30208J Tapered Roller Metric Type

The 30208J is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 40 mm bore diameter and belonging to the 302 series. Tapered roller bearings use conical raceways and tapered rollers to handle combined radial and axial loads efficiently.

This bearing type is commonly used in automotive wheel hubs, gearboxes, differential assemblies, and industrial machinery requiring high radial and thrust load capacity. The tapered geometry allows for adjustable preload and accommodates misalignment in heavy-duty applications.
