End play is the total distance the shaft can move between the two thrust bearings and is sometimes called float, thrust bearing clearance or axial clearance. Example: a 10.5" thrust bearing would require .015" of end play. The normal tolerance is 0.005", so the EP range would be 0.013" – 0.018". While these values are typical, larger or ...
