Engineers, machinists, and serious DIYers working on lathes, rotary tables, automotive steering columns, and industrial machinery need axial ball thrust bearings that hold their geometry under sustained load — without play, noise, or early fatigue.\u003c\/p\u003e\n\u003cp\u003eThese axial ball thrust bearings are constructed with a hardened steel ball complement seated between two grooved washers (shaft washer and housing washer), conforming to the 511xx and 512xx series dimensional standards. Inner diameters span 10mm to 150mm (approx. 0.39\" to 5.91\"), with outer diameters from 24mm to 190mm (approx. 0.94\" to 7.48\") and thicknesses from 9mm to 31mm (approx. 0.35\" to 1.22\"), covering the full 51100–51320 range.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include: single-direction axial load support on vertical shaft assemblies such as crane hooks and jack screws; rotary table and indexing fixture preloading in CNC and manual machining setups; automotive steering column and gearbox thrust positioning where compact axial footprint is critical.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"hdiy-compat\"\u003e\n\u003cspan class=\"hdiy-compat-icon\"\u003e🔩\u003c\/span\u003e \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits standard 511xx and 512xx series shaft and housing seats.
