30209JR Tapered Roller Bearing, 45 mm Inner Diameter x 85 mm Outer Diameter x 20.75 mm Width

30209JR The 30209JR is a metric tapered roller bearing conforming to ISO 355 standards, with a 45 mm bore diameter from the 302 series. Tapered roller bearings use conical rolling elements between inner and outer race cups to handle combined radial and axial loads. This bearing type is commonly used in automotive wheel hubs, gearboxes, differential assemblies, and industrial conveyor systems where both radial and thrust loads must be supported. Tapered roller bearings are typically mounted in opposing pairs to handle bidirectional axial forces. For large orders ($2000+) please inquire by email.
