Whether you are rebuilding a small gearbox, assembling a rotary table, or replacing a worn thrust element in a power tool, selecting the wrong thickness or bore diameter means the whole assembly runs rough or fails early.\u003c\/p\u003e\n\u003cp\u003eThese plane axial ball bearing thrust bearings follow the metric F-series designation, covering bore diameters from 2 mm (approx. 0.079 in) up to 12 mm (approx. 0.472 in), outer diameters from 6 mm to 23 mm, and thicknesses from 3 mm to 7.5 mm. Each unit consists of a ball complement retained between two hardened steel washers (shaft washer and housing washer), forming a compact flat-profile thrust assembly.\u003c\/p\u003e\n\u003cp\u003eTypical applications include light-duty axial positioning in RC vehicle differentials, 3D printer Z-axis lead screw supports, small lathe tailstock spindles, and hand-tool pivot assemblies where radial space is limited but axial stiffness is required.\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 Note:\u003c\/strong\u003e These are metric F-series thrust bearings.

For example, F8-16M has an 8 mm bore and a 16 mm OD. Measure your shaft diameter for the ID and your housing seat for the OD, then match to the closest model.

For most applications, apply a thin layer of appropriate bearing grease or oil to both raceway faces before installation.

Ensure both mating faces are clean, flat, and free of burrs. Apply light lubrication to both raceway faces.
