31300 Series

31330XJ2

A tapered roller bearing is a type of bearing designed to handle both radial and axial loads. It consists of an inner ring, an outer ring, and tapered rollers arranged between them. The rollers are shaped like cones, which allows the bearing to support high loads while reducing friction. Tapered roller bearings are commonly used in applications such as automotive wheels, gearboxes, and industrial machinery, where both radial and axial forces are present. These bearings offer durability, high load capacity, and efficiency in a wide range of settings.
