China Standard XSU Series Crossed Roller Bearings wholesaler

XSU Series Crossed Roller Bearings

XSU series crossed roller bearings (integral type of outer ring and inner ring), because the outer ring and the inner ring have mounting holes, there is no need to fix the flange and support seat during installation. In addition, because the outer ring and the inner ring are integral structures, the installation has almost no impact on performance, so it can obtain stable rotation accuracy and torque and can be used in situations where the outer ring and inner ring rotate. This type of bearing is widely used in industrial robots, work machinery, medical facilities, etc., where high rigidity, tightness, and high speed can still ensure accuracy.

XSU Series Crossed Roller Bearing Features:

1. Excellent rotation accuracy. The XSU series crossed roller bearings produced by HZPT Machinery Equipment Co., Ltd can provide negative clearance types, and accuracy grades P5 / P4 / P2.

2. Simplified installation. XSU series cross roller bearings have mounting holes on the inner and outer rings. No flange or support is required for installation. In addition, because the outer ring and the inner ring are integral structures, the installation has almost no impact on performance, so it can obtain stable rotation accuracy and torque and can be used in situations where the outer ring and inner ring rotate.

3. Withstand large axial and radial loads. Because the rollers are arranged perpendicular to each other on the raceway through the spacer, they are in line contact with the raceway, not point contact with the ball turntable bearing.

4, greatly save installation space.

5. Reduce the shaft length and processing cost. The thermal expansion causes limited changes in geometric dimensions.

6. Using nylon divider, low moment of inertia, low starting torque, easy to control angular division.

7. Optimized pre-tightening force, high rigidity, and high precision of guide roller operation.

Installation Procedure:

1. Thoroughly clean the housing and other parts to be installed, and check to determine if deburring is required.

2. Since the Cross-Roller Ring is a thin-wall bearing type and therefore tends to misalign when installed, for ease of this situation, gradually drive the product into the housing or onto the shaft by gently hitting it with a plastic hammer while keeping the product horizontal. Taking care, continue to hammer until it fully contacts the reference surface.

3. Place the presser flange onto the Cross-Roller Ring. Rock the flange several times to match the bolt holes.

4. Insert the presser bolts into the holes. Manually turn the bolts and ensure they do not display skewing caused by the misalignment of the holes.

5. Tighten the presser bolts in 3 to 4 steps from light to complete tightening by repeatedly securing the bolts in a diagonal order. When drawing (the separable inner or outer ring, slightly turning the integral outer or inner circle will correct the dislocation between the ring and the body.

Applications

Robots, machine tools, handling systems, precision rotary tables, hollow rotating platforms, radar, precision measuring instruments, etc.
