LABORATORY STUDY OF THE PERFORMANCE OF STABILIZED JOURNAL BEARINGS WITH INCREASED COLLAR THICKNESS

A laboratory program was set up to study the performance of Hi-Hat and flat back bearings with increased collar dimensions when assembled with wedges of the present standard dimensions. Each bearing-wedge combination was run four days using a procedure developed for and normally used to study bearing performance. Operating a Hi-Hat or flat back bearing with the collar dimension increased by 1/8 in. in combination with the respective present standard wedge did not affect the performance on the AAR's full-scale machine.
