“…29,30 The vibration statistic features such as spectrum amplitude ratio based on the fault frequencies and spectrum amplitudes has been used to identify the spall propagation and spalling damage level in bearings. 30 Bearing life has been experimentally evaluated by running the bearings till their failure 31,32 and also the L 10 fatigue life have been calculated by investigating the bearing failures based on characterization of microstructures using optical microscopes, chemical analysis, visual observation, and hardness values of the bearing components. The fatigue stress limit of the bearings has been significantly enhanced due to the advancement in manufacturing technology which permitted the production of bearing components with high precision by using high quality materials, allowing the contact stress to reach up to 1500 MPa.…”

A comparative study on fatigue life of deep groove radial ball bearings possessing conventional and micro-grooved outer races by experimental investigation is discussed in this paper. This research has been carried out to explore and understand the fatigue life of a micro-grooved ball bearing (MGB) with a circumferential micro-groove on outer race by conducting long duration tests under dry condition (i.e. wiping out the applied grease from the races by using tissue paper and lint free cloth) and compare the results with same size SKF BB1B 420206 conventional bearing (CB) at the identical operating parameters. Frictional torque (FT), bulk temperature, and overall vibration level of the test bearings (CB and MGB) at the maximum load zone have been measured at 800 N ( pH = 1.7 GPa) radial load and 1800 rpm (4.2 m/s) for the entire duration (7.8 million revolutions) of the experiments. Comparison of the surface conditions of the bearing components by means of the captured scanning electron microscope (SEM) images, roundness and deviation in profile of the races measured by co-ordinate measuring machine (CMM), and photographs captured before and after the experiment indicates lesser damage of the MGB components as compared to the conventional cases. Moreover, the initiation of fatigue failure in CBs is faster as compared to the MGBs for the same test condition, indicating longer bearing life in MGBs as compared to the CBs.

High-speed cylindrical roller bearings are critical components used in turbofan engines. The failures in the cylindrical roller bearings are common failure cases in the turbofan engines due to the tough speed and load conditions, which can increase downtime and create an enormous loss. Thus, it is necessary to understand the failure reasons including the careless handling, improper clearance or mounting, ineffective sealing, and unsuitable lubrication. This paper introduces a failure analysis of a high-speed cylindrical roller bearing used in the turbofan engine. A detailed analysis of high-speed cylindrical roller bearing failures is proposed by using the finite element method. The failure reasons are identified as the manufacturing errors in the effective length of the inner ring, which led to the high-stress concentrations at the two ends of the roller resulting in fatigue failures. The failure mechanisms are understood. The optimization design of the structure to avoid the failures is presented. The validation test shows that the prevention strategies for similar failures are addressed. This paper can provide some guidance for analyzing and identifying the spalls and wear failures in the high-speed cylindrical roller bearings used in the turbofan engines.
