The structure, assembly dimension accuracy and rotation accuracy of inch tapered roller bearings are different from those of metric bearings.It is mostly used in imported machinery or industries with special needs.British tapered roller bearing refers to the tapered roller bearing whose overall dimensions are measured in inches, which originated from Britain and the United States;Structure: single row double row four row single tapered roller bearing has an outer ring, and its inner ring and a group of tapered rollers are wrapped into an inner ring assembly by a basket cage.The outer ring (or inner ring) of double row tapered roller bearing is a whole.The small end faces of the two inner rings (or outer rings) are similar, and there is a spacer ring in the middle. The clearance is adjusted by the thickness of the spacer ring. The thickness of the spacer ring can also be used to adjust the pre interference of double row tapered roller bearings.The four row tapered roller bearing has four rows of rollers, which can withstand extreme radial load and bidirectional axial load, and the limiting speed is low.It is widely used in various cold and hot rolling mills.
