WebApr 1, 2002 · Internal clearance can be separated into two categories: radial and axial. The total internal clearance is the amount that one ring can be displaced relative to the other ring, either radially or axially. The radial clearance is the total clearance between the raceway and the rolling elements measured normal to the bearing axis.
