Example 12" diameter Example 4" diameter Design Efficiency REALI-SLIM® Bearings Improve Design Efficiency In REALI-SLIM® bearings, each series is based on a single cross section which remains constant as the bore diameter is increased. This is in sharp contrast to standard bearings in which the cross section increases as the bore diameter increases. The constant cross section of a REALI-SLIM®...

10 | www.kaydonbearings.com 1-800-514-3066 REALI-SLIM® Bearings Catalog 300 ©KAYDON® Corporation Issue 10 Section 1–Introduction Radial and Axial (Thrust) Loads 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 1-7). 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...

It features a circular pocket separator and a 30° contact angle (see Figure 1-9) 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, Type A bearings have unidirectional thrust capacity. Thus, this bearing should be...
