Engineers, machinists, and serious DIYers working on lathes, rotary tables, automotive steering columns, and industrial machinery need a thrust ball bearing that seats cleanly and holds up under continuous one-directional load. The 51100–51107 series is the go-to solution for bore sizes ranging from 10mm to 35mm (approximately 0.39 in to 1.38 in).\u003c\/p\u003e\n\u003cp\u003eEach bearing in this series consists of two hardened steel washers (shaft washer and housing washer) and a steel ball-and-cage assembly. The bore diameter spans 10mm (51100) through 35mm (51107), with outer diameters ranging from 24mm to 52mm and a uniform 9mm height across the series. All components are manufactured to standard dimensional tolerances compatible with ISO 10 \/ ABEC 1 class fits.\u003c\/p\u003e\n\u003cp\u003eTypical applications include: replacing worn thrust bearings in lathe spindle assemblies, supporting axial loads in rotary indexing fixtures, and serving as replacement thrust bearings in automotive steering and suspension components. Long-tail use cases include DIY go-kart axle builds, CNC router Z-axis leadscrew support, and shop-built arbor press upgrades.\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 shaft bore sizes 10mm, 12mm, 15mm, 17mm, 20mm, 25mm, 30mm, and 35mm.
