Tapered bearings have a cup and a cone knot. The cup consists of an outer ring, and the cone set consists of an inner ring, rollers and a seperator. The design of the tapered bearings is suitable for combined loads and provides low friction during operation. Single-row tapered bearings are the main and most widely used. Tapered bearings are used in motor shafts, axles, propellers and many other equipment and machines.
