Needle roller bearings: 60 years and still evolving

Feb 21, 2013· A needle roller bearing is a bearing that uses small cylindrical rollers. These rollers are used to reduce friction of a rotating surface. Compared with ball bearings, needle roller bearings have a large surface area that is in contact with the bearing raceway journals. The typical structure of a needle roller bearing comprises an inner race

splitting tensile tests according to Guinea et al. (1994), Planas et al. (1999) and Elices et al. (2002). It was found that the bilinear softening curves approximated from the two tests successfully predicted the experimentally observed strain, strain distribution, failure loads and failure mode. Recently the ACI 446 committees collated

ROLLING BEARING FAILURES - e Longo

most prevalent rolling element bearing types are ball, cylindrical roller, spherical roller, and tapered roller. Generally sing, bearings will exhibit no signs of wear unless contaminants such as dirt, or abrasive foreign matter, get into them. Seizing is one of the most common failure modes when bearings are first put into

Abnormal Wear Mechanism and Improvement of High-Speed

Jul 26, 2021· The primary failure modes of high-speed cylindrical roller bearing under light load are the skidding of roller and the fracture of cage [1, 2]. There is a lack of research on bearing failures caused by the serious wear of roller working surface and end faces, named “abnormal wear of roller” in the paper, which cannot provide a theoretical
