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.

In engineering applications, rotary support bearings play an important role. For example, in construction machinery, rotary support bearings are widely used in cranes, tower cranes, excavators and other equipment to support and rotate various arms, booms and rotating seats to ensure smooth operation and accurate positioning of equipment. In ships and port machinery, rotary support bearings are used to support various rotating devices to help ships navigate and cargo handling.

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.

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.

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.

The ball screw pair has the characteristics of high precision, reversibility and high efficiency, which is the further extension and development of the ladder screw, and the important significance of this development is to change the sliding action of the ladder screw into a rolling action.

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.

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.

These bearings are widely used in the rotating parts of industrial robots, machine tools, medical equipment, etc., which requirecompactness, high rigidity and high rotational accuracy. In addition, bearings made of stainless steel and those with inner and outer rings provided with mounting holes are also available on request. Please contact us.Crossed Roller Bearings are compact bearings with their rollers alternately crossed at right angles to each other between inner and outer rings.

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.

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.

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.

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.
