Whether you're rebuilding a brushless motor, assembling a 3D printer carriage, or fabricating a custom RC drivetrain, the flange lip locks axial position without additional retaining hardware — eliminating the slop that causes premature wear in high-cycle assemblies.\u003c\/p\u003e\n\u003cp\u003eThese miniature flanged ball bearings feature a steel inner and outer race with metal shields on both sides, covering inner diameters from 2 mm to 10 mm (~0.079\" to ~0.394\"). The flange outer diameter extends beyond the standard OD by approximately 1–2 mm, providing a positive stop against the bore shoulder. Available sizes span ID × OD × Height × Flange OD: 2×5×2.3×6 mm, 3×6.2×2.5×7.2 mm, 4×8×3×9.2 mm, 4×9×4×10.3 mm, 5×11×5×12.5 mm, 6×13×5×15 mm, 8×16×5×18 mm, and 10×19×5×21 mm.\u003c\/p\u003e\n\u003cp\u003eTypical use cases include miniature flanged ball bearings for RC car wheel hubs, flanged bearings for 3D printer idler pulleys, and small flanged ball bearings for robotics joint pivots — all applications where axial location accuracy and low rotational drag directly affect performance.\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 Verify your bore diameter, housing shoulder depth, and shaft tolerance before ordering.

This flange acts as a built-in shoulder stop, locating the bearing axially against a housing face without needing a separate snap ring, circlip, or press-fit step.

Use a light machine grease or bearing grease appropriate for your operating temperature and speed.
