Solid Lubricant Bushing For The Aerospace Industry

Lubricants and greases that are too high or too low in viscosity will not function at extreme temperatures. Solid lubricant bushings, on the other hand, work well at extreme temperatures. Solid lubricant-embedded bronze bushings are therefore often used in cryogenic liquid hydrogen-oxygen rocket fuel systems.

Solid Lubricant Embedded Bronze Bushing

A turbopump forces the pressurized liquid fuel components into the engine, where they are ignited by an electric spark. The use of graphite as a solid lubricant forms a lubrication transfer film during friction. avoiding the fact that liquid lubricants can freeze and hydrocarbon lubricants can explode in this liquid fuel environment.

The Mechanism Of Solid Lubricant Material

The main purpose of solid lubrication is to adhere the solid lubricant on the friction surface to form a solid lubricating film by plating, coating, and other methods. During friction, a transfer film is formed on the surface of the dual material, so that friction occurs inside the lubricant, thereby reducing friction and wear.

  • On the one hand, the lubricating film can prevent direct contact between the surfaces of the paired materials
  • on the other hand, it can reduce the shear strength of the contacting thin layer, thereby significantly reducing the friction coefficient

The Benefit Of Solid Lubricant

The main role of a solid lubricant should be lubrication & Reducing friction

The constant friction within the solid lubricant bearing generates heat. Over time, this deteriorates the bearing and significantly shortens its life. Solid lubricants play an important role in separating moving parts, minimizing friction, and preventing continual wear.

Solid Lubricant Embedded Bronze to reduce corrosion and prevent contamination

Solid lubricants also play a role in reducing corrosion and preventing contaminants, increasing service life. Improve the function and reliability of each bearing and reduce the risk of corrosion-based failures by checking and regularly lubricating them during bearing maintenance.

Solid Bronze Bushing takes metal material as the base, and holes in the base (brass, tin bronze, aluminum bronze, cast iron, GCr15, and other alloy materials) are arranged in an orderly and appropriate size, and then embed oily graphite, PTFE, molybdenum disulfide particles as solid lubricating material.

When the bearing works under oil-free lubrication conditions, due to the effect of frictional heat, the solid lubricating material will gradually be transferred to the working surface of the friction pair, thereby reducing the friction factor.

This type of solid lubricant-embedded bronze will keep contaminants out, and it is compatible with acids and other corrosive chemicals. As such, it functions well in wash-down applications.

Properties Of Solid Lubricant – Learn More!

1. Easy shearability

One of the purposes of using a solid lubricant is to reduce friction, So the solid lubricant must have a slip surface that is easy to slide.

2. Easy to adhere

To maintain the performance of solid lubricant for a long time, the solid lubricant must have the property of easy adhesion to the anti-friction surface, and be able to shear sufficiently until the lubricating effect disappears.

3. Wide temperature range

The nature of solid lubricant does not change in a wide temperature range, so it can be applied to a wider range of applications.

4. They are also required to be non-toxic and non-hazardous.

Graphite Embedded Bronze Bushing At

Our solid lubricant bushing selection ranges from simple sleeve bushings to more complex styles that can incorporate notches, grooves, or metal reinforced sleeves.

High-quality plugged materials are made from graphite materials because they offer superior strength, hardness, and wear-resistant that carbon is known for as well as the lubricity that graphite is known for.

How to improve the performance of graphite solid lubricants

Graphite is the best choice as a solid lubricant because it is robust, thermally stable, and inert in most chemical and corrosive applications. Where better wear performance is required, as well as increased heat resistance or impermeability to water, performance can be enhanced by impregnating graphite with resins, metals, and oxidation inhibitors. We offer bronze bushing with graphite for extreme service requirements. Our choice of metal will depend on requirements but should provide good corrosion resistance and thermal conductivity.

Bronze Bushing Material

Leaded Commercial Bronze

This alloy family is a free-machining brass with a higher electrical and thermal conductivity than that of standard free-machining brass. C31400 and C31600 both have natural corrosion resistance combined with the machinability typical of leaded brasses as well as good cold workability.

C31400 | C31600

Phospor Bronze

Phosphor bronze is an alloy of copper containing 0.5–11% tin and 0.01-0.35% phosphorus. The tin increases the corrosion resistance and strength of the alloy. The phosphorus increases the wear resistance and stiffness of the alloy. These alloys are notable for their toughness, strength, low coefficient of friction, and fine grain.

Aluminum Bronze

Aluminum bronze is the highest strength standard copper-based alloy. Randall Bearings produces C95400, C95500, AMS 4880-C95510, and C95900 in standard sizes of rounds, tubes, and rectangles. Aluminum in conjunction with iron and nickel in C95500 acts as a strengthener in these alloys. All of the aluminum bronzes can be heat treated, further increasing tensile strength.

Leaded Tin Bronze

The lead content in high-leaded tin bronze alloys is between 7 percent and 15 percent. These alloys are free cutting and retain favorable thermal conductivity and good lubricity due to the lead content. Alloy C93200, also termed bearing bronze, SAE 660, SAE 660 bronze, and SAE 660 bearing bronze, is considered this family’s workhorse alloy and is widely used in many bearing applications.


Manganese Bronze

Manganese bronzes can operate under very high loads and speeds. However, bearing applications require reliable lubrication. Besides excellent mechanical qualities, these alloys have good corrosion resistance. The standard alloy in this group is high tensile C86300, which is comprised of copper, manganese, aluminum, and iron. This combination raises the tensile strength to over 110,000 KSI.
