32311
The 32311 is a metric tapered roller bearing conforming to ISO 355 standards, featuring a 55mm bore diameter, 120mm outside diameter, and 45mm width. Tapered roller bearings use conical raceways and tapered rollers 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 positioning. The tapered geometry allows for adjustment of bearing clearance during installation to optimize performance and preload.
