Engineers, machinists, and serious DIYers working on pumps, gearboxes, rotary tables, and vertical shaft assemblies need a thrust bearing that holds its geometry under load — and resists corrosion in demanding environments. These stainless steel thrust ball bearings are built for exactly that.\u003c\/p\u003e\n\u003cp\u003eEach bearing in the 51100–51110 series is a three-part assembly: a shaft washer, a housing washer, and a ball-and-cage assembly. Available in 304 Stainless Steel (excellent general corrosion resistance) and 440 Stainless Steel (higher hardness, suitable for moderate corrosive environments). Inner diameter (ID) ranges from 10 mm (0.39 in) to 50 mm (1.97 in); outer diameter (OD) ranges from 24 mm (0.94 in) to 70 mm (2.76 in); thickness ranges from 9 mm (0.35 in) to 14 mm (0.55 in).\u003c\/p\u003e\n\u003cp\u003eTypical use cases include vertical shaft thrust load management in water pumps and centrifugal equipment, rotary table and indexing fixture assemblies requiring low-friction axial support, and light-duty gearbox or motor end-thrust applications where stainless corrosion resistance is required over standard carbon steel bearings.\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 51100–51110 series shaft and housing dimensions.
