Подшипник скольжения: основная поддержка механической работы, Лоян INNO Bearing объясняет это для вас
Slewing bearings, also often called turntable bearings, are also called rotating bearings or slewing bearings by some people. They are new mechanical parts that have gradually emerged worldwide in the past forty years. Slewing bearings are mainly composed of inner and outer rings, rolling elements, etc. Although their structure seems simple, they contain huge energy.
One of the biggest features of slewing bearings is that they can withstand comprehensive loads. They can withstand large axial, radial loads and overturning moments at the same time, which makes them an indispensable key component in many mechanical equipment. Moreover, slewing bearings generally have mounting holes, internal or external gears, lubricating oil holes and sealing devices. These ingenious designs make the host design more compact, the installation guide becomes simple, and the later maintenance is easier.
The slewing bearing family is very large, with four series of gearless, external and internal gear 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. Each series has unique performance advantages. For example, four-point contact ball bearings have a high static load capacity and can stably support the equipment to withstand high pressure in a stationary state; cross cylindrical rollers have a high dynamic load capacity and can cope with frequent dynamic loads during the operation of the equipment; the pre-interference of cross tapered roller bearings can make the bearings have greater support rigidity and rotation accuracy, ensuring the accuracy of equipment operation; the three-row cylindrical roller combination bearings are led to the height of the bearings due to the increase in load-bearing capacity, and various forces are borne by different raceways respectively, so under the same force conditions, the bearing diameter can be greatly reduced, making the host design more compact.
Wide application fields of slewing bearings

The application fields of slewing bearings are extremely wide, covering almost all industrial fields.
In the field of construction and engineering, slewing bearings can be called “pillars”. Engineering machinery such as tower cranes, cranes, and concrete pump trucks are carrying out heavy operations every day. These equipment need to have strong load-bearing capacity and extremely high reliability, and slewing bearings can perfectly meet these requirements to ensure safe, stable and efficient operation of the equipment. At the same time, slewing bearings also play a fundamental supporting and rotating role in the fields of bridge construction, shipbuilding, and ship equipment.
The working environment in the metallurgical and mining fields is often very harsh, and the equipment needs to frequently withstand high-intensity workloads. With its excellent performance, slewing bearings perform well in mining equipment such as mine hoisting equipment, mine cars, and vibrating screens, and can ensure the normal operation of equipment in harsh environments. In metallurgical equipment, such as steelmaking equipment and cooling equipment, slewing bearings are also widely used to provide solid guarantees for the reliability and stability of the equipment.
The energy and chemical industries are also inseparable from the assistance of slewing bearings. In power generation equipment such as thermal power plants and hydropower plants, slewing bearings are used in key rotating parts such as steam turbines and water turbines to ensure that the equipment can operate efficiently and continuously supply electricity to the society. In chemical equipment, slewing bearings are also widely used in equipment such as reactors and agitators to ensure that the equipment can operate stably and safely in complex chemical production processes.
In the high-end aerospace field, slewing bearings play an even more vital role. In aircraft, satellites and other aerospace vehicles, slewing bearings are used to control rotating parts such as surface servos, antennas, and load compartments to ensure that these parts can rotate flexibly and operate stably, ensuring that the aerospace vehicles can perform various tasks normally.
In addition, slewing bearings are also widely used in daily life. For example, in wind power generation, the yaw bearings and pitch bearings of wind turbines are slewing bearings, which help wind turbines better capture wind energy. In the field of medical devices, large medical devices such as gamma knives, CT machines, and MRI machines also use the high precision, low noise, high life, and high reliability of slewing bearings to provide precise support for medical diagnosis and treatment.
