Rotary support bearings are widely used in various mechanical equipment and construction machinery, such as cranes, rotary tables, machine tools, wind power equipment, drilling RIGS, excavators and so on. In these equipment, the rotary support bearing assumes the important role of supporting the rotating member, ensuring the normal operation of the equipment. At the same time, it is also widely used in high-end fields such as aerospace, ocean engineering, and automated production lines.

Rotary bearing is an important mechanical component, which is widely used in various industrial equipment and mechanical devices. It bears the radial load, axial load and moment load under the rotating motion, and plays the role of support and rotation. The following will introduce the structure, working principle, application field and maintenance of the rotary support bearing in detail.Rotary support bearings are usually composed of an inner ring, an outer ring, a rolling element (ball, roller, etc.) and a cage.

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.

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.

High Rigidity Type Crossed Roller Bearing V has a solid one-piece construction for both inner and outer rings. Therefore, high accuracy and high rigidity are achieved, and mounting errors can be minimized. As separators are incorporated between the cylindrical rollers for smooth rotation, these bearings are suitable for applications where rotation speed is comparatively high.

Construction machinery bearings have the following characteristics and scope of application:High strength and wear resistance: Construction machinery bearings usually need to withstand high speed and high load, and work in harsh environments, so they need to have high strength and wear resistance.High temperature resistance: Construction machinery bearings usually work in high temperature environments, so they need to have good high temperature resistance to ensure that bearings can still operate normally at high temperatures.High rotation accuracy: Construction machinery bearings require high

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.

When the rotary help bearing is working, the internal and outer rings recognize relative rotation thru the aggregate of rolling elements. When the exterior pressure acts on the bearing, the load is transmitted to the internal and outer rings, and is transmitted to every different via the rolling element, attaining the carrying capacity.

In general, the rotary support bearing is an indispensable part of modern mechanical equipment, and its stability, reliability and life directly affect the operating efficiency and safety of the equipment. Therefore, in the process of engineering design and use, it is necessary to attach great importance to the selection, installation and maintenance of rotary support bearings to ensure the normal operation of the equipment and extend the service life.

The outer ring of the needle roller bearing is precisely stamped with thin steel plate, which has small structural space and large load capacity. It is suitable for occasions where installation space is limited and housing holes are not suitable for raceway.

The process has been continuously improved, and in insulated bearings, there is a coating 100μm thick on the surface of the outer or inner ring, which can withstand voltages up to 1000 V DC.

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.

In order to ensure the performance and service life of rotary support bearings, it is necessary to pay attention to the following points: correct selection of suitable bearing models and specifications, reasonable design and arrangement of bearing bearings and lubrication systems, regular inspection and maintenance of bearings, timely replacement of severely worn parts, to avoid overload and overspeed operation, to prevent dust and dirt intrusion into the bearing interior.

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.

The structural design of the stud CAM follower needle bearing consists of an end plate integrated into the inner ring (stud) and another inner shoulder ring pressed against the stud. In this design, both ends of the stud have lubrication holes to ensure that the bearing can be fully lubricated during operation. The inner ring is hardened by induction, which can improve the hardness and wear resistance of the inner ring, thus extending the service life of the bearing.

Construction machinery bearing is a mechanical component used to support and turn rotating parts. In construction machinery, bearings usually carry high-speed rotating parts, such as engines, transmission systems, etc. Bearings usually consist of an inner ring, an outer ring, a rolling element and a retainer.There are many types of construction machinery bearings, including rolling bearings and plain bearings. Rolling bearings reduce friction and improve rotation efficiency by rolling rolling elements (such as spheres, rollers or cylinders) between the inner and outer rings.

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.

Tapered roller bearings are separate bearings. Both the inner and outer rings of the bearing have tapered raceways. This type of bearing is divided into single, double and four-row tapered roller bearings according to the number of rollers installed. Single-row tapered roller bearings can support radial loads and axial loads in one direction.The type code of tapered roller bearings is 30,000, and tapered roller bearings are separable bearings.
