Plain plain bearings differ from more common rolling bearings in that their working surface (rather than rollers or balls placed between the inner and outer rings) acts as the supporting surface. The space between the bushing and the shaft is usually lubricated with a suitable type of lubricant, which improves rotational efficiency.
Plain bearings are an excellent choice over rolling bearings due to their compactness and low weight.
Plain plain bearings are generally most effective at low loads and speeds, and when precision requirements are less stringent. They are affordable and easy to use, and their installation is not particularly difficult.
National Standard spherical plain bearings are recommended for transmitting and receiving axial, radial and mixed loads in various connecting units of equipment - both moving and stationary. This helps to extend the life and improve the performance of the equipment.
National Standard spherical bearings, also known as sliding bushings, are produced in the cities of Kharkov, Dnepr, Kyiv from a variety of metals and alloys, as well as plastic, polymers, composites, graphite and carbon.
Features of spherical bearings
National Standard spherical plain bearings provide the necessary friction when sliding surfaces in contact with each other. There are four types of sliding for these parts, depending on the design of the shaft on which they are installed: in a dry environment, in a liquid environment, boundary sliding and gas-dynamic sliding. The choice of lubricant type depends on the shaft rotation speed and operating conditions. Lubrication is carried out with various types of lubricants: plastic, solid, liquid and gaseous.
It must be remembered that spherical bearings are divided into two types according to the lubrication method. The choice of lubrication method depends on the material of the sliding surface.
- Requiring lubrication during operation (with a steel/steel sliding surface);
- Self-lubricating, not requiring external lubrication (with a sliding surface: steel/metal fluoroplastic, steel/organofiber).
Advantages of using spherical bearings
- Working in conditions of high dust and lack of lubrication
- High reliability in high-speed drives
- Silent operation
- Compact dimensions
- Withstands vibration and shock loads
- Simple and reliable design
- Working in water, including rivers
- Economical
- Adjustment of the gap and precise installation of the shaft axis
