Rotation accuracy and clearance details of CRBF8022AD face-mount crossed roller bearings
Accuracy P5 P4 P2 Radial run-out of the inner ring 5μm 4μm 2.5μm Axial run-out of the inner ring 5μm 4μm 2.5μm Radial run-out of the outer ring 13μm 8μm 5μm Axial run-out of the outer ring 13μm 8μm 5μm Clearance T1 C1 C2 Radial internal clearance -10~0μm 0~15μm 15~35μm CRBF8022AD crossed roller bearing features:
1. The inner/outer ring is a solid one-piece structure, so bearings can provide high stiffness.
2. One single bearing can sustain radial, axial, and moment loads at the same time.
3. High rigidity & rotation accuracy. The compact structure of the CRBF series reduces the influence of the installation.
4.Miniaturization. The inner ring and outer ring with mounting holes, so it can be easily mounted to a device with bolts without need for housing and fixing plate, so surrounding parts of the bearing can be made compact, which contributes to miniaturization and a weight saving of devices.CRBF8022AD crossed roller bearing installation instructions
CRBF8022ADUU Bearing Mounting Dimensions
da: 107mm
Da: 137mm
PCD1: 97mm
PCD2: 148mm
Inner ring mounting hole 10-φ5.5 drilled through, φ9.5 counterbore depth 5.4
Outer ring mounting hole 10-φ5.5 drilled through, φ9.5 counterbore depth 5.4
Cautions: For crossed roller bearings with split outer ring, when the rigidity of the mounting parts is not sufficient, stress concentration will occur at the contact area between the rollers and raceways, and the bearing performance will deteriorate significantly.
Therefore, it is necessary to carefully examine the rigidity of housing and the strength of fixing bolts when a large moment will be applied.
1. Before installation, please clean bearing bracket, shaft, or other components, make sure there is no burrs or rough edge.
2.Fix the inner and outer rings in the axial direction directly to the mounting surface by fixing bolts
3. If a large number of radial load and/or moment is applied, it is recommended to prepare the flange part as Fig.4.
