This bearing is used in rolling mill screw-on bearing arrangements. LYTBZ thrust tapered roller bearings have a logarithmic contact profile between raceways and rollers, ensuring optimal stress distribution in the bearing, thereby extending bearing life.

Since the rolling elements in the thrust tapered roller bearing are tapered rollers, structurally, since the rolling busbar and the raceway busbar of the washer meet at a certain point on the axis of the bearing, the rolling surface can form pure rolling and limit speed. higher than thrust cylindrical roller bearings.

Due to the small production volume of thrust tapered roller bearings, the models produced by various factories are mostly non-standard external dimensions, and the series of standard external dimensions are produced in fewer varieties, so there is no national standard for the external dimensions of such bearings.

Axial tapered roller SKF bearings of this type must be able to withstand extreme axial loads and allow angular displacement of the threaded shaft relative to the housing. Therefore, such bearings are usually full complement type, with large diameter and extra long rollers. To accommodate misalignment of the roll housing without adversely affecting bearing performance, this bearing has a spherical race. The race may be a shaft race or a bearing housing race.
