The 33030 is a metric tapered roller bearing conforming to ISO 355 standards, designed with a 150mm bore diameter, 225mm outside diameter, and 59mm width. Tapered roller bearings use conical rollers guided by a cage between inner and outer ring raceways, capable of supporting combined radial and axial loads.
This bearing type is commonly used in heavy industrial applications including gearboxes, rolling mills, mining equipment, and construction machinery where robust load capacity and durability under combined loading conditions are required. The tapered geometry allows for precise adjustment of bearing clearance during installation.
