Are bearings making you spin your wheels? - Ind

By: Ian A. Rubin The industry of wheels turn on bearings, so why do the wheels often vibrate, clatter, squeak, drag and overheat? Bearings can fail for lots of reasons. Most failures (as shown in Figure 1) are related to lubrication and contamination, but myths and misconceptions handed fromwheel bearings, one generation of maintenance engineers […]
