Crossed roller bearing structural features:
with crossoverRoller bearings, cylindrical rollers are arranged in a cross arrangement, each roller is perpendicular to the adjacent roller, located in a 90° V-shaped groove, and are separated from each other by an isolation cage. This design allows only one bearing to carry loads in all directions, including radial, axial and moment loads. Because crossed roller bearings have high rigidity and an accuracy of up to P4.P2, although the sizes of the inner and outer rings are as small as possible, they are most suitable for applications such as joints and rotating units of industrial robots, rotating tables of machining centers, etc. Robot rotating devices, precision rotating tables, medical equipment, measuring instruments, IC manufacturing machines
Rotation accuracy:
Spacers installed between cross-arranged rollers prevent roller skew and an increase in rotational torque due to friction between rollers. Unlike conventional types that use steel plate cages, crossed roller bearings do not cause shifting or locking of the rollers and provide stable rotational torque. Since the inner and outer rings are designed to be separable, the bearing clearance can be adjusted. In addition, preload is provided by adjusting the bearing clearance to ensure high-precision rotational movement.
Features of use
The inner and outer rings are separable and are fixed to the crossed roller bearing body after the rollers and spacers are installed. This process prevents the rings from separating from each other. Therefore, it is easy to handle the rings when installing this type.
