Engineers, hobbyists, and repair technicians working on RC cars, 3D printers, robotics arms, and small machinery need a flanged solution that self-locates and resists axial displacement — that's exactly what these miniature flange deep groove ball bearings deliver.\u003c\/p\u003e\n\u003cp\u003eEach pack contains 10 pieces of the same size, manufactured from bearing steel with double-shielded (ZZ) construction to keep lubricant in and contaminants out. The flange outer diameter (D1) extends beyond the standard outer diameter (D), providing a positive stop against the housing face. Available bore sizes (d) range from 3 mm (0.12 in) to 20 mm (0.79 in), with outer diameters (D) from 7 mm (0.28 in) to 32 mm (1.26 in) and widths (B) from 3 mm to 7 mm — select your exact size from the variant options above.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include: replacing worn flanged bearings in \u003cstrong\u003eRC car wheel hubs and gearboxes\u003c\/strong\u003e where axial retention is critical; upgrading \u003cstrong\u003e3D printer extruder idler pulleys and Z-axis lead screw supports\u003c\/strong\u003e that require a compact, self-locating bearing; and servicing \u003cstrong\u003esmall electric motors, fans, and spindle assemblies\u003c\/strong\u003e in industrial and hobby CNC equipment where miniature flanged deep groove ball bearings reduce assembly time and improve concentricity.\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 flanged bearing housings.
