Premium Products Reali-Slim® Thin Section Bearings How Reali-Slim® bearings outperform other thin section bearings There are many reasons to choose Reali-Slim® bearings (see other side), but none is more critical than Performance. Design engineers know they can count on a Reali-Slim bearing not just to do its job well, but to do it longer than other bearings. In side-by-side tests, Reali-Slim bearings consistently outperform other thin section bearings. In the series shown here, three competitors’ bearings failed within 24 hours while the Kaydon bearings ran for up to 120 hours — more than five times longer. 76.0 Bearing Fatigue Life (in hours) Each test applied approximately 60% of a bearing’s dynamic radial load rating to samples at a testing speed of 1,780 rpm. For comparability, each bearing had a 4-inch bore. (Competitors’ bearings were obtained through distribution channels.) Each test continued until automatic shut-off (150% of baseline vibration level) or until audible noise indicated possible bearing failure, then disassembled and inspected for spalling. After all were run to failure, the elapsed times were entered into Kaydon’s Weibull analysis software to determine the fatigue life.

Why Reali-Slim® bearings? Every Reali-Slim bearing is designed to meet or exceed specific application requirements, then manufactured with processes and materials that assure precision and long life. Details are in the Kaydon white paper, "Not All Thin Section Bearings Are Created Equal," developed from 2009 papers presented at ASTM and ASME/STLE technical conferences and reviewed by those organizations.* For a copy, scan the code below.
