Thin section Tapered roller bearings 32904 are separate bearings. inner diameter is 20mm, outer dimater is 37mm,width is 12mm.

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.

The basic dimensions of FQN tapered roller bearings are listed in the dimensional data sheet,
