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.
The more common types of brass sleeve bushing are:
Flanged brass sleeve bushing: designed for axial and side loads.
Cylindrical bearing: for radial loads, and for higher side loads, a combination of both a thrust washer and a cylindrical bearing is often used.
Sleeve bearings are commonly made from bronze, steel, or stainless steel, while brass and plastic sleeve bearings are also manufactured for specific applications.
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.

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.
