The 34300/34478 is a tapered roller bearing set consisting of a cone (inner ring with rollers and cage) and cup (outer ring). This inch-series design provides high radial and thrust load capacity through its tapered raceway geometry, with loads transmitted along converging lines to a common apex point.
Tapered roller bearing sets are widely used in automotive wheel hubs, truck axles, gearboxes, and industrial machinery where combined radial and axial loads must be supported. The separable design allows for precision adjustment of bearing clearance during installation and maintenance.
