Cross tapered roller bearings are composed of two rows of bearing tracks that are perpendicular to each other and a group of tapered rollers that are arranged at 90 ° to each other. The rollers are separated by nylon spacers to prevent the tilting and friction of the rollers. And reduces the rotating torque, thus it can bear combined loads such as radial load, axial load and multi-direction loads.
The bearing has high rotation accuracy, and the commonly used accuracy is P5 and P4. Cross tapered roller bearings use a large tapered angle and tapered geometric design to make the bearing have a larger span; its limiting speed is much higher than the cross cylindrical roller bearing, and the friction torque is lower than the cross cylindrical roller bearing.
