30221J Tapered Roller Metric Type

The 30221J is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 105 mm bore diameter and belonging to the 302 series. Tapered roller bearings use conical rolling elements to handle combined radial and axial loads simultaneously, with load capacity increasing proportionally to the contact angle.

This bearing type is commonly used in automotive wheel hubs, gearboxes, differential assemblies, and industrial machinery requiring precise positioning under heavy loads. The separable design allows for independent mounting of the inner and outer ring assemblies, simplifying installation and maintenance procedures.
