WebInternal clearance is the distance which the two rings of a non-installed bearing can move when they are pushed in opposite directions. A distinction is made between radial and axial clearance. Radial clearance is measured perpendicular to a bearing’s central axis, while axial clear-ance is measured along the central axis. http://www.gearseds.com/files/6.3.1_Gear_Terms_Lesson_rev3.pdf

WebEnd 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 ... WebFor external gears it is measured in the root and for internal gears it is measured at the minor tip of the tooth.
