what’s tapered roller (02,03,13,20,22,23,29,30,31,32) series bearings? where’s single’ double’ multi row tapered roller(inch or metric) bearings manufacturer? how to buy tapered roller thrust^radial bearings?

the inner and outer ring raceways and rollers of this type of bearing are made with a taper so that the planes of the surfaces of the raceways and roller axis meet at a point. The rollers are guided by the cone back-face rib.

A single row tapered roller bearing can support a combined radial and axial load. the size of the angle is indicated by the calculation factor:, the larger the contact angle. A single row tapered roller bearing is typically adjusted against a second tapered roller bearing.

tapered roller bearings utilize conical rollers and raceways, arranged so that the rollers and raceways meet at a common apex. The rollers are guided by contact between the large end of the roller and a rib on the inner ring. This provides high capacity for radial and single thrust loads.
