Precision grade ABEC-1, max rpm 34000 with grease. Pre-lubricated with grease for reduced friction and no maintenance required. Single-row radial ball bearing designed to support radial and axial loads. Easily removed and reinstalled. Ideal for moderate load applications such as skateboards, inline skates, scooters, electric motors, bicycle and motorcycle wheels, electric hand tools, and various rolling applications. Replace worn bearings in skateboards, scooters, inline skates, electric motors, wheels, automobiles, and power tools. Verify dimensions, size, and precision grade for compatibility with your device. The 608-2RS miniature radial ball bearing features red double seals and a steel cage, meeting the ABEC 1 precision standard. This light-duty bearing has an 8 mm bore diameter, 22 mm outside diameter, and 7 mm width. ABEC 1 rating provides higher speed capability and lower friction compared to less precise bearings. Radial internal clearance is C3, meaning greater clearance between inner and outer rings than standard (CN) to accommodate thermal expansion. Heat-treated for increased hardness and wear resistance. Deep ball grooves in both inner and outer races support high radial and axial loads. Straight bore fits standard cylindrical shafts. Nylon cage prevents ball-to-ball contact, reducing friction, vibration, and noise. Single lip contact seals on both sides protect against contaminants and retain factory-applied lubrication. Suitable for skateboarding, inline skating, and other rolling applications. Color: Silver + Black. Material: Carbon Steel. Size: 8 x 22 x 7 mm. Package includes 50 x 608-2RS C3 bearings.
