Inch Taper Roller Bearing Description
Tapered Roller Bearings generally come in two parts - the cone (consisting of the inner ring and roller cage assembly) and the cup (outer ring). The Part Number for these bearings is comprised of the "Cone Reference / Cup Reference". These two parts can be mounted separately.
Tapered Roller Bearings are particularly suited to the accommodation of combined radial and axial loads
