Tapered roller thrust bearings
Tapered roller thrust bearings enable axially very compact bearing arrangements to be produced which can carry very heavy axial loads, are insensitive to shock loads and are stiff. SKF produces single direction tapered roller thrust bearings (fig 1) and double direction tapered roller thrust bearings (fig 2). The screw-down bearings (fig 3) constitute a special design of single direction tapered roller thrust bearing and have a full complement of rollers. They are used for rolling mill screw-down arrangements.
SKF tapered roller thrust bearings are produced with the logarithmic contact profile between raceways and rollers to guarantee optimum stress distribution in the bearing, thus enhancing bearing life.
SKF tapered roller thrust bearings with cage are of separable design so that the two washers and the roller and cage thrust assembly can be mounted separately and easily. The full complement screw-down bearings are held together by special retaining components and, to simplify handling, the washers have threaded holes for eye bolts.
