AST Vice President of Operations, John Wallace, recently had an article published in Machine Design magazine. Titled “Three Life-Changing Environments for Bearings,” it addresses the basics of bearing life, plus operating in high-temperature, corrosive and vacuum environments.
The life of a bearing depends upon the environment in which it functions, including size, loads, speeds and duty cycles. High-temperature environments can damage bearings by reducing lubricant viscosity, resulting in bleed-out and decreased longevity. This can be solved by using solid lubricants or surface coatings, according to Wallace.
Corrosive environments typically call for stainless steel bearings, sometimes protected by seals that retain lubricant and exclude moisture and chemicals. Vacuum environments need protection from contamination, requiring bearings that are ultra-clean without volatile residues that can outgas.
The industry knowledge and expertise reflected in this article are the most important components of AST’s value-added services.
