Bearings with this rating were originally designed andintended for use in t
10、he 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 indeterminate shock and vibration.Therefore, whe
11、n these bearings are used in crane hook appli-cations or other similar steady pull applications, the steeringpivot rating can be doubled. It should also be kept in mind thatthese bearings were designed for oscillating or slow rotationapplications only and should never be operated at speedshigher tha
