Descriptions

Tapered Roller bearings are usually separated model, namely the belt roller and cage

components of inner ring of the cone inner ring and outer cone components can (outer)

separate installation.
Tapered roller bearing inner ring and a conical outer raceway, tapered roller are arranged

in between. All the cone surface projection line in the bearing of the same point together.

This design makes tapered roller bearing is especially suitable for bear composite (radial

and axial) load. Bearing axial load capacity is mostly composed of contact Angle α

decision; The greater the Angle α, axial load capacity is higher
Tapered roller bearing with logarithmic contact shape, in roller/raceway contact area to

provide the best stress distribution. Guide the flange and roller big-end sliding surface of

the special design, will significantly promote the roller end/flange contact surface oil

film formation. This leads to benefits including operation reliability enhancement, not

reduced susceptibility in.
