They retain high strength at high temperatures and are used in equipment operating above 250C A major use is in high-impact sliding surfaces in aircraft landing gear Because aluminum bronze has poor compatibility embeddability and conformability it is best suited for heavy-duty low-speed applications with plentiful lubrication

Jeanna Van Rensselar Considerations for thin section

2017-6-2Generally a bearing is considered a thin section when the bore diameter is greater than four times the radial cross section The considerable advan-tage of the compact design is slightly offset by a diminished load-carrying capacity and temperature limitations in some cases The standard material is high-chrome bearing steel but they

Extend roller bearing life in high temperatures

2020-8-19Generally in high temperature applications if the oil or grease used has a lower viscosity the bearing system will fail prematurely As can be expected generally in a high temperature application a higher viscosity oil or grease should be used Figure 10 shows oil viscosity vs temperature

High Speed Bearing Technologies for Wastewater

2020-8-19High speed bearing technology is applicable for aeration blowers operating at much higher speeds than the typical 60Hz 3600RPM for cast multistage units High Speed Turbo (HST) units are usually single stage (though some utilize multiple cores) and rotate from 15 000 to 50 000RPM

Bearing Considerations for High

2020-8-19Find the Right Bearings for Your Applications Like many types of bearing failure overheating is avoidable when you choose the right product for your applications High-temperature bearings allow your applications to operate as they should in extreme environments saving you from spending time and money on costly maintenance and repairs

Plant Engineering

Thermal stability oxidation resistance and temperature limitations must be considered when selecting greases for high-temperature applications In non-relubricatable applications highly refined mineral oils or chemically stable synthetic fluids are required as the oil component of greases for operation at temperatures above 121 C (250 F)
