“…Likewise, the data for CVM AISI M-50 reported in the author's Fig. 1 are consistent with similar data obtained in the NASA five-ball fatigue tester (Zaretsky et al, 1982). This would suggest differences in either manufacturing processes or material quality between the batches of hot-pressed silicon nitride tested by Baumgartner et al (1973) and Parker et al (1974).…”

“…Specimen geometry from flat rollers, curved rollers and spherical rollers to spherical rollers-and-conical wedge is used to simulate the working conditions of final application [1][2][3][4][5][6]. Loading on the rollers is by dead weight with or without leverage, spring, pneumatic, and hydraulic system.…”

“…Several types of testers have been commonly applied to evaluating the RCF of bearing balls. They include Four-Ball-Rolling tester [1] , Five-Ball-Rolling tester [2] , V-Groove/Ball tester [3] , and Rolling-Element-on-Flat tester [4] . These RCF testers work in rolling/sliding conditions.…”

A newly developed pure rolling fatigue test rig with three contact points for bearing balls was used to perform rolling contact fatigue (RCF) tests. The fatigue properties of GCr15 steel balls and two kinds of Si3N4 ceramic balls produced with different technologies were compared. Ball surfaces were examined after failure with optical microscope and scanning electron microscope (SEM). It was identified by tests that the failure mode of ceramic balls was surface spall. The main factor of ceramic ball failure was principal tensile stress. Life tests data, summarized in accordance with the Weibull theory, showed that the life of GSN-200 balls was close to that of GCr15 balls, whereas the life of NBD-200 balls was much longer than those of . Under the same working condition, the temperature rise of all ceramic balls was lower than that of steel balls, and their crack propagation rates were slower than that of steel balls.
