Taper roller bearings comprise solid cone and cup with tapered raceways and tapered rollers with cages. The bearings are not self-retaining. As a result, the inner ring together with the rollers and cage can be fitted separately from the outer ring. it can support axial loads from one direction as well as high radial loads. They must normally be axially adjusted against a second bearing fitted in a mirror image arrangement.

It is mounted by the circle pedestal rollers. And the roller is ridded by the cone rib. This type of bearing can support the combined (radial and axial) load, expecially the radial direction. It gathers all the tapered surface (cone surface, cup surface, roller raceway surface) top points with one point on the centre line of bearing. The load capability is decided by the cup raceway-angle. we can classify the taper roller bearing as per the rows.(single row, double row, four row) .clearance of single row tapered roller bearing need be adjusted when it is mounting. the clearance of double and four row tapered roller bearing clearance had been given as per the clients’ requirement before they leave the rolling mill or other factory.
