As a core component of industrial equipment, the reliability of rolling bearings directly affects the service life and operational safety of the equipment, constituting a crucial research direction in tribology. The ABLT series enhanced life testing machines demonstrate advantages including high automation, precision and reliability. The accelerated automatic rolling bearing life testing (A²BLT) and fast failure analysis system technology (F²AST) system represents an upgraded rolling bearing life and reliability accelerated testing system developed based on the ABLT series machines. This paper conducts research from three perspectives: the development of life acceleration testing and failure analysis systems; multi-source condition monitoring and intelligent fault diagnosis; and the construction of dynamic life prediction models. Centred on A²BLT and F²AST technologies, variable-load accelerated testing and rapid failure analysis are implemented through the testing machine’s hardware architecture and control systems to shorten bearing life verification cycles. A vibration-lubrication-temperature multi-parameter fusion fault diagnosis method is proposed, combining algorithms with deep learning models to enhance early detection rates for inner/outer race spalling and rolling element damage. A hybrid life prediction model integrating accelerated testing data and actual operational parameters is established to reduce prediction errors. By strengthening the application of tribological engineering technologies in bearing life and reliability engineering and enhancing the testing capabilities of industry-accredited laboratories, these efforts serve as both a crucial entry point for quality safety in the bearing industry chain and a significant driver for cultivating new productive forces and achieving high-quality development in the bearing sector.
