608-2RS Skateboard Bearing, 8x22x7, Sealed, Pack of 100, ABEC 1 Precision, Nylon Cage

This 608-2RS miniature radial ball bearing is designed for optimal performance in demanding applications. Measuring 8 mm in bore diameter and 22 mm in outside diameter, with a width of 7 mm, this bearing is engineered to handle both radial and axial loads effectively.

Crafted to conform to the ABEC 1 precision standard, this bearing allows for higher speeds while maintaining lower friction compared to less precise alternatives. The ABEC 1 rating, established by the Annular Bearings Engineers Committee, ensures that this bearing performs within a narrow range of variation, making it an excellent choice for various projects, including skateboarding and inline skating.

The 608-2RS bearing is made from through-hardened 52100 bearing quality steel, which provides optimum wear resistance. This material is heat treated to enhance its hardness, ensuring durability in high-stress applications. The deep ball grooves in both races are designed to support high radial and axial loads, making this bearing versatile for multiple uses.

One of the standout features of this bearing is its nylon cage, which evenly spaces the balls within the bearing. This design minimizes friction, vibration, and noise during operation, leading to a smoother, quieter performance. Additionally, the removable single lip contact seals located on both sides of the bearing protect against contaminants, ensuring that the lubrication applied during manufacture remains intact for longer periods.

Rolling bearings like the 608-2RS utilize rolling elements to maintain separation between moving parts, significantly reducing rotational friction. These elements can include a variety of shapes, such as balls, cylindrical, spherical, barrel, needle, spindle, or tapered designs. In this case, the 608-2RS features ball elements, which are known for their excellent load-bearing capabilities.

Sealed bearings, such as the 608-2RS, come pre-lubricated with oil or grease at the factory, providing immediate functionality out of the box. In contrast, open and shielded bearings require lubrication in place and periodic maintenance. The seals play a critical role in protecting the internal components of the bearing from environmental debris, which could otherwise compromise the bearing’s speed and lifespan.

This ball bearing is not only suitable for skateboarding and inline skating but also finds application in various other fields, such as robotics, agricultural machinery, elevators, and more. Its reliability and performance make it an essential component in equipment that ranges from dental tools to aggregate crushers.

In summary, the 608-2RS skateboard bearing is a superior choice for anyone seeking a reliable, high-performance bearing. Its combination of precise engineering, durable materials, and user-friendly features ensures that it meets the rigorous demands of both casual users and professionals alike. Whether you are upgrading your skateboard, building a custom device, or simply need a dependable bearing for a project, the 608-2RS will exceed your expectations.
