting parallel to the shaft's axis. Unlike radial bearings that support radial loads perpendicular to the shaft, thrust bearings are meant to support loads that are parallel to the shaft's axis, such as those encountered in rotary or linear applications where axial movement or force is present. Thrust bearings typically consist of a series of rolling elements, such as balls or rollers, housed within a raceway. The rolling elements transmit the axial load while allowing for smooth rotation or movement of the shaft. Thrust bearings come in various configurations, including ball thrust bearings, roller thrust bearings, and fluid thrust bearings, each suited for different load capacities and operating conditions. In essence, thrust bearings play a crucial role in machinery and mechanical systems where axial loads need to be supported and managed effectively to ensure smooth operation and longevity of the equipment.
