ZENGKUN cross roller bearing

Crossed roller bearings Crossed roller bearings Cylindrical rollers of crossed roller bearings are arranged at 90 ° intervals on the raceway. The rollers are equipped with spacers or spacers to prevent friction between the rollers caused by the inclination of the rollers. Lock-up occurs; Crossed roller bearings can withstand loads from all directions (such as axial, radial, or overturning loads) at the same time. The roller is in line contact with the raceway surface, so the bearing is less likely to deform elastically under load. Structure of Zengkun crossed cylindrical bearings The structure of the crossed cylindrical roller bearing is divided into three types of outer ring split type, inner ring split type and inner and outer ring integrated type. The rolling elements are short cylindrical rollers arranged at 90 ° to each other in a V-shaped raceway. The rollers are separated by a spacer. This structural design allows a single bearing to withstand axial loads, radial loads, and overturning moments. At the same time, bearings have high rigidity, high rotation accuracy and high bearing capacity, so they are suitable for rotary joints of industrial robots, rotary tables of machining centers, precision rotary tables, medical machines, measuring instruments, etc. Because the rollers are arranged in a cross, only one set of crossed roller collars can bear the load in all directions. Compared with the traditional model, the rigidity is increased by 3 to 4 times. Due to its special structure, it is usually used as an articulated bearing in industrial robots. RU series crossed roller bearings RU Crossed Roller Bearing RU type (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 and medical facilities, etc., where high rigidity, tightness and high speed can still ensure accuracy. RU Crossed Roller Bearing Features: 1. Excellent rotation accuracy. The RU series crossed roller bearings are made by Henan Zengkun Machinery Equipment Co.,Ltd can provide negative clearance types, accuracy grades P5 / P4 / P2. 2. Simplified installation. RU 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, high precision of guide roller operation.
