Paired Metric Taper Roller Bearing Sets: These bearings have both tapered inner and outer raceways, between which tapered rollers are situated. They are mounted in matched pairs either facing each other or back to back on a common dual outer raceway. The design of taper rollers makes them particularly suited to accommodating combined axial and radial loads typical of those experienced for example in wheel hubs or heavy rolling machinery.
Benefits: Used widely in transmissions, can be used in oil or greased, high radial and axial load
