Slewing bearing is an important "joint" of the crane. Various loads and moments on the working device need to be transmitted to the chassis through the slewing bearing. Because the slewing bearing is overloaded, it is also the part where the crane is prone to failure, so it is necessary to install a new slewing bearing after long-term use. Truck cranes, crawler cranes and other heavy construction cranes are usually using large single row four-point contact ball slewing ring bearing. This type of slewing bearing can bear larger axial load, radial load and tilting moment, enabling crane to lift heavy loads stably and reliably.

Single-row crossed roller slewing bearing The single-row crossed roller slewing bearing is composed of two seat rings. It has a compact structure, light weight, small assembly clearance, and high requirements for installation accuracy. The rollers are arranged in a 1:1 cross, which can It can withstand axial force, overturning moment and large radial force at the same time, and is widely used in lifting, transportation and engineering machinery products.

The gear shaft is an important component in mechanical transmission. It transmits power and energy through the meshing of gears. torque. The gear shaft is the shaft on which the gear is installed. Its main function is to support the gear and connect the gear to the The rotational force is transmitted. The gear shaft is usually made of a long strip of metal material. Has certain strength and stiffness. The end of the gear shaft is connected to the driving device (such as a motor), The other end is connected to the driven device (such as mechanical equipment). When the drive unit rotates, by Due to the meshing effect of the gears, the rotational force of the driving wheel and the driven wheel will be transmitted along the gear shaft.

Slewing bearing ring shaft forgings are produced and processed by Luoyang Heng guan Bearing according to customer requirements.They are mainly used in modules,power plants,buildings,and locomotive.They have the same strength,light weight,high productivity,high flexibility,low raw material consumption,and high cost performance.Slewing shaft forgings can be used in slewing ring shaft bearing processing,medical equipment,aviation forging,and automobile industry.At present,the products sincerely welcome overseas customer to inquire and negotiate.

Excavator is one of the important equipment in modern engineering construction. The reason why the excavator can turn left and right in the work is inseparable from the credit of the slewing mechanism, which is one of the important components of the hydraulic excavator. The slewing mechanism is connected with the traveling device through a slewing bearing, and the slewing drive device makes the platform rotate relative to the traveling device, and drives the working device to rotate around its central axis of rotation. We are specialized in the production of engineering machinery slewing bearings, drive shafts and matched pinions. For some common model excavators slewing bearing, we have ready stock and can deliver within one week. Our company has a special quality testing laboratory, devoted to product design and development, product application and testing methods. At the same time, the company also has advanced production equipment and testing equipment to ensure that products have high performance, long life, low friction, high precision.

Medical equipments do not have high requirements on the load-carrying capacity of the slew ring, so the slew rings generally selected are characterized by lightness and small size. The slew ring selected for medical devices require high precision, including axial and radial clearances and surface precision, to ensure the accuracy of medical devices. The product we made has been finely ground to improve the precision, flexible rotation and high precision. It is mostly used in automated production lines, robot arms, bases, and medical machinery with stable quality.

1. The work is simple and sensitive, and the rotation resistance is small. 2. The structure is compact and the dimensions (mainly height) are small. 3. Convenient maintenance and long service life. 4. It is composed of ring gear, seal and screws, etc. It is easy to install and convenient for specialized centralized production. 5. There is no intermediate pivot, and other components can be installed in the middle space.

1)Selecting high-quality raw materials and strictly controlling the production process; 2) Using LF refining furnace and VD vacuum degassing furnace to ensure the internal quality of ring gear castings; 3) During the casting process, CAE simulation pouring software is used to assist the design process, so as to modify the pouring model in time , so as to better control the quality of the ring gear blank; 4) Large ring gear is fully tempered and quenched , so that it has good comprehensive mechanical properties, and has good plasticity and toughness while ensuring high strength. To provide customers with ring gear castings with high service life and high operating rate.

Select high quality 35CrMo, 42CrMo, C45 steel material, and alloy steel according to customer's requirements. Full production line for processing and can provide one to one customization service to customers. Support teeth quenching, teeth grinding, surface treatment like Carburizing，Nitriding etc. Good at high precision ring gears processing with professional inspection teams. Teeth precision 2, 3, 5, 7, 8 grade can be acheived perfectly.
