32309J Tapered Roller Bearing | Metric Single Row

32309J The 32309J is a metric tapered roller bearing from the 323 series with a 45 mm bore diameter, conforming to ISO 355 standards. Tapered roller bearings use conical rolling elements to support combined radial and axial loads, with load capacity proportional to contact angle. These bearings are commonly used in industrial gearboxes, automotive wheel hubs, railway axle boxes, and heavy machinery where both radial and thrust loads are present. The tapered geometry allows for adjustment of bearing clearance during installation and accommodation of thermal expansion. 32309JOutside Diameter Inch: 3.937 Outside Diameter mm: 100 For large orders ($2000+) please inquire by email.
