This ABEC-5 bearing features deep-groove design races, with Grade 10 balls, full-contact dual-lip, labyrinth (LLU) seals facing outwards to withstand daily abuse of use and the elements, and lighter-contact LLB seals facing inwards to contain the 90% fill Mobil XHP 222 high-pressure water-proof synthetic grease. CN clearance specification is best for looser press-fit bearing bores.

Radial bearing generally used as a hub bearing, and can be used as a pivot bearing though the MAX-type version of this bearing is better suited for suspension use.
