30218J Tapered Roller Metric Type

The 30218J is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 90 mm bore diameter. Tapered roller bearings use conical rollers arranged between inner and outer ring raceways 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 load capacity and precise shaft guidance. The tapered geometry allows for adjustable preload and optimal load distribution under demanding operating conditions.
