30306J Tapered Roller Metric Type

30306J The 30306J is a tapered roller bearing with a 30 mm bore diameter, conforming to ISO 355 metric standards. Tapered roller bearings use conical raceways and tapered rollers to support combined radial and axial loads, with load capacity increasing proportionally to bearing size. This bearing type is commonly used in automotive wheel hubs, gearboxes, differential assemblies, and industrial machinery where both radial and thrust loads must be accommodated. Tapered roller bearings are typically mounted in pairs or in opposition for optimal load distribution.
