30303-zz 30303-2rs single row tapered roller bearings
Tapered roller bearings are separable bearings, bearing within the outer ring raceway has a cone line. This kind of bearing the number of columns loaded roller different structure type is divided into single row, change row and four-row tapered roller bearings. Single row tapered roller bearings can bear radial load and single direction axial load. When the bearing radial load to bear, it will produce an axial component to be balanced so when need another bearing axial force can withstand the opposite direction.
Single row tapered roller bearing axial load capacity depends on the contact angle, the outer ring raceway angle, the greater the angle, the greater the axial load capacity. Tapered roller bearings in the largest amount of single row tapered roller bearings. Sedan front wheel hub, with the use of the small size of the double-row tapered roller bearings. Four-row tapered roller bearings used in large-scale cold and hot rolling mill heavy machinery.
