slewing ring

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.

1.Capable of withstanding various loads, with the highest load-bearing capacity among the four structures 2.The axial and radial dimensions are relatively large, and the structure is sturdy 3.Especially suitable for heavy-duty machinery that requires larger diameters, such as cranes, ladle turntables, and other machinery

1.Easy to assemble, able to withstand large axial forces and overturning moments 2.Customizable structure, tight structure, special design of raceway 3.Suitable for loading and unloading machinery with a diameter of medium or above

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.

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. With good moment, thrust and radial loading capacity. 2. Suitable for light to medium duty. 3. Easy installation 4. light weight and thin section 5. Flexible rotation

Flange slewing bearings are light in weight, thin in thickness, and flexible in movement. It is widely used in food machinery, filling machinery, environmental protection machinery, etc. The flange slewing ring bearing mainly includes outer and inner rings, grease fittings, sealing strips, gaskets, load plugs and taper pins, and its characteristics are: both the inner and outer rings are L-shaped; the sides of the rings are provided with grease cups, and the outer Steel balls are assembled between the ring and the inner ring. Each ball is separated by a spacer, and the steel ball and the spacer are installed through a load plug and a tapered pin to protect the running of the ball.

With the development of intelligence and mechanization in the smelting industry, it provides irreplaceable huge business opportunities for the application of slewing bearings. Because it can be used in robotic arms, fully automatic intelligent robots, ladle rotary tables and other industries. Therefore, flexible mechanical equipment will become the general trend of many factories. The rotary table is composed of arm system software, fixed tower, rotating drive and other components. It is typically a light-loaded low-speed turning machine. The slewing bearing of the rotary metallurgical furnace generally uses a three-row roller structure slewing bearing. This structural product is a slewing bearing with high bearing capacity, which is mainly used in the operation with a large load. It is composed of three ferrules, the upper and lower rows of rollers are horizontally distributed, and the radial force is borne by the three rows of rollers arranged vertically, so it can bear the axial force and tilting moment from two directions. This kind of large three rower slewing bearing is our featured product with advantages of high load, high precision and long service life.
