Tapered roller bearings 32203 are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction. When the bearing is subjected to a radial load, an axial component will be generated, so when another bearing that can bear the axial force in the opposite direction is needed to be balanced.
