Consider Figure Q4 Below Showing The Two Bearings Required To Transmit Constant In Service Loads Between A Railway Car 1 (37.3 KiB) Viewed 18 times

Consider Figure Q4 below, showing the two bearings required to transmit constant in- service loads between a railway car and one of its axles. Assuming that the two bearings must be identical, select an appropriate medium angular ball bearing (a=259) to provide one year of continuous operation at 300 rpm with 95% reliability. Assume that the thrust loads are shared equally between the two bearings, and there is a heavy impact. Please specify the bearing number of your selection. 800 lb 1800 lb 14" 20" 20" Figure Q4
