Tapered roller bearing belongs to separable bearing. Both its inner ring and outer ring have taper rolling way. Tapered roller bearing can be divided into single row, double row and four-row bearing according to the column number of roller. Single row bearing can bear radial bearing and the single-direction axial load.The capacity of bearing axial load depends on the contact angular. That is to say, the bigger the contact angular is, the larger the capacity is. The widely used bearing is single row tapered roller bearing. Small size double row tapered roller bearing is often used in car’s front wheel hub. Four-row tapered roller bearing is used in large cold, hot rolling mill and other heavy machinery.
