Precision grade ABEC-1, max rpm 34000 with grease. Lubricated with grease for reduced friction and no maintenance required. Single-row ball bearing designed for applications involving radial and axial loads, can be removed and reinstalled. Ideal for moderate load applications such as skateboards, inline skates, electric motors, bicycle and motorcycle wheels, and various rolling applications. Suitable for replacing worn bearings in skateboards, scooters, inline skates, electric motors, wheels, automobiles, and power tools. Please verify dimensions, size, and precision grade to ensure compatibility with your device. This 608 miniature ball bearing features red double seals and a steel cage, meeting the ABEC 1 precision standard. It has an 8 mm bore diameter, 22 mm outer diameter, and 7 mm width. Precision rated at ABEC 1 by the Annular Bearing Engineers Committee (ABEC), enabling higher speeds and lower friction compared to less-precise bearings. Internal clearance is C3, with standard CN (normal) clearance between inner and outer rings to accommodate thermal expansion. Heat-treated for increased hardness and wear resistance. Deep raceway grooves support high radial and axial loads. Straight bore design fits standard cylindrical shafts. Nylon cage prevents ball-to-ball contact, reducing friction, vibration, and noise. Removable single-lip contact seals on both sides protect against contaminants and retain factory-applied lubrication. Suitable for use in skateboarding, inline skating, and other rolling applications.
