9、onsFor definitions of terms used in this speci-fication, refer to ABMA Std. 1 and ISO 5593.3.2 Definitions of Terms Specific to This Standard:3.2.1 steering pivot ratingsteering pivot rating is used todetermine what size bearing is needed for a particular appli-cation. Bearings with this rating were
10、 originally designed andintended for use in the king pins of front axles on large trucks.In this application, the bearings are subject to only oscillationmotion, with a lot of shock and vibration loading. The steeringpivot rating includes a safety factor of approximately 2.0 tocompensate for the ind
11、eterminate shock and vibration. There-fore, when these bearings are used in crane hook applicationsor other similar steady pull applications, the steering pivotrating can be doubled. It should also be kept in mind that thesebearings were designed for oscillating or slow rotation appli-cations only a
12、nd should never be operated at speeds higher than5 rpm.1This specification is under the jurisdiction ofASTM Committee F34 on RollingElement Bearings and is the direct responsibility of Subcommittee F34.04 onAutomotive/Industrial Bearing.Current edition approved June 1, 2006.
