A. Tapered Roller Bearings, according to the number of rollers, are defined as single row, double rows and four rows. The single row tapered roller bearings clearance should be adjusted when they are mounted. For double rows and four rows tapered roller bearings, the clearance can be provided when assembling them according to national standards. 

B. The tapered roller bearings mainly carry radial, axial combined load with radial load in the main. The capacity of axial load carrying depends on the contact angle of outer ring's raceway. The bigger the contact angle is, the greater the capacity will be. 

C. The bearings are mainly used in metallurgy, milling, rolling mills, automobiles, machines, plastics and other industries.
