cross roller bearing

Crossed roller bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads.The crossed roller bearing has high precision, and because the spacer is installed between the vertically arranged rollers, it prevents the rollers from falling over or the rollers rubbing against each other, so it can prevent the increase of the rotational torque. In addition, compared with conventional types using iron plate cages, one side of the rollers does not come into contact or lock up. Stable rotational motion can be obtained even when a preload is applied. And since the inner ring or the outer ring is divided into two parts, the preload can be adjusted, so the rotational motion can be obtained. RE standard type is an innovative bearing based on the design of the RB standard type bearing. The inner ring is separable while the outer ring is integrated into the main body. It is used in cases where the high rotational accuracy of the outer ring is required.

With the development of intelligence and mechanization in the smelting industry, it provides irreplaceable huge business opportunities for the application of slewing bearings. Because it can be used in robotic arms, fully automatic intelligent robots, ladle rotary tables and other industries. Therefore, flexible mechanical equipment will become the general trend of many factories. The rotary table is composed of arm system software, fixed tower, rotating drive and other components. It is typically a light-loaded low-speed turning machine. The slewing bearing of the rotary metallurgical furnace generally uses a three-row roller structure slewing bearing. This structural product is a slewing bearing with high bearing capacity, which is mainly used in the operation with a large load. It is composed of three ferrules, the upper and lower rows of rollers are horizontally distributed, and the radial force is borne by the three rows of rollers arranged vertically, so it can bear the axial force and tilting moment from two directions. This kind of large three rower slewing bearing is our featured product with advantages of high load, high precision and long service life.

Crossed roller bearings are lightweight, compact bearings with thinnest possible inner and outer rings with high rigidity, because of its vertical arrangement of cylindrical rollers with a 90°V groove through the separate spacers in the deep groove rolling surface. This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads. RA thin type is a small and light weight bearing with a very thin wall thickness. The miniaturized design of thin-walled size is helpful for the light and thin design of related structures. The overall structure of the inner ring is more suitable for occasions with high rotation accuracy of the inner ring, and the stable rotation accuracy reaches microns; it is suitable for precision testing instruments, robot joints, and direct drive torque. Motors, high-precision turntables and other applications requiring high precision and high rigidity.

This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads. SX series (integral inner ring, split outer ring, ultra-thin), under the same shaft diameter, this type has a smaller sectional dimension than the RB series. Due to the ultra-thin design, the outer ring and inner ring have no mounting holes , It needs the flange and the support seat during installation, which is suitable for applications where the inner ring rotates.

This special design allows just one bearing to carry loads in all directions including radial, axial and moment loads. RU special type is a bearing with integrated inner- and outer ring. Since the inner and outer rings have been machined with mounting holes, there is no need to fix the flange and the support seat, which shortens the axial space distance and optimizes the use mechanism. In addition, due to the integrated inner and outer ring structure with seat, installation has little effect on performance, so stable transmission accuracy and torque can be obtained. Both inner and outer ring rotating mechanisms are suitable. Widely used in robot waist joints, welding multi-station rotary table, communication radar, precision measuring instruments, etc.

The inner and outer rings are ultra-thin. Due to the ultra-thin design and the outer ring and inner ring without mounting holes, the mounting requires the flange and the support to be fixed. In addition, since the outer ring and the inner ring are both integral structures, the mounting has no effect on the performance, so that stable rotation accuracy and torque can be obtained, which is suitable for the outer ring and the inner ring to rotate, but there are occasions where the size is small.

RB standard type is a bearing with thinnest possible inner and outer rings because the outer ring is split while the inner ring is integrated into the main body.
