... was tested in contact with an En31 steel lower ball, and this increased the time of failure to 70 s. Wear properties of silicon nitride in dry rolling-sliding contact were studied using a ring-on-roller test machine ( Ref 52 ). Under no lubrication and a maximum Hertzian pressure of 1.1 GPa (0.16 × 10 6...

.... Testing of Rolling Bearings From the 1910s to about 1945, bearing testing was primarily based on the use of test machines designed and built by the bearing manufacturer and in some universities. Enough information developed in this time period for a symposium on the testing of bearings ( Ref 19...
