REALI-SLIM ® Bearings Catalog 300 ©KAYDON ® Corporation Issue 10 Separator Types (continued) Formed Wire Separator Figure 4-5 PTFE Spacer Slugs Figure 4-6B Section 4–Separators, Balls, Performance When the need exists for maximum capacity and thus the greatest possible number of balls, a formed wire separator may be used to avoid the disadvantages of a full complement bearing. It has been most successfully employed in Type A bearings, where the greater number of balls can be installed without resorting to use of a loading slot. Use in bearing Types C and X should be restricted to very low speed applications. Comparatively high wear rate coupled with relatively light section can cause the wear life of the wire separator to be a limiting factor in the life a bearing, especially if the loads are high. However, where weight or space are at a premium and the added capacity is an important consideration, this separator may be considered a good compromise. A bearing with a wire separator and maximum allowable ball complement has a static load capacity of 180% of the catalog static rating. Toroid Separators Figure 4-6A Spacer Balls Figure 4-6C Helical Spring Separators Figure 4-6D In some critical positioning applications, uniformity of torque is more important than the actual mean torque level. Specially designed toroids (Figure 4-6A), PTFE spacer slugs (Figure 4-6B), spacer balls (Figure 4-6C) or helical compression springs (Figure 4-6D) have proved in a number of such instances to be satisfactory for ball separation—by their nature they give a large amount of individual and cumulative circumferential freedom to the balls. To prevent this freedom from being abused, however, speeds must be low and loads comparatively light. Applications involving use of these separators should be referred to KAYDON for review and recommendation. 96 | www.kaydonbearings.com 1-800-514-3066
