Product catalog summary
Introduction
The REalI-SlIM® Bearings Catalog 300 by KaYDoN® Corporation provides detailed information on the Reali-Slim mm™ metric series bearings, which have been adapted from inch sizes to metric dimensions for specific applications.
Specifications
The Reali-Slim mm™ series includes bearings with cross sections of 8, 13, and 20mm, and bore diameters from 20mm to 360mm. Customization options include ceramic balls, special lubricants, and integral seals.
Product Features
These bearings are designed for dimensional interchangeability and offer similar options as standard REalI-SlIM® bearings. The catalog includes a selection table with dimensions, capacities, and weights for each bearing type.
Selection Tables
Detailed tables for 8mm, 13mm, and 20mm series bearings list dimensions, radial and axial capacities, and approximate weights. Static and dynamic capacities are based on 1 million revolutions of L10 life.
Identification and Customization
Reali-Slim mm™ bearings are identified by a 9- or 10-digit part number, indicating materials, size, type, separator type, and precision. Custom bearings have a 9-digit number and cannot be identified by code.
Contact Information
For further customization and specific performance data, customers should consult KaYDoN engineering or their representative. Contact details for KaYDoN Corporation in Muskegon, Michigan, are provided.
Conclusion
The REalI-SlIM® Bearings Catalog 300 is a comprehensive resource for selecting and customizing thin-section bearings, offering detailed specifications and customization options.
Overview
This document is a catalog from KaYDoN Corporation detailing the specifications of their REalI-SlIM® Bearings, focusing on the 8mm, 13mm, and 20mm series. It includes detailed tables of dimensions, capacities, and weights for various bearing models.
Specifications
The catalog provides comprehensive specifications for each bearing model, including bore size, outside diameter, land diameters (L1 and L2), static and dynamic radial and axial capacities, moment capacities, and approximate weight, all in millimeters.
Key Parameters
Radial and Axial Capacities: Provided for both static and dynamic conditions, indicating the load the bearings can handle. Moment Capacity: Indicates the torque the bearing can withstand. Weight: The approximate weight of each bearing is listed, crucial for weight-sensitive applications.
Design Features
Four-Point Contact Type X: Handles radial, axial, and moment loads simultaneously. Snapover Separator: Uses 5/32" balls for the 8mm series, 1/4" balls for the 13mm series, and 3/8" balls for the 20mm series. Chamfered Corners: Corners are chamfered to clear the maximum shaft or housing fillet radius, denoted as "F".
Additional Notes
Capacities listed are not simultaneous; for combined loading, a discussion of bearing selection and load analysis is recommended. Dynamic capacities are based on 1 million revolutions of L10 life. Static capacities are non-brinell limits based on rigid support from the shaft and housing. For hybrid series bearings (P, X, and Y), contact KaYDoN product engineering for specific values.
Contact Information
For lead time and minimum purchase requirements, customers are advised to contact KaYDoN directly.

©KAYDON® Corporation Issue 10 REALI-SLIM® Bearings Catalog 300 KAYDON created the thin-section bearing standard of the industry in 1954 based on inch sizes.  The REALI-SLIM® inch-standard bearing is still the most widely used thin-section bearing in the world. However, for those applications that require metric envelope dimensions or for dimensional inter­ changeability with other products, KAYDON offers the REALI-SLIM MM™ series of bearings. These bearings are offered: • n cross sections of 8, 13, and 20mm i • ith bore diameters ranging from 20mm to 360mm w • ith many of the same options found on standard w REALI-SLIM® bearings The REALI-SLIM MM™ series may also be customized for special applications with options such as: • eramic balls c • pecial lubes s • ntegral seals i Consult Kaydon engineering or your Kaydon representative for details on customization.
