Engineers, hobbyists, and repair technicians working on RC cars, 3D printers, robotics, and precision instruments rely on flanged miniature bearings to lock axial position while keeping the overall assembly compact. The integrated flange shoulder eliminates the need for additional hardware and simplifies installation in blind-bore housings.\u003c\/p\u003e\n\u003cp\u003eThis listing covers the F604ZZ through F695ZZ series — nine sizes of flange deep groove ball bearings constructed from chrome steel (GCr15) raceways with a stamped steel flange collar. Double-contact steel shields (ZZ) on both sides retain grease and block particulate ingress without adding significant drag. Inner bore diameters range from 3 mm (≈ 0.118 in) to 8 mm (≈ 0.315 in), outer diameters from 9 mm to 22 mm (≈ 0.354 in to 0.866 in), and widths from 4 mm to 7 mm (≈ 0.157 in to 0.276 in), covering the most common miniature flanged bearing sizes in a single product listing.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include flanged miniature bearings for 3D printer extruder idlers, RC car wheel hubs, drone motor mounts, small gearbox output shafts, and medical device actuators — anywhere a low-profile, self-locating bearing is required. The ZZ shield configuration makes these suitable for light-to-moderate radial loads in dry or lightly lubricated environments.\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 F6xx and F6x4\/F6x5\/F6x8 flanged bearing housings.
