Bearings are friction components that are loaded when they come into contact with and move relative to another part. The movement can be sliding or rotating. There are basically two types of bearings: sliding bearings and rolling bearings. Other types of bearings include fluid bearings that support their load on a thin layer of gas or liquid. Magnetic bearings that use a magnetic field to carry the load; hinged flexural bearings in which the load is supported by a bent element; and jeweled bearings used in clocks and watches.

Sliding bearings, also called bushings, sleeves or sleeve bearings, are usually cylindrical in shape and do not contain moving parts. Standard configurations include cylindrical bearings for radial loads, flanged bearings for radial and light axial loads, thrust spacers and flanged spacers for heavy axial loads, and sliding blocks of various shapes. They can also be custom designed to include special shapes, features (deep grooves, oil holes, notches, projections, etc.) and dimensions. Sliding bearings are used for sliding, rotary, oscillating or reciprocating movements. In sliding applications, they are used as plain bearings, bearing strips and wear plates. In these applications, the sliding surface is usually flat, but can also be cylindrical, and the motion is always linear, not rotational. Rotational applications involve cylindrical surfaces and one or two directions of travel. Oscillating and reciprocating applications are flat or cylindrical surfaces, but travel in both directions. Sliding bearings can be constructed as solid or split (wound bearings) for ease of mounting. Matching the bearing to the application is important. High loads require bearings with larger contact areas and high load carrying capacity. Bearing designs with solid lubricants can operate at higher temperatures than oil/grease lubricated bearings. High speed applications require special lubricants to minimize heat buildup and friction. Sliding bearings are manufactured with different configurations and product selection depends on the operating conditions and performance requirements of the application.

Sliding bearings are the counterpart to the widely known and widely used ball bearings. Motion applications using bearings for motion applications can be found in every industry: slow and fast applications, light and heavy applications, abrasive and clean applications

Applications： Each industry has its own preference for the type of bearing used for each application.

First, it’s important to understand the basic differences between thin-walled plastic bushings and thick-walled bronze bushings. The standard wall thickness of a thick-walled bronze bushing is between 1,50 and 4,00 mm. In contrast, the wall thickness of plastic bushings is much thinner, usually between 1 mm and 1.5 mm. Due to the thin wall, the bushings not only have many benefits, but also perform just as well, if not better, than thick-walled bushings. Thin-walled bearings with thick-walled bushings have a thin wall, while bronze bushings usually have a thicker wall.

In many cases, the application will benefit from using a thin-walled bushing instead of a thick-walled bushing. For example, a wrapped cusn8 bronze bushing is designed with a thinner wall, and a steel backed bronze bushing for better heat dissipation. Heat buildup increases the amount of wear on the bushing, and it is critical that the heat be able to dissipate through the shaft and housing. Excessive heat buildup is more likely for thick-walled bronze bushings.

The better the heat dissipation of the bushing, the higher the PV allowed. Higher PV values allow the bushing to handle more speed and load combinations. In addition, thin-walled bushings are able to hold tighter tolerances. They also have less opportunity for deformation, which is common in thick-walled bushings. Finally, thin-walled bushings are ideal for applications where weight and fuel economy are an issue, such as in race cars, snowmobiles, automobiles and motorcycles. Thin wall bushing materials are lighter in weight, reducing costs and freight.

Are thin-walled bushings not as strong as thick-walled bronze bushings? The wall thickness of any bushing is not directly related to its strength. Other more important factors that should be considered include the weight, coefficient of friction and wear capacity of the bushing. Thin-walled bushings have a shorter life than thick-walled bronze bushings. It is reasonable to assume that because the bushing has less material (thinner walls); it will not last as long as a thick-walled bronze bushing. This is incorrect because the thin walls of the thin-walled bushing help dissipate any heat build-up, which actually prevents wear.

Bronze bushings are designed with thicker walls to compensate for wear, but even with the added material, the bushing surfaces are still prone to wear. In high speed applications, constant relubrication of the bushings will help prevent wear. However, if bronze bushings are used to facilitate other types of motion; excessive wear can lead to increased clearance between the shaft and bearing. If this happens, a number of problems can occur. It is important to remember that wear depends on the composition of the bushing material, not the wall thickness. For this reason, VIIPLUS continues to develop new metallic self-lubricating bearing sliding materials to minimize wear and provide long-lasting, maintenance-free solutions for a variety of applications.
