3784/3720
The 3784/3720 is a tapered roller bearing set consisting of a cone (inner ring with rollers and cage) and cup (outer ring). Tapered roller bearings use conical raceways and tapered rollers to handle combined radial and thrust loads, with load capacity increasing with the contact angle.
This bearing type is widely used in automotive wheel hubs, truck axles, gearboxes, and heavy industrial equipment where both radial and axial loads must be supported. The set configuration ensures proper matching of cone and cup components for optimal performance.
