【Precision 3x6x2.5mm Micro Size】These miniature ball bearings measure 3mm inner diameter, 6mm outer diameter, and 2.5mm thickness (MR63-ZZ). Their compact size makes them perfect for precision projects where space is at a premium, such as 3D printers, quadcopters, and scale models.
【Double Metal Shielded Design】Featuring a double shielded (ZZ) design, these micro bearings effectively protect against dust, debris, and contaminants from entering the raceway. This extends bearing service life, retains internal lubricant, and ensures smooth operation in various environments.
【High-Quality Bearing Steel Construction】Crafted from high-quality bearing steel, these deep groove ball bearings offer excellent hardness, wear resistance, and durability. They are built to handle significant radial and axial loads with minimal noise for long-lasting, reliable performance.
【Smooth Operation for High-Speed Applications】Manufactured with precision engineering and lower tolerances, these MR63 bearings ensure smoother rotation, reduced friction, and consistent operation. Ideal for electric motors, small gearboxes, fans, and other high-speed or precision mechanisms.
【Versatile 10-Piece Set for Multiple Projects】This 10-piece bearing set provides ample quantity for various DIY, hobby, and repair applications. Widely used in RC cars, drones, skateboards, home appliances, garden tools, and small machinery—offering a compact and efficient solution for countless mechanical needs.
