Taper Roller bearings are generally separable, which means the cone assembly, consisting of the inner ring with roller and cage, can be mounted separately from the cup (outer ring). Being separable, mounting becomes easier. The projection lines of all the taper surfaces (Cup, Cone, and Roller) meet at a common point on the bearing axis, called the apex point, ensuring proper rolling motion of the roller on the track surfaces of cone and cup. NBC manufactures Single and Double Row Taper roller bearings in Inch and Metric series.

These bearings are mainly used in Wheels, Transmissions and Axle Centres of Passenger Cars, MUVs, Trucks, Tractors, Earthmovers, etc. where RPM is moderate and combination loads (i.e. simultaneously both axial and radial loads) are prevalent.
