An Overview about Sleeve Bearings and Their Applications

March 12, 2021

Bearings are hardware components that can effectively support the rotation of a shaft. They are primarily used in a lot of machines and appliances that utilise shafts for rotation purposes. Some products that utilise bearings include automobiles, aeroplanes, and generators.

What makes bearings important for these products is that they can effectively reduce the friction of the rotating shaft and the part that supports its rotation. They can likewise ensure that the rotation will be smooth and effortless, which would consequently cut down overall energy consumption. Bearings are also significant to many applications since they can effectively protect the part that supports the rotation. They even maintain the positioning of the rotating shaft and other associated components.

Today, there are several types of bearings that industries can maximise. One of these types is the sleeve bearings. Sleeve bearings boast some great features that make them suitable for certain applications.

Features and Highlights

Sleeve bearings are comprised of a smooth sleeve that is situated between a bore and an axle. The sleeve of these bearings can be made from metal, plastic, or fibre-reinforced composite. A liquid or particulate lubricant, alternatively, is often fitted between the journal and the axle. The whole composition of sleeve bearings allows them to effectively reduce vibrations and noise, given that they can easily absorb friction between two moving surfaces or parts as they perform sliding actions.

The sleeve bearings can be fabricated out of bronze, steel, stainless steel, brass, or plastic. And from these materials, there are two designs available for sleeve bearings. One of these designs is the flanged sleeve bearings. These bearings have a protruding flange at one end of the sleeve, helping them obtain a bearing surface for an axial load. Another design of sleeve bearings is the cylindrical bearings. Cylindrical bearings are normally horizontally split, utilising lubricant that is being provided through axial grooves.

The general composition and structure of sleeve bearings allow them to provide great features to certain industries. They can certainly help in reducing noise and vibration. They likewise offer greater shock load resistance, lower overall costs, less maintenance, and easier installation. 

Industrial Applications

With all the features available with sleeve bearings, many industries install them in different products for them to carry out different functions and applications.

For the automotive industry, sleeve bearings are utilised in transmission shafts, links, pins, and crank components. They are likewise used for alternators, steering gears, pumps, wheels, and suspension. As for the agriculture industry, linkage assemblies on attachments and steering gears all maximise the features of sleeve bearings. Food process and packaging also utilise sleeve bearings by installing them on conveyors and filling devices.
