33021
The 33021 is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 105mm 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 heavy industrial machinery where high load capacity and reliable performance under combined loading conditions are required. The set includes both cone and cup assemblies for complete installation.
