The structure and assembling accuracy of imperial taper roller bearing

The structure and assembling accuracy of imperial taper roller bearing are different from that of metric bearings. Used for import machinery or special needs of the industry.  
Imperial taper roller bearing are tapered roller bearings whose dimensions are measured in inches, originating from British and American countries.   
Structure of imperial taper roller bearing: single column double column four column  

A single imperial taper roller bearing has an outer ring, and its inner ring and a set of tapered rollers are enclosed by a basket cage into an inner ring assembly. The outer ring can be separated from the inner ring components. In accordance with the ISO dimensions standard for tapered roller bearings, any standard type of imperial taper roller bearing outer ring or inner ring components should be able to achieve international exchange with the same type of outer ring or inner ring components. 

That is, the outer ring of the same type in addition to the external size, tolerance should comply with ISO492(GB307) provisions, the cone Angle of the inner ring component, component cone diameter must also comply with the relevant provisions of the exchange.  
Generally, the conical Angle of the outer raceway of single row tapered roller bearings is 10°~19°, which can bear the joint action of bearing load and radial load at the same time.  The larger the cone Angle, the larger the axial load capacity.  Bearing with large taper Angle, post code plus B, cone Angle between 25°~29°, it can withstand large axial load.  In addition, single row tapered roller bearings can adjust the size of the clearance during installation.
