Thin section Tapered roller bearings 30204 are separate bearings. inner diameter is 20mm, outer dimater is 47mm,width is 15.3mm.



The single-row tapered roller bearing's ability to withstand axial load depends on the contact angle, that is, the outer ring raceway angle. The larger the angle, the greater the axial load capacity. The most used tapered roller bearings are single-row tapered roller bearings. In the front wheel hub of the car, a small double-row tapered roller bearing is used. Four-row tapered roller bearings are used in heavy machines such as large cold and hot rolling mills.
