** Thrust ratings are listed for the standard and heavy thrust bearings operating continuously at the most unfavorable conditions of ratio and speed. Higher thrust loads are allowed for intermittent service for momentary load conditions. Contact the factory for an exact bearing life calculation and the most economical thrust bearing selection.
