Cross tapered roller bearings are composed of two columns of mutually perpendicular bearing raceways and a set of tapered rollers arranged in a 90 ° cross arrangement. The rollers are separated by nylon isolation blocks, which reduces the inclination and friction between the rollers, reduces the rotational torque, and can withstand combined loads such as radial loads, axial loads, and overturning moments.

This bearing has high rotational accuracy, with commonly used accuracies being P5 and P4 levels. The cross tapered roller bearing adopts a large cone angle and cone geometry design, which makes the overall span of the bearing larger; Its rotational speed is much higher than that of crossed cylindrical roller bearings, and its friction torque is also lower than that of crossed cylindrical roller bearings.
