Tapered roller bearing
RKB Europe
The rollers are guided tangentially by the cage and axially by the big rib of the inner ring, on which they have contact. As between rollers and raceways there is linear contact, they can take heavy radial loads. They can also take heavy axial or combined loads, depending on the contact angle caused by the tapered elements.
The contact angle is the one of the outer raceway generatrix.
The single row taper roller bearings are of separable design, which means the outer ring/cup and the inner ring/cone with rollers and cage assembly can be separately mounted. The two parts are interchangeable.
RKB taper roller bearings are manufactured both in standardized (metric and inch sizes) and in non-standardized constructive version.
The metric single bearings have standardized dimensions as listed in ISO 355:1977 and those designated with prefix J conform to American AFBMA 19.1/1987. The inch size bearings conform to American AFBMA 19/1974
