Kaydon Reali-Slim® open bearings

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.

Design features
Kaydon Reali-Slim® ball bearings include internal fit up, lubricants, separators, and other features that meet the most demanding specifications. Stainless steel Reali-Slim® or Endura-Slim® series of ball bearings provide exceptional corrosion resistance. Kaydon Endurakote® plating provides corrosion resistance equal to or better than an AISI 440C stainless steel bearing and can be supplied with very quick delivery.

Reali-Slim® ball bearings are available in a wide variety of separator options to space the rolling elements uniformly and prevent contact between them. Separator types include: continuous ring "snap-over pocket," continuous ring circular pocket, formed wire, toroid, PTFE spacers, and ball bearing spacer separators.

Kaydon Reali-Slim® open thin section ball bearings range in bore diameters from 0.750 inch to 40.000 inches. The seven series in the Reali-Slim® product line range from .187 x .187 inch to 1.000 x 1.000 inch in cross section. Standard 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).

In many applications, a single Reali-Slim® four-point contact radial ball bearing can replace two bearings, compacting the design and simplifying the bearing mounting while saving money, creating space, and saving weight.
