Taper roller bearing has a tapered outer ring and a tapered inner ring assembly. The conical outer ring component consists of an outer ring, while the conical inner ring component consists of an inner ring, rollers, and a retaining structure. The structure of this bearing can adapt to combined loads and achieve low friction during operation. By adjusting a single row tapered roller bearing with another tapered roller bearing and applying a preload, a hard bearing application can be obtained.
