NO. 3024/ELARGE SIZE TAPERED ROLLER BEARINGS EA TypeA newly developed special heat treatment allows these bearings to ensure longer operating lifeunder severe operating conditions!!FeaturesApplication ExampleEA bearings have a particularly strong advantage by providinglonger operating life due to their improved crack fatigue strength,wear strength and peeling resistance characteristics, especiallywhen the lubricant is contaminated, but also under clean lubricantconditions. Accordingly, these bearings can be used in mining andore processing applications where marginal lubrication, vibrationsand impact loads often exist. The EA bearings provide advantagesdue to their compact design, longer operating life, and longerintervals between maintenance and inspections. EA materialtreatment can be offered in tapered roller, cylindrical roller andspherical roller bearings.Compound layerof carburized andnitrided materialsCarburized layerCoreFront wheel of dunp truck7
