Reali-Slim Bearings Catalog 300 Kaydon Bearings 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 85 Industrial Machinery percent. Such savings typically have a ripple...

Product Line Overview Reali-Slim Bearings Catalog 300 Kaydon Bearings 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 crosssection. 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...

Product Line Overview (continued) Kaydon Bearings Reali-Slim Bearings Catalog 300 Reali-Slim Bearings Make a More Compact Design Figure 1-5 Example 30" diameter 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...

Reali-Slim Bearings Catalog 300 Kaydon Bearings Reali-Slim Bearing Types Support All Load Scenarios Radial and Axial (Thrust) Loads Types of Reali-Slim Bearings Bearings support a shaft or housing to permit their free motion about an axis of rotation. Load can be applied to bearings in either of two basic directions (Figure 1-9). Radial loads act at right angles to the shaft (bearing’s axis of rotation). Axial (thrust) acts parallel to the axis of rotation. When these loads are offset from either the bearing axis (distance St) or radial plane (distance Sr), a resulting moment load (M) will be...

Reali-Slim Bearing Types Support All Load Scenarios (continued) Kaydon Bearings Reali-Slim Bearings Catalog 300 Angular Contact Bearing (Type A) The Type A bearing is also a conventional design. It features a circular pocket separator and a 30° contact angle (see Figure 1-11) along with approximately 67% of a full complement of balls. The chief benefit of the Type A bearing is that it provides greater thrust capacity than a Type C or Type X bearing. Because of its counterbored outer race, a Type A bearing has unidirectional thrust capacity. Thus, this bearing should be mounted opposed to another...
