SKF Tapered Roller Bearing 30216

SKF Tapered Roller Bearing 30216 The inner and outer ring Rare Segments of cones and the rollers are taperedso that the conical surfaces of the Raceways, and the roller axes if Projected, would all meet at a common point on the main axis of the bearing. This Geometry makes the motion of the cones remain coaxial, with no sliding motion between the Raceways and the outside Diameter of the rollers. This conical Geometry creates a linear contact patch which permits greater loads to be carried than with Spherical (ball) Bearings which have point contact. The Geometry means that the Tangential speeds of the surfaces of each of the rollers are the same as their Raceways along the whole length of the contact patch and no Differential Scrubbing occurs.The rollers are Stabilized and Restrained by a flange on the inner ring against which their large end slides, which stops the rollers from popping out due to the "pumpkin seed effect" of their conical shape. Tapered roller Bearings are Separable into a cone Assembly and a cup. The Non-separable cone Assembly Consists of the inner ring, the rollers, and a cage that retains and evenly spaces the rollers.
