What is the difference between rolling bearings and slewing bearings?

Rolling bearings and slew bearings are both types of bearings. They have many similarities in application, but there are also some obvious differences between them. Rolling bearing is a mechanical component that bears load during rolling motion and is widely used in various mechanical equipment. A slew bearing is a special type of bearing with a combined radial and axial load capacity, often used to support rotating shafts or rotary-linear motion hybrids. The two mainly differ in the following aspects:

  1. Structural characteristics

The structural features of rolling bearings include balls, inner rings, outer rings, cages and other components. The inner ring is closely matched with the shaft, and the outer ring is matched with the bearing seat. The cage separates the balls and distributes them evenly. Rolling bearings have the advantages of small friction coefficient, low vibration and noise, but they also have maintenance requirements.

The structural features of slew bearings include outer rings, inner rings, rolling elements (balls or rollers) and cages. The outer ring can be an integral structure or a segmented structure, and the inner ring is closely matched with the shaft. Slewing bearings can bear both radial and axial loads, and have high rotation accuracy and axial load-bearing capacity. Slewing bearings have a long service life and are suitable for high-speed, high-precision mechanical equipment.

  1. Application scope

The application range of rolling bearings is very wide, involving almost all types of mechanical equipment, such as machine tools, automobiles, aircraft, ships, etc. There are many types of rolling bearings, and the appropriate bearing type can be selected according to different loads, speeds, accuracy and speed ranges.

The application range of slew bearings is relatively narrow and is mainly used in robotic arms, packaging machinery, machine tool equipment, plastic machinery, steel rolling equipment and other fields. The characteristics of high precision, high rigidity and high load-bearing capacity of slew bearings make them an indispensable part of these high-precision mechanical equipment.

  1. Load characteristics

The load properties of rolling bearings are generally radial load or axial load, but some special types of rolling bearings such as angular contact ball bearings can withstand combined radial and axial loads. The nature of the load depends on the bearing’s structural design and application.

The load properties of slew plate bearings are mixed radial and axial loads. This load characteristic gives slew plate bearings unique advantages in supporting rotating shafts or rotation-linear motion hybrids.

  1. Rotation accuracy

The rotation accuracy of rolling bearings depends on their manufacturing quality, the function of the cage, and the maintenance during use. Under continuous load, the rotation accuracy of rolling bearings is prone to change.

The rotation accuracy of the turntable bearing is relatively high, and it can maintain high accuracy even under high-speed rotation. This is because the structural design of the slew bearing helps reduce friction and vibration, thereby maintaining stable rotation accuracy.

There are obvious differences between rolling bearings and slew bearings in terms of structural characteristics, load characteristics, and rotation accuracy. Rolling bearings are suitable for various mechanical equipment and have the advantages of small friction coefficient, low vibration and noise, but they require regular maintenance. Slewing bearings are suitable for high-precision mechanical equipment that supports rotating shafts or rotation-linear motion hybrids. They have the characteristics of high precision, high rigidity and high load-bearing capacity. When selecting bearings, the most suitable bearing type should be selected based on the characteristics and requirements of the specific application.

Things to note when choosing bearing lubricant

Bearing lubricant analysis is crucial to maintaining normal operation of bearings. Its main functions are as follows:

  1. Reduce friction and wear: Lubricating oil generates an oil film on the bearing surface, reducing friction and wear between the bearing, the shaft and the bearing seat, thereby extending the bearing life.
  2. Prevent rust and corrosion: Lubricating oil can prevent the bearing surface from being eroded by water, gas and other substances, and avoid rust and damage problems.
  3. Give full play to heat dissipation efficiency: In high-speed or high-temperature environments, lubricating oil effectively takes away the heat generated by the bearing, reduces the operating temperature of the bearing, and improves its working performance and stability.
  4. Has a cleaning function: Lubricating oil helps clean dirt and impurities on the bearing surface, prevents them from invading the bearing structure, and protects its normal operation.
  5. It also has sealing and waterproof functions: The lubricating oil builds a sealing area between the bearings, blocking external clutter and moisture from entering, ensuring the bearing’s leak-proof and sealing performance.

In order to ensure the normal operation of bearings, extend the overhaul cycle and improve work efficiency and reliability, it is crucial to select the appropriate lubricant. Based on the above functions, the following factors should be focused on when selecting lubricants:

  1. Suitable viscosity: The viscosity of lubricating oil has a direct impact on its fluidity and lubrication effect. The selection should be based on characteristics such as bearing pressure, speed and temperature, and should be maintained within a moderate range.
  2. Excellent oxidation stability: Bearing lubricating oil must have good oxygen resistance. Because it is easily oxidized by oxygen when left in the atmosphere for a long time, the performance of the lubricating oil will be damaged or even invalid. Therefore, lubricants with good antioxidant properties are preferred.
  3. Excellent anti-rust ability: The anti-rust properties of lubricating oil are related to the service life of the bearing. The added antioxidants can form a protective layer on the bearing surface to prevent it from being corroded, thus extending the bearing life.
  4. Excellent anti-foaming property: During the startup and operation of the machine, the lubricating oil will generate bubbles due to stirring. Such foam will weaken the lubrication effect and seriously shorten the bearing life. Therefore, it is crucial to choose a lubricant with good anti-foam properties.
  5. Good oil-water separation performance: In actual operation, lubricating oil will inevitably come into contact with water. If oil and water cannot be effectively separated, the lubricating oil will easily fail. Therefore, it is particularly necessary to choose lubricating oil with excellent oil-water separation ability.

In summary, when selecting bearing lubricants, multiple factors need to be weighed, such as appropriate viscosity, excellent antioxidant stability, excellent rust prevention capabilities, excellent anti-foaming properties, and excellent oil-water separation performance. In the process of selecting and using lubricants, it is necessary to fully combine the actual situation and comprehensively consider these factors in order to select the lubricant that best meets the requirements, so as to ensure the normal operation of the bearing and extend the service life.
