Get PriceThe axial load carrying capacity of angular contact ball bearings increases as the contact angle increases. The contact angle is defined as the angle between the line joining the points of contact of the ball and the raceways in the radial plane, along which the combined load is transmitted from one raceway to another, and a line perpendicular to the bearing axis ( fig. 1 ).
Get Price2018-3-1 · For starved-oil or solid lubrication of high-speed instrument angular contact ball bearings, friction heating and wear are the main reasons of bearing failures. This paper presents a dynamic wear simulation model to investigate the impacts of different preload methods and the changes of preload caused by wear on bearing wear life.
Get PriceProblems such as misalignment, unbalance, looseness and friction are all telegraphed through the bearing, sometimes leading to failure. And since bearings are often the most important machinery components, failure can result in costly downtime, damage to adjacent parts and significant repair costs.
