Engineering and selection guide Kaydon bearing solutions Precision Reali-Slim® thin section bearings (replaces Kaydon Catalog 300)

Reali-Slim… for compact, lightweight designs of the future Many years ago, Kaydon engineers trying to help designers fit assemblies into smaller spaces had an idea: what if the bearing cross-section didn’t increase as the bore size got bigger? This led them to develop new bearings with a cross-section that remained constant: Reali-Slim thin section bearings. Reali-Slim bearings produce larger ratios of diameter to radial section, which lead to space and weight savings of up to Industrial Machinery • Machine tools • Navigation, target acquistion pods • Helicopter swash plates and gearboxes •...

Kaydon makes it easy to design with Reali-Slim bearing ® As comprehensive as each new edition of this catalog is, it’s just one of many tools developed by Kaydon bearings to help engineers evaluate thin section bearings for their applications. At our website www.kaydonbearings.com, for example, you’ll find CAD downloads, an interactive bearing selector and advanced design software to make your job much easier. CAD downloads CAD drawings are available for download in 38 different formats (e.g., AutoCAD, DXF, SolidWorks). Simply select the type of bearing you want from the drop-down menu and...

Interactive bearing selector Kaydon’s interactive bearing selector lets you search our online catalog and download 2D or 3D drawings to simplify the selection process. Search by part number (even if it’s incomplete) or by bore size, outside diameter, and/or width minimums and maximums… in inches or millimeters. Reali-Design® and Reali-Design MM® When Kaydon introduced it in 1994, Reali-Design software quickly became the go-to program for anyone thinking about specifying thin section bearings. This innovative program has saved engineers countless hours by doing complex power transmission...

Product line overview The inch family of Reali-Slim thin section bearings includes seven open series (Figure 1-2) and five sealed series (Figure 1-3), ranging in bore diameters from 1.000 inch to 40.000 inches. Series range from .187 x .187 inch to 1.000 x 1.000 inch in cross-section. Open bearings are available from stock in three configurations (Types A, C & X). Stock sealed bearings are available in Types C & X only. We can provide internal fit up, lubricants, separators and other features to meet the most demanding specifications. To obtain corrosion resistance consider using the Kaydon...

Product line overview For all diameters of this rotary table your bearing envelope stays the same. Additional advantages in application design made possible by Reali-Slim bearings can be seen by referring to Figures 1-6, 1-7, and 1-8. A large bore, small cross-section Reali-Slim bearing permits the use of a large diameter hollow shaft (Figure 1-7) in place of a smaller diameter solid shaft (Figure 1-6), king-post design. Components such as air and hydraulic lines or electrical wiring and slip rings can then be accommodated within the hollow shaft, resulting in a neater, more efficient...
