HM911244/HM911210 Tapered Roller Set-Inch Series and J Series

The HM911244/HM911210 is a tapered roller bearing set consisting of a cone (inner ring with rollers and cage) and cup (outer ring). This inch-series single row design provides high radial and thrust load capacity through its tapered raceway geometry, with rollers positioned to ensure all load lines converge at a common apex point on the bearing axis.

Tapered roller bearing sets are widely used in heavy-duty industrial applications including agricultural equipment, construction machinery, commercial vehicles, and material handling equipment. The extensive cross-reference list indicates use across multiple OEM applications in trucks, forklifts, and industrial equipment from manufacturers including GM, Mack, Hyster, Clark, and Kenworth.
