This article outlines points to consider when specifying bearings for challenging environments, to ensure high reliability and excellent long-life performance of equipment.
A bearing system comprises many elements, including balls, rings, cages and lubrication. Standard bearings do not typically stand up to the rigours of harsh environments, so the individual parts require special consideration. The most important elements are lubrication, materials, and special heat treatment or coatings.
Operating at high temperature
High-temperature applications, such as those used in actuation systems within the aerospace industry, can present challenges for standard bearings. Furthermore, temperatures are rising in equipment as units become increasingly smaller and have increased power-density, which poses a problem for the average bearing.
