The 30211J is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 55 mm bore diameter and belonging to the 302 series. Tapered roller bearings use conical rolling elements to handle combined radial and axial loads efficiently.
This bearing type is commonly used in automotive wheel hubs, gearboxes, differentials, and industrial equipment where both radial and thrust loads are present. The tapered design allows for precise adjustment of bearing clearance and optimal load distribution.
