SKF 322/28B Tapered roller bearing

SKF 322/28B tapered roller bearing. Single-row tapered roller bearing designed to take combined heavy radial and one-direction axial load. Rollers, inner ring raceway (cone) and outer ring raceway (cup) are ground to converge at a common apex on the bearing axis. Two bearings are always mounted in opposition so the pair carries axial load in both directions and can be preloaded to remove all internal clearance. Metric dimensions per ISO 355 / ISO 492 Class Normal. Bore diameter d = 140 mm per ISO 15.
