The structure of forked cylindrical roller bearing is divided into outer ring and inner ring as a whole. The outer ring as a whole, the inner ring split and the outer ring as a whole are three forms. The rolling body is cylindrical rollers, which are vertically arranged in a V-shaped raceway at 90° to each other. The rollers are separated by an isolation block. This structure enables a single bearing to bear axial load, radial load, overturning moment and other loads. At the same time, the shape size is the largest miniaturization, and the bearing has high rigidity and rotation accuracy and composite bearing capacity, suitable for industrial robot joint and rotation part, machining center rotary table, manipulator rotary table, precision rotary table, medical machinery, measuring instrument and other applications. The main types of Luoyang Baina cross cylindrical roller bearings are:
Type RB (integral inner ring, separate outer ring), this model is the basic type of cross roller bearing. The outer ring is divided into two pieces, and the inner ring is an integral structure, which is most suitable for occasions requiring inner ring rotation accuracy.
RE type (split inner ring, integral outer ring), also the basic type of cross roller bearing, the size and RB type are the same, but the structure of the integral outer ring, inner ring is divided into two pieces, the most suitable for the occasions requiring inner ring rotation accuracy.
RU type (inner and outer ring as a whole, with mounting holes), because the outer ring and inner ring have mounting holes, installation does not need to fix the flange and support seat. In addition, since both the outer and inner rings are integral, the installation has little impact on performance, thus achieving stable rotation accuracy and torque. Suitable for outer and inner ring rotation.
RA type (integral inner ring, separate outer ring, ultra-thin), this model is the RB type inner ring thickness reduced to the limit of the compact, structure and RB type outer ring split structure, the most suitable for light weight, joint design, such as robot and manipulator rotating parts.
Ra-c type (inner and outer ring whole, outer ring crack), the main size and RA type is the same, because the model for the outer ring has a notch structure, the outer ring also has high rigidity, so it is also used in the application of outer ring rotation.
SX type (integral inner ring, separate outer ring, ultra-thin), under the same axial diameter, this type has a smaller section size than RB type, due to the use of ultra-thin design, outer ring and inner ring without mounting holes, installation needs flange and support seat fixed, suitable for the application of inner ring rotation.
CRBH (integral inner and outer ring, ultra-thin), due to the ultra-thin design and no mounting holes for outer and inner rings, flange and support seat are required to be fixed during installation. In addition, because the outer ring and inner ring are integral structure, installation has no impact on performance, can obtain stable rotation accuracy and torque, suitable for the outer ring and inner ring rotation but there is a small size requirements of the occasion
