The AD series designates a multirow contact mill configuration, with the IR suffix indicating this is an inner race component sold separately from the outer race and roller assembly. Four-row cylindrical roller bearings in the AD series are engineered for roll neck applications in primary metals rolling mills, including rod, bar, and section mills, where extremely high radial loads are present and reliable, low-friction operation is required.
