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 = 25°) 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 c.g. 1800 lb 14" 6" 3" 20" 20" Figure Q4
