Brass Bushing Used In Everywhere
Brass Bushing Used In Propeller Shaft Bushings
The propeller shaft of a boat goes through the hull and attaches to the propeller. Brass sleeve bushings are often used for propeller shafts. Because brass bushings do not rust, they are an ideal metal for use in the marine environment. Some marine bushings are made of two parts. They have a housing made of steel, and an inner bushing made of brass pressed onto the shaft. The reason for this is that steel is stronger than brass, and the steel housing can withstand pressure. The inner shell made of brass will bear the rotation of the shaft. These bushings are called brass-backed composite bearings.
Water Pump Brass Sleeve Bushing
There is a water pump in a water-cooled car engine, and there is a brass bushing in the main shaft of the pump. It is because the brass bushing has anti-rust properties and also has anti-friction properties when it is in contact with steel. A rubber seal is placed on the inner part of the sleeve to prevent water leakage. This seal allows a trace amount of fluid to penetrate to lubricate the bushing. Manufacturers never recommend using only straight water. Instead, they recommend using fluids such as antifreeze, which have built-in lubricants to help combat friction between the bushing and the pump shaft.
Electric Motors – Brass Parts
Many electric motors use brass bushings on both sides of the armature (rotating part) to support the motor shaft. There are many reasons for using brass sleeve bushings. First, it is cheap and plentiful. Second, it has anti-friction properties, so only a small amount of grease is needed. Third, it is easy to manufacture with common machine tools.
Slide Brass Bearings
Many times, a machine shaft does not rotate, but rather slides in and out of an assembly. Desktop printers use this motion in carrying the print head back and forth on the paper. If you have a printer, look at the sliding carriage that carries the ink cartridge. The carriage is mounted on polished steel shafts. Many times, the carriage slide bushings are made out of brass.

BRASS SLEEVE BUSHING
Brass Sleeve Bushing Design
Brass is a very useful alloy. Made out of melted copper and zinc, it becomes harder than any of the base metals, and it holds its shape well while remaining workable. When it comes in contact with steel machine shafts, it will not bind to steel because it is a dissimilar metal. Because of these attributes, brass bushing makes an ideal part for bearings.
Top quality
In instances where constant lubrication is paramount, bronze sleeve bearings are the go-to product, these will sometimes utilize lubricant plugs (PTFE or graphite) to assist with any lubrication problems.
- Low Friction Coefficient
- Durability and Longevity
- Easy Installation and Maintenance

What Is Brass Bushing?
Brass is a metal alloy primarily composed of copper and zinc. However, other metals—such as iron, aluminum, silicon, and manganese—are also mixed in to produce different properties and color variations. For instance, a high zinc content leads to increased strength and ductility, while the inclusion of manganese results in enhanced corrosion resistance.
Using brass bushings, you will find they last long enough. Most brass bushings are made from 360 brass, with a Rockwell hardness of B78.
Some of the common types of brass sleeve bushing available include:
Red brass(C23000 brass)
Yellow brass
330 brass
360 brass
464 brass
Properties of Brass
Compared to bronze, brass is more malleable, making it ideal for applications that require a high level of formability. On the other hand, it also demonstrates a significantly lower melting point (900 degrees Celsius).

The Differences Between Bronze and Brass Bushing
The differences in material compositions between bronze and brass bushing result in varying characteristics that make them suitable for different use cases. For instance, bronze’s higher level of resistance to saltwater corrosion makes it a better choice for ship components than brass, while brass’s exceptional workability and machinability make it more suitable for tubing and pole applications.
Bronze | Brass |
Harder, more brittle | Greater malleability |
Melting point of 950 degrees Celsius | Melting point of 900 degrees Celsius |
Excellent corrosion resistance (incl. saltwater) | Good corrosion resistance |
Suitable for some decorative applications (e.g., sculptures, musical instruments, etc.) | More suited for decorative applications (due to gold color) |
Plug Graphite Brass Sleeve Bushing
Plug graphite brass sleeve bushings are primarily used in applications that need continual lubrication in hard-to-reach areas. machined out of continuous cast bronze and plugged with graphite plugs. A film of lubricant is transferred to the shaft as it begins to turn. These bearings offer continuous self-lubricating without maintenance.


Phosphor Bronze, Brass, And Aluminum Bronze Material
- Phosphor bronze, also known as QSn10-1 and QSn6.5-0.1, is a copper alloy distinguished by its exceptional strength, corrosion resistance, and unique bronze color. The addition of phosphorus enhances these properties, making it ideal for a wide range of applications.
- Brass is a versatile copper alloy that comes in various compositions, including H62, H65, H68, H70, H85, and H90, each with distinct characteristics. Brass alloys are primarily made by adding zinc to copper, resulting in a wide spectrum of properties. Brass is appreciated for its malleability, corrosion resistance, and attractive golden appearance. H62 brass, for instance, is often used in plumbing fittings, while H85 and H90 brass are favored for their excellent strength and electrical conductivity, making them suitable for electrical components.
- Aluminum bronze alloys, such as CuAL9Ni3Fe2, CuAL10Ni5Fe4, and CuAL11Ni6Fe6, are remarkable for their exceptional corrosion resistance and high-strength properties. These alloys are created by adding aluminum to copper, along with small amounts of nickel and iron. Aluminum bronze is widely used in marine environments, where its resistance to saltwater corrosion is invaluable. It is also employed in heavy machinery components, such as gears and bearings, due to its robustness and wear resistance.
Types of Brass Sleeve Bushings
There are several types of brass sleeve bushings available, each designed to meet specific requirements.
Flanged Brass Bushings
Flanged bushings feature an integrated flange that provides additional support and stability. They are commonly used in applications where axial loads are present, such as in gearboxes or transmission systems.
Straight Brass Bushings
Straight bushings, also known as cylindrical bushings, have a simple cylindrical shape without any flanges. These bushings are suitable for applications with linear motion, such as in sliding doors or drawer slides.
Custom Brass Bushings
For applications with unique requirements, custom brass bushings can be manufactured to meet specific dimensions, tolerances, and material properties.


How To Choose The Right Brass Sleeve Bushing
To select the right brass sleeve bushing for your application, consider the following factors:
- Load and speed requirements: Evaluate the load and speed of your application to determine the appropriate bushing size and type.
- Operating environment: Consider the presence of moisture, corrosive substances, and temperature fluctuations in your application, as this can impact the performance of the bushing.
- Material compatibility: Ensure that the brass sleeve bushing is compatible with the materials it will be in contact with, to avoid galvanic corrosion or other adverse reactions.
- Custom specifications: For unique applications, consult with a bushing manufacturer to develop custom brass bushings tailored to your specific needs.
