Kaydon® Reali-Slim® bearings offer a wide variety of bearing solutions for even the most unique design challenges. Each Reali-Slim® ball bearing series is based on a single cross section which remains constant as the bore diameter is increased (in sharp contrast to standard bearings, in which the cross section increases as the bore diameter increases). By using the same series of Reali-Slim® bearings throughout a product line, the designer can standardize on common components.
