Kaydon's 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.
Kaydon Reali-Slim® open thin section ball bearings range in bore diameters from 0.750 inch to 40.000 inches, with cross-sections ranging from .187 x .187 inch to 1.000 x 1.000 inch. Open bearings are available from stock in three configurations: angular contact bearings (type A), Conrad assembled deep groove radial ball bearings (type C), and four-point contact radial bearings (type X).
Type A - Angular contact
A deep groove bearing with reduced shoulder on one side of inner or outer race ball path. Snap-over assembly permits use of a one-piece circular pocket ring separator and greater ball complement. These Kaydon bearings will accept radial load and single direction thrust load and are normally used in conjunction with another bearing of similar construction. Type A Kaydon bearings require the application of thrust to establish contact angle. Stock bearings are individual units and when purchased as such must be adjusted at installation to desired running clearance or preload. If preferred, matched sets are available. Kaydon also offers matched spacers for applications requiring extra precision.
Type C - Radial contact
A Conrad assembled bearing designed primarily for application of radial load–deep ball grooves also permit application of thrust load in either direction – often used in conjunction with another bearing.
Type X - Four-point Contact
A Conrad assembled bearing designed for applications involving multiple loads. Unique internal geometry permits application of radial load, thrust load in either direction, and moment load, individually or in any combination. A single Kaydon four-point contact bearing may replace two bearings in many applications.
