SKF 11590/11520 Tapered roller bearing

SKF 11590/11520 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 = 100 mm per ISO 15.
