Kaydon Reali-Slim® stainless steel bearings

At Kaydon, we apply engineering experience and expertise to solve the world's most unique bearing challenges. When an application calls for a high precision, ultra-clean thin section bearing to operate in close proximity to corrosive chemicals, and with lubricants that don't protect against corrosion, Kaydon Reali-Slim® stainless steel bearings are the ideal solution.

Kaydon AISI 440C stainless steel bearings meet the minimum 58 HRC hardness level and can support the same loading as 52100 chrome steel. Balls are available in stainless steel or ceramic.

Reali-Slim® stainless steel thin section bearings minimize the surface degradation and particulate formation so commonly found in harsh environments. Kaydon Reali-Slim® stainless steel thin section bearings are available:

  • in AISI 440C stainless steel races
  • with brass or non-metallic separators
  • with stainless steel or ceramic balls
  • in popular sizes
  • in either radial contact (C), angular contact (A), or four-point contact (X) configurations

Design features
Each Reali-Slim® stainless steel ball bearing series is based on a single cross section which remains constant as the bore diameter increases. By using the same Reali-Slim® series throughout a product line, the designer can standardize on common components.

Reali-Slim® bearings include internal fit up, lubricants, separators, and other features that meet the most demanding specifications.

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

Kaydon Reali-Slim® stainless steel open thin section ball bearings range in bore diameters from 0.750 inch to 40.000 inches and from 0.187 x 0.187 inch to 1.000 x 1.000 inch in cross section. Open bearings are available 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® stainless steel 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.
