Spacer sleeves – how do they work?

Spacer sleeves, also known as through sleeves, are not impressive in size, but it is difficult to imagine any smoothly running machine without them. These parts have a body with a circular or hexagonal (hexagonal) cross-section and mounting elements on one or both sides: internal threads, external threads, snaps, or combinations thereof.

The task of spacer sleeves, as the name implies, is to provide a constant distance between components to ensure the proper functioning of entire systems.  The length of the bushing body defines the distance between components of the structure. In addition, spacer sleeves are also used to reduce friction, control movement, or provide adequate insulation. They are installed in small everyday devices, as well as in vehicles and even advanced production lines.

Spacer sleeves - function

Types of spacer sleeves

Since spacer sleeves are used in various mechanisms, they must have the right parameters regarding shape and size. When choosing the right one, other equally important factors should be considered, such as strength, corrosion resistance, electrical insulation, weight, operating temperature, or vibration and noise absorption. Hence, the material used to make through-hole sleeves is extremely important. Typically, stainless steel, aluminum, and brass are used for their manufacturing. Nevertheless, they can also be made of plastic and even rubber.

Application of spacer sleeves

Spacer sleeves are an integral part of modern technology. Thanks to these inconspicuous parts, it is possible to use functional devices with which it is easier to imagine daily life. Spacer sleeves prove that seemingly complex structures consist of many simple solutions. Where can they be found, and what functions do they perform?

  • Electronics – bushings are important in smartphones, TVs, and computers. They ensure the proper distance (isolation) of circuit components because too little distance between components can interfere with operation by overheating or creating short circuits.
  • Domestic appliances – in washing machines or dishwashers, spacer bushings reduce friction and provide adequate insulation, which is key to maintaining proper operation of mechanisms.
  • Furniture – spacer sleeves help create and maintain proper spacing between components of a structure, thus ensuring its stability and strength.
  • Pumps and compressors – the spacer bushings used in them help maintain proper spacing between moving parts, enabling smooth and trouble-free operation.
  • Bicycles – found in steering and suspension, spacer sleeves reduce friction and ensure proper, smooth operation of mechanisms, which impacts riding safety.
  • Cars – in the automotive industry, for example, spacer bushings are used in the suspension and steering system, which help absorb vibrations and maintain proper distances between moving system components.
