3. What Is the Material Used in Bimetal Bushing?

In bimetal bearings, you can choose two metal alloys of your desire.

Mainly, metal such as bronze and copper are used for layering the bimetal bushes. A bronze sliding layer is usually wrapped around a two-layered bimetal bearing.

You can layer the bimetal bushing with stainless steel, carbon steel, or bronze.

Heavyweights and stress loading conditions are no match for bimetal bearings. It has a high capacity for carrying loads.

Our anti-corrosion bimetal bearings manufactured at Bushing MFG are very simple to operate.

 Low carbon steel is used as the base material in bimetal bearings. It is also covered with copper or tin plating on the exterior surface.

Customers can also choose high tin aluminum alloy for layers or any suitable copper layer material.

Bushing MFG can do the thickness of the alloy layer and sintering of any thickness according to the client’s need. However, the standard thickness is 0.25mm-0.3mm.

Inner wall copper layer material is generally CuSn6Zn6Pb3 or CusN6.5P0.1. (i.e., two kinds of tin bronze and two types of lead bronze.)

Four kinds of copper and lead/bronze alloys can be used for making layers in bimetal bearings.

CuPb24Sn4 (Copper, Lead, and Tin): 

  • It has a high fatigue strength and bearing capacity.
  • Impact resistance,
  • Due to the high lead content in the alloy and high density, it is prone to lead segregation, which reduces the abrasion resistance of the bushing.
  • It may also reduce the strength of the combination of alloy layer and steel back.
  • The high-cost copper layer is used in high speed, swing, and rotating wages under bearing conditions.


  • It has good lubrication performance, wear resistance, and corrosion resistance.
  • Suitable for medium to high speed and has a more significant impact on load-bearing.
  • The gasket surface pressure is high.
  • There is the lateral pressure of the sliding bearing, such as the bimetallic bearing shell, the piston pin set, lining, etc.

CuSn6Zn6Pb3 (Copper, Tin, Zinc, and Lead):

This material allows the bearing to work under general load and medium sliding speed, such as turbines, motors, compressors, piston clutches, connecting rod bushings, rocker arm bushings, and so on.

5. What Are Self-Lubricating Bimetal Bearings?

One of the oil-free or self-lubricating bearings is the bimetal bearing.

Bimetal bearings are made of a high-quality low-carbon steel backing with a lead-tin-bronze alloy sintered on the surface.

 It is a bimetal merged with copper and steel after much high-temperature sintering and dense rolling processes.

Bimetal bearings are a new type of lubricating bearing that combines the advantages of metal bearings and self-lubricating bearings.

The weight is supported by the metal base, which is lubricated using a specially developed solid lubricant.

It has a high load-bearing capacity and is impact-resistant.

It has high-temperature resistance and has an excellent self-lubricating ability.

It’s especially well-suited to situations where lubrication and formation of an oil film are problematic, such as oversized loads, low speeds, reciprocation, or swing.

It also has resistance against water erosion and other acid solutions.

12. What Are the Various Types of Bimetal Bearings?

Bimetal bearings have three main types.

These types include:

Flange bushes

  • Flange bearings, also known as flange bushings, are bronze sintered, oil-impregnated bushings with a load-bearing flange.
  • Flange bushings are utilized at lower speeds and with lighter stresses since the mating shaft can still travel freely within the bushing.
  • Flange bearings contain a flange on one end that acts as a load-bearing surface for axial loads, similar to cylindrical sleeve bearings.
  • Agriculture, aerospace, automobile applications, and appliances, machine tools, and hydraulics all employ them.
  • These bushes allow the shaft assembly to glide within the bearing freely.
  • Sizes of flange bearings are available in both metric and imperial measurements.
  • It doesn’t need to be greased or oiled regularly.
  • Other components can use the flange as a load-bearing surface.

Thrust Washers

  • Flat washers that sit between a revolving surface and a fixed component are known as thrust washers.
  • They restrict movement along a shaft by supporting the axial load or side to side motion.
  • The thrust washer serves as a support surface for the bearing.
  • Axle assemblies, motors, transmissions, pumps, power take-offs, and winches are high-wear applications.
  • Almost every application necessitates the use of a wear surface.
  • The application determines the material of the thrust washer.
  • Several factors influence the material selection, including speed, load, and temperature.
  • Plastic, brass, bronze, stainless steel, graphite, and other materials make thrust washers. Low and high carbon steel is used to make the bulk of thrust washers.
  • Carbon steel can be case hardened or hardened all the way through.

13. What Is the Function of Bimetal Bearings?

Bimetal bearings have three main functions.

To Reduce Friction

The hindrance to motion between two objects that are in contact is called friction.

For the objects to move smoothly, friction is needed to be removed.

There are two types of friction, rolling and sliding friction. Since bearings also roll and slide, they also need to be free of friction.

Some bearings are made to handle rolling friction, and some are made to take sliding friction. Bimetal bearing, on the other hand, handles both types of frictions.

Although bearings are designed to reduce frictions, they cannot eliminate them.

For this purpose, bearings need lubrication.

Bimetal bearings produced at Bushing MFG are self-lubricating and reduce friction quickly.

Carry Loads

In addition, to reduce friction, a bearing must be able to carry loads.

Loads are placed on the bearings by the shaft or other moving parts. They can also be axial and radial.

Bimetal bearing successfully carries the load of the shaft and other moving elements within the machine.

Bearings to Carry Heavy Loads

Bearings to Carry Heavy Loads

Position Elements

Another function of the bimetal bearing is to position a moving element such as a shaft.

To do this, the bimetal bearing is designed to resist movements in one or more directions.

The bimetal bearings only allow the movement in the right direction.

In some cases, the consequences of shaft movement other than rotation can be severe, and this movement can badly damage the machine.

Wear resistance is a significant feature in bimetal bushings, even though their uses differ widely.
