30320 Tapered roller bearing (metric, ISO 355) 100x215x51mm

The 30320 is a metric tapered roller bearing conforming to ISO 355 standards, with a 100mm bore diameter, 215mm outside diameter, and 51mm width. Tapered roller bearings use conical rollers arranged between inner and outer ring raceways to handle combined radial and axial loads simultaneously.

This bearing type is commonly used in heavy-duty industrial applications including gearboxes, rolling mills, mining equipment, construction machinery, and wheel hubs where both radial and thrust loads must be supported. The tapered geometry allows for accurate adjustment of bearing clearance and optimal load distribution.
