Taper roller bearings are widely used in automobiles, rolling mill, mining, metallurgical, plastic machinery, etc.


A conical taper roller bearing outer ring groove and inner circle, tapered roller are arranged in between. All the conical surface in bearing axis projection line the same point again. This design makes tapered roller bearing composite (particularly suited to bear radial and axial) load. Bearing axial load ability most is decided by the contact Angle is alpha; Alpha greater perspective, axial load capacity is higher. Angle size by calculating coefficient e to say; E value, the greater the contact Angle, the bigger the axial load bearing the greater the applicability.


Taper roller bearings are usually separated type, namely the belt roller and maintains a component within the cone of circles within circles conical outer components can and (outer ring) apart installation .
