Reali-Slim ® thin-section bearings havecontributed to reductions in weight and size inthousands of applications since we introducedthem over 45 years ago. The engineeringdrawings reproduced in this booklet arerepresentative samples of the many differentways Reali-Slim ® bearings have been used tosimplify designs, reduce weight and/or size,and cut manufacturing costs in a variety ofapplications. We hope these illustrated ideastarters will help you do the same.For additional information about Reali-Slim ®thin-section bearings, call us toll-free, 1-800-514-3066.© 2005 Kaydon Corporation

How to use Reali-Slim ® bearingsfor more design flexibility.Reali-Slim ® bearings let you replace a smallsolid shaft (king post), as shown below, witha larger diameter hollow shaft. This gives youthe freedom to run air and hydraulic lines, orelectrical wiring and slip rings through theshaft, as shown on opposite page.Traditional DesignTypical solid-shaft (king post) designusing two conventional bearings.Overweight, expensive, and bulky.Limits design options.

How to use Reali-Slim ® bearingsfor more design flexibility.A large bore, small cross-section Reali-Slim ®bearing permits the use of a large diameterhollow shaft in place of a smaller solid shaft.Components such as air and hydraulic linesor electrical wiring and slip rings can thenbe accommodated within the hollow shaft,resulting in a neater, more efficient design.▼In many applications, a single 4-point contactReali-Slim ® bearing can replace two bearings,compacting the design and simplifying the bearingmounting. Besides the obvious cost savings ofeliminating one bearing, this arrangement alsocontributes further savings in weight and space.▼KAYDON CORPORATIONLIGHT WEIGHT, COMPACT DESIGNSBEARINGSUSEDREALI-SLIM ® THIN-SECTIONIMPROVED DESIGN #1
