Features of cross cylindrical roller bearings

Structural features

The cross cylindrical roller bearing is a bearing with cylindrical rollers cross-arranged vertically between the inner and outer rings, there is a line contact between the roller and the raceway, with a high rigidity and very small elastic deformation under any load, and it can bear radial load, axial load and moment load at the same time, so it is especially suitable for applications with the requirements of high rigidity and rotation accuracy.

The sizes of inner and outer rings are minimized; especially for ultra-thin type, its sizes are close to the limit sizes, and it has a high rigidity, to simplify the bearing structure in the design, so it is especially suitable for applications for joints or rotating portions of industrial robots, the rotary benches of machining centers, manipulator rotation portions, accuracy rotary tables, medical equipment, measuring equipment, IC manufacturing equipment and etc.
