What is the basic introduction of thin-walled crossed cylindrical roller bearings?

Thin-walled crossed cylindrical roller bearings are composed of two major categories, one is the crossed cylindrical roller bearing, and the other is the crossed tapered roller bearing. When used, they are widely used due to their own particularity and incomparable superiority over other bearings. Let me tell you about its related knowledge points.

　　Thin-walled crossed cylindrical roller bearings have rotational accuracy. The internal structure of the crossed roller bearing uses rollers arranged at 90° perpendicular to each other. Spacers or gaskets are installed between the rollers to prevent the rollers from tilting and rolling. The grinding wheels grind against each other to effectively prevent the increase of the rotational torque. In addition, when using it, there will certainly be no contact or jamming of the rollers; at the same time, since the inner and outer rings are split structures, the gap can be adjusted, and high-precision rotational motion can be obtained even if a preload is applied. The operation and installation are simplified. The outer ring or inner ring is divided into two parts. The rollers and the cage are fixed together after installation, and the operation during installation is very simple. The method of using thin-walled crossed cylindrical roller bearings is that since the rollers are arranged perpendicular to each other through partitions on the 90° V-groove rolling surface, they can withstand large axial and radial loads. Of course, this design enables thin-walled crossed cylindrical roller bearings to withstand large radial loads, axial loads, moment loads and other loads in all directions.

　　The emergence of thin-walled crossed cylindrical roller bearings can greatly save installation space. The design of thin-walled crossed cylindrical roller bearings can provide higher rotation accuracy and rigidity in a smaller space, significantly saving material costs. This type of bearing is a right-angled installation of two sets of bearing raceways and rollers, with adjacent rollers in opposite directions, spacers between the rollers, and support washers on the rollers. This allows the two half-columns of the roller to fit into the same space. And the angle and tapered geometry of the bearing make the effective span of the bearing several times larger than the actual width of the bearing itself. Therefore, thin-walled crossed cylindrical roller bearings are suitable for high-speed machine tool applications such as vertical boring machines and vertical grinders. They are also particularly suitable for many equipment with limited space and high requirements for rotational accuracy.
