This paper presents the results of an extensive experimental investigation into the performance of a short multi-grooved bearing subjected to a range of static and alternating loads. Lubricating oil was supplied, at pressures of up to 2000 lb/in ² , to capillary type restrictors connected to 10 closed-end axial grooves in the bearing. The bearing h...

Two dynamically loaded testing machines are described. These testing machines utilize a balanced pressure piston for the detection of tensile stresses in the oil film, and a test bearing housing mounted in an externally pressurized bearing for the measurement of bearing friction. Oil film pressure surveys indicate areas of general cavitation preced...

... Opitz [3] investigated both theoretically and experimentally the effect of fluid compressibility in the recess volume. Purely experimental investigations have been reported by Patrick and Chen [4]. Theoretical and experimental investigations are also reported by Davies and Leonard [5][6] for bearings with short axial and circumferential lands. ...
