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.

Excavator bearing installation and removal methods, should be according to the excavator bearing structure, size and excavator bearing parts with the nature.Installation, disassembly pressure should be directly added to the end face of tight fit excavator bearing stalls circle, not by the excavator bearing rolling elements to transmit pressure, because this will be caused by the excavator bearing work surface indentation, impact excavator bearing normal workeven make excavator bearing damage.

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.

The single-row four-point contact ball slewing bearing has the characteristics of compact structure and light weight, which makes it widely used in construction machinery. Because the steel ball and the circular raceway contact at four points, this support can bear axial force, radial force and heeling moment at the same time, with high bearing capacity and stability. Applicable scope includes rotary conveyor, welding operator, small and medium-sized cranes, excavators and other construction machinery, is a multi-functional, efficient slewing support structure.

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.

Rotary bearing is an important mechanical component used to support and rotate shafts, which is usually used in industrial equipment, ships, automobiles and construction machinery. It is mainly composed of an inner and outer ring, a rolling body and a cage, and realizes the rotation and support of the shaft by rolling between the inner and outer rings of the rolling body. The design and selection of rotary bearing have an important influence on the stability, reliability and operation efficiency of the equipment.

The important construction modes of the turntable bearing seat are: four-point contact ball bearing seat, double-row angular contact thrust ball bearing seat, interpenetrating cylindrical roller bearing seat, interpenetrating tapered roller bearing seat, and three-row cylindrical roller with turntable bearing seat.According to whether the gear can be carried and the spread of the gear is divided into: toothless, external or internal gear and other different structures.The four-point contact ball turntable bearing seat has a higher static bearing capacity, the interspersed cylindrical roller be

The turntable bearing seat is a kind of large and extra-large bearing seat which can accept comprehensive load and has the characteristics of compact structure, sensitive rotation and convenient maintenance.

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

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.

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.

The outer diameter (OD) of the cam follower (stud or yoke) can be the standard cylindrical shape or be crowned. Crowned cam followers are used to keep the load evenly distributed if it deflects or if there is any misalignment between the follower and the followed surface. They are also used in turntable type applications to reduce skidding. Crowned followers can compensate for up to 0.5° of misalignment, while a cylindrical OD can only tolerate 0.06°. The only disadvantage is that they cannot bear as much load because of higher stresses.

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.

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.

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.

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.

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.

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.
