AS6590 Needle Thrust Bearings

Needle thrust bearings are compact axial load bearing assemblies that use small cylindrical rollers (needles) to support thrust loads in a minimal axial space. These bearings feature needle rollers arranged in a circular pattern, typically with a cage to maintain proper spacing and alignment.

Common applications include automotive transmissions, gear drives, machine tool spindles, and heavy equipment where space is limited and high axial load capacity is required. They are often used in combination with radial bearings to accommodate combined loading conditions.
