AS130170 Needle Thrust Bearings

Needle thrust bearings are compact axial bearings that use cylindrical rollers with a length-to-diameter ratio of at least 3:1 to support thrust loads in a minimal axial space. These bearings typically consist of needle roller and cage assemblies with or without washers, designed for applications where axial space is limited.

Common applications include automotive transmissions, gear boxes, pump assemblies, and machine tool spindles where thrust loads must be carried in confined spaces. They are particularly suited for high-speed rotation and applications requiring low friction and precise axial guidance.
