If compared with other roller bearings, cross cylindrical roller bearings differ in the position and arrangement of miscellaneous fish rollers, which lie between the inner and outer wheels and are arranged at right angles to each other at intervals. Because of this special setting method, the roller in the bearing can bear the load from all directions at the same time.

In cross cylindrical roller bearings, the rollers are in linear contact with the track surface, so the bearing is loaded and the possibility of elastic deformation is very small. Such bearings are now widely used in industrial automated robots, working machinery and medical facilities, which require high rigidity, compactness and high speed to ensure accuracy.

For cross cylindrical roller bearings, because the cylindrical rollers are arranged vertically on the rolling surface of the V-groove at 90 degrees through the spacer retainer, one cross cylindrical roller bearing can bear all directions of load, such as radial load, axial load and moment load.

Although bearing products have been popularized, the quality of bearings and the maintenance of bearing products have also emerged. In order to make cross cylindrical roller bearings play a better role, it must be correctly and reasonably maintained.

For example, to give bearings a full rest, especially bearing wear after a long period of work; secondly, about the choice of lubricants and regular addition of supplementary lubricants, with the increase of the frequency of use, cross-cylindrical roller bearings surface grease will gradually wear out, regular addition of grease can keep them in good condition.

In addition, it is necessary to check the details of cross cylindrical roller bearings regularly, and eliminate all unfavorable factors in time to avoid further deterioration of the problem.
