ItalianoHigh dimension spherical roller bearing
4020
High dimension spherical roller bearing is double row bearing with one spherical raceway on the outer ring and 2 raceways on the inner ring. The two raceways on the inner ring have a certain tilt with respect to the axle. For this reason this type of bearing neither does feel the effects of the shaft alignment errors with respect to the cage nor the effects of any possible sags in the shaft. It can support radial and axial loads with an axial load from both sides.
