JL819349/JL819310 Tapered Roller Set-Inch Series and J Series

The JL819349/JL819310 is a single row tapered roller bearing set consisting of a cone (inner ring) and cup (outer ring) assembly. This inch-series bearing uses tapered rolling elements arranged between tapered raceways to accommodate combined radial and thrust loads.

Tapered roller bearings are commonly used in automotive wheel hubs, differential assemblies, gearboxes, and industrial machinery where both radial and axial loads must be supported. The separable design allows for adjustment of bearing clearance during installation and maintenance.
