The operating principle of bronze bushings and other solid bearings

Bronze bushings, like many other pure metal bushings, are based on so-called alloys. In this process, metal “blends” are created by melting different types of metal, which in turn have different specifications. Hence, it is difficult to directly compare these different alloys to the large number of different polymer compounds commonly found in polymer bearings. Nevertheless, this blog post should help to better differentiate between the two technologies and to make a decision for or against one of them. Working principle of solid bearing such as bronze bushing.

Bronze bushing belongs to solid bushing or solid bearing group. They are composed of a single material or alloy. Similar to solid plastic bushings, there is no sliding or support layer. What all metal alloys have in common is their limited applicability as sliding materials. Combined with the metal shaft, it is important for all solid bushings that are subjected to constant stress. Provides cooling and reduces friction by providing lubricants.

 

The problem is: without an external supply of lubrication, metal solid bearings are only suitable for so-called emergency operations at best. In practice, there is talk of emergency operation when the casing can continue to run long enough to allow immediate shutdown of the unit when power is interrupted. An example of these emergency operation functions is a pump whose bearings are usually designed to be lubricated and cooled by the medium being pumped.

 

This need for permanent lubrication led to design requirements for components. This is why bronze bushings and other solid bearings have so-called lubrication grooves. These are milling or turning channels extending along the inner and/or outer diameters through which lubricants can be distributed to bearing points. However, these bushings are very expensive to produce, especially in large quantities, as the lubrication groove must be made separately on a suitable milling machine or lathe.

Technical specification for bronze bushing and solid bearing

The possible combinations of different metals are varied, not only because of the choice of base metals and their combinations but also because these metals can be used in different proportions. Given this diversity and lack of metallurgical detail, detailed comparisons are beyond the scope of this blog. However, here is a rough overview of some common alloys and their specifications:

CuSn7Zn4Pb7- Bronze DIN EN 1982 (CC493K)

The most common and cost-effective red bronze (bronze) alloy is used for plain bearings.
Good emergency operation and adequate wear resistance under moderate load.
Also suitable for unhardened shafts and light edge pressures.

CuSn12-C

Tough bearing material with good sliding properties and good wear resistanceEspecially suitable for high surface pressures and simultaneous shocks

CuSn8

Very good sliding properties, high wear resistance, and good heat resistance.
Suitable for high speed and high load if well lubricated and with hardened shaft
Especially suitable for thin-wall bushings
Depending on its specifications, there are many other variants suitable for a wide range of applications.
Bronze bushing compared with plastic bushing
It is difficult to make a meaningful comparison between the two material groups purely on the basis of individual technical values. Like most metal bushings, bushings made of bronze or similar alloys have higher mechanical strength values and — at least when lubricated — better PV values. Therefore, frame conditions should be considered first. For example, polymer bushings can often be cost-saving because lubrication may not be required and are more cost-effective to produce. In addition, depending on the polymer compound, the pure material cost can also be significantly more cost-effective. Eliminating the need for external supply lubrication also brings further advantages in bushing reliability and maintenance. In addition,

benefits

Higher intensity values
Better PV value (if lubricated)
May have higher surface velocity (if lubricated)
disadvantages

Need lubrication
More complex and therefore more expensive to manufacture (lubrication grooves or holes)
Increase the weight
Corrosion resistance (depends on the alloy)
Non-Rohs (depends on the alloy)

Looking for the best plain bearing? We are happy to help you!

In every plain bearing application, these advantages and disadvantages must be weighed. However, not all of these aspects play a role in every application. In addition to bronze bushing, bronze bushing or other solid bearings, there are other bearing types that have other advantages and disadvantages.
Different types of plain bearings are suitable for different applications with different specifications. There is often application overlap – but it is not uncommon to see significant differences in life and performance.
Our application specialists will be happy to advise you and design your bearing point with you. We will identify common casing for you with the best service life, cost and performance ratio – by phone, digital access or in your field. Free and no obligation. Everything comes from one source.
