30318

The 30318 is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 90mm 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, conveyor systems, and industrial machinery where simultaneous radial and thrust loads are present. The tapered design allows for precise adjustment of bearing clearance during installation.
