30200 series bearings are one series of tapered roller bearings.The bearing is a radial thrust type rolling bearing in which the rolling elements are tapered rollers. Tapered bearings can be divided into single row tapered roller bearings, double row tapered roller bearings, and four row tapered roller bearings.Tapered roller bearings are usually of a separate type, ie a conical inner ring assembly consisting of an inner ring with a roller and cage assembly can be mounted separately from the outer bevel (outer ring).
