Cross Roller Bearing Skf-manufacture,factory,supplier from China

Structural features: The roller inside the cross roller bearing is combined in a cross arrangement, which makes the bearing able to withstand both radial and axial loads. There is a certain gap between the inner and outer rings, which can make the bearing maintain high rigidity when it is subjected to high torque load, and also has good rotation accuracy and stability. The design of the seal ring and cage of the cross roller bearing is also very important, which can effectively prevent dust and foreign matter from entering the bearing interior and extend its service life.

Cross roller bearing is a special kind of rolling bearing, which is widely used in mechanical field. It is designed to meet large size equipment that needs to operate under the requirements of high load capacity, high rigidity and high rotational accuracy. The cross roller bearing is composed of inner and outer rings, rollers, sealing rings and cages, and its structural advantages are that it can withstand both radial and axial loads, with high torque rigidity and running accuracy. The following will introduce the characteristics and applications of cross roller bearings in detail.

Applications: Cross roller bearings are widely used in many fields, including machine tools, engineering machinery, medical equipment, food packaging machinery, etc. On machine tools, cross roller bearings are often used to support the spindle and the turntable to ensure the high-speed and high-load operation of the equipment.

RU cross roller bearings are also known as bearings. The main body of a rolling body usually uses cylindrical or tapered rollers to intersect a single flow path, separated by retainers or spacers, and arranged in a cross pattern. Therefore, the cross roller ring group can withstand loads in all directions, with a stiffness of 3-4 times higher than traditional models. RU cross roller bearing is lubricated by spray. Drilled shrinkage air mixes spray and lubricating oil to produce oil mist.

Bearing performance: The bearing capacity of cross roller bearings is large, suitable for high-speed and high-load applications. Due to the special arrangement of rollers, the bearing can share part of the load when bearing radial and axial loads, which improves the bearing capacity and stability.

This type of bearing is widely used in industrial automatic robots, working machinery and medical facilities, where high rigidity, tightness and high speed are required to ensure accuracy.

Slewing bearing has four series of toothless, external and internal toothed four-point contact ball bearings, double row angular contact ball bearings cross cylindrical roller bearings, cross tapered roller bearings and three row cylindrical roller composite bearings, of which four-point contact ball bearings have higher static load capacity, cross cylindrical roller has higher dynamic load capacity, The pre-interference of cross-tapered roller bearing can make the bearing have greater support rigidity and rotation accuracy.

There are two main types of bearings widely used in industrial robots: constant cross-section thin-walled bearings and RU cross roller bearings. The bearing of an industrial robot is one of the key components suitable for the joints of industrial robots or the turntables of machining centers, robots, medical devices, measuring instruments, IC manufacturing equipment, etc., and has a wide range of uses.

The main features of rotary support bearings include high bearing capacity, fast speed, small friction, wear resistance, simple structure, easy installation and so on. It can withstand large axial and radial loads, while having high rigidity and accuracy, suitable for high-speed rotation and precision positioning requirements. Different types of rotary support bearings have differences in structural form and working principle, such as four-point contact ball type, two-way thrust ball type, cross roller type, tapered roller type and so on.

 Thrust needle and retainer assembly are comosed of a set of tray ring gaskets combined with retainer with roller bearings.The stand leads and holds many rolling elements.The thrust needle bearings or thrust-cylindrical roller bearings can support the bearings with the axial directional load and so the can be used as the bearings with good rigidity and minium axial occupied spaces.If the surface of the adjacent parts can be used as a tray for the rolling needles and the holding stand assembly should be recommended when the support space is big enough so that a small axial cross secti

Aligning roller bearings have two rows of rollers, mainly bearing radial loads, but also can withstand axial loads in either direction. It has high radial load capacity, especially suitable for heavy loads or dynamic loads, but cannot withstand pure axial loads. This kind of bearing outer ring raceway is spherical shape, so its aligning performance is good, can compensate for the coaxial error.Self-aligning roller bearings are divided into two different structures according to the roller cross section shape: symmetrical spherical roller bearings and asymmetric spherical roller bearings.

Product Description:In interior decoration, it can be used to make decorative strips, partitions, screens and so on. Its diverse cross-section shapes and processing methods can create a rich decorative effect.

The raceway with the inclination Angle enables the tapered roller bearing to bear the combined radial and axial loads. The greater the Angle between the outer raceway and the bearing center line, the greater the ability to withstand the axial and radial load ratio. The linear contact between the roller and the raceway makes the tapered roller bearing have a great load bearing capacity. This feature and the ability to withstand radial loads, axial loads and both combined loads make tapered roller bearings ideal for many applications.

When the rotary support bearing is working, the inner and outer rings realize relative rotation through the combination of rolling elements. When the external force acts on the bearing, the load is transmitted to the inner and outer rings, and is transmitted to each other through the rolling element, achieving the carrying capacity. At the same time, the rolling motion of the rolling element reduces the friction force and improves the rotation efficiency of the bearing.

Single Row Angular Contact BearingsThese single row angular contact bearings are suitable for general use where axial loads are applied in only one direction. They are stand-alone bearings and are not designed to be combined or mated with another bearing.Double Angular Contact BearingsDuplex bearings are two matched bearings that provide precise alignment both radially and axially. By using duplex bearings, vibrations can be eliminated and higher load capacities can be achieved.

Deep groove ball bearing is the most representative rolling bearing, widely used. Suitable for high and even extremely high speed operation, and very durable, no frequent maintenance.
