Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered rollers are arranged. Their design makes tapered roller bearings particularly suitable for carrying combined (radial and axial) load.
According to dimensional standard difference, tapered roller bearings can be grouped into metric and inch size series.
