Higher Dynamic Capacity Ratings for Thin Section Bearings (Pic)

A new, more accurate method of projecting bearing life has confirmed that the ratings of many KAYDON REALI-SLIM® bearings exceed previously published figures, by five times in some cases. KAYDON® Corporation bearings are supplied in the UK by R. A. Rodriguez.



The dynamic capacity improvements for REALI-SLIM® bearings vary with type and size with increases for Type X, the four point contact bearing, ranging from 31% to 77%. As part of the validation process KAYDON® Corporation also tested several competitors’ thin-section bearings. The actual dynamic capacity of those bearings was found to be up to 72% lower than their published ratings.

The revised KAYDON® Corporation ratings are derived from a new method of calculation developed specifically for thin section bearings. It integrates theoretical projections with actual test data instead of simply estimating bearing life as is the practice of other manufacturers. The KAYDON® Corporation Bearings Division is believed to be the first thin-section bearing manufacturer to adopt this methodology.
