Cast Bronze Bushing – Bronze turned bearing bushing

Cast bronze bushings are made by pouring molten bronze into precisely shaped molds. After cooling and solidifying, the bushing is removed and finished with trimming, grinding, and polishing to meet exact specifications.

Tin bronze bushings, composed of specific copper and tin ratios, are valued for their excellent wear resistance and strong bearing properties, achieved through the casting process.

The bronze alloy is cast using continuous or centrifugal methods, which improve the metal’s grain structure and mechanical properties. This results in cast bronze bushings with exceptional structural integrity, durability, compression resistance, and the ability to maintain strength at high temperatures, making them ideal for demanding applications where wear resistance is critical.

C93200, also known as SAE 660, is a high-leaded tin bronze alloy renowned for its mechanical strength, machinability, and resistance to wear and corrosion. It typically consists of 81–85% copper, 6.3–7.5% tin, 6–8% lead, 1–4% zinc, 1% nickel, and trace amounts of antimony and iron.

Cast bronze and tin bronze bushings are used in a wide range of applications, including heavy machinery, hydraulic systems, power transmission devices, automotive components, bearings, cylinders, gears, sprockets, impellers, pumps, valves, and washers. They are essential for the reliable operation of equipment across various industries.

A bronze turned bearing bushing minimizes friction and wear between moving parts in mechanical systems, serving as an interface that allows smooth rotation. Bronze is preferred for bushings due to its excellent anti-friction properties. The term “turned” refers to the manufacturing process of shaping bronze stock on a lathe to achieve precise dimensions.

These bushings are commonly found in automotive and industrial machinery, as well as any systems requiring smooth and reliable movement. Using bronze bushings can extend a system’s lifespan by reducing part wear.

Furthermore, bronze bushings can handle heavy and shock loads, perform well under harsh conditions, and resist corrosion, making them ideal for applications where durability and reliability are essential.

cast bronze bearings is based on high-strength brass or other material based on your choice, lubricating by oil added in the oil grooves. This typecast bronze sleeve bushing has the same performance as other bearings. but with much higher hardness, twice lifetime for low-speed application compared with tin bronze bushing. It’s also called cast bearing, brass bush, cooper bearing, solid sliding bearing, oil grooves plain bearing, cast bronze bearing, cast bronze, and so on.

• High-Strength Brasses

The high-strength brasses (sometimes improperly referred to as manganese bronzes) are modifications of the familiar 60% Cu40% Zn yellow brass known as Muntz Metal. Alloy C86300 contains manganese, aluminum, and iron, which raise its tensile strength to well over 800 MPa (115 ksi). Alloy C86400 is somewhat lower in strength, but it contains one percent lead to improve its machinability. Despite their high tensile strength, the alloys’ fatigue resistance can only be rated as moderate. These high-tensile brasses can operate under very high loads and at moderately high speeds; however, they require hardened, well-aligned shafts and reliable lubrication. Being relatively hard, they have little capacity to embed trapped particles and therefore do not tolerate dirty lubricants.

• Aluminum Bronzes

Aluminum bronzes are the highest-strength standard copper-based bearing alloys. Aluminum is a potent strengthener in these alloys; in general, the higher the alloys’ aluminum content, the higher their strength. Alloys with aluminum contents higher than about 9.5% can be heat treated, and this is noted in the designation “HT” following the alloys’ UNS numbers. Alloy C95500HT, for example, can attain tensile strengths in excess of 800 MPa (115 ksi). One interesting feature of aluminum bronzes is their high
elevated temperature strength. The compressive strength of C95400 at 260 C (500 F) is the same as that of tin bronzes at room temperature. The aluminum bronzes have the highest fatigue strength of all
bronze bearing materials, and they can resist repeated and severe impact loads very well. One important disadvantage is their relatively poor machinability. They can be turned, bored, and reamed,
but like the tin bronzes, they are difficult to broach. Like the high tensile brasses, most of the aluminum bronzes must be used against steel shafts hardened to greater than 500 HB. Alloy C95200 is somewhat more forgiving in this respect. As a class, aluminum bronzes require reliable full-film lubrication to prevent metal-to-metal contact and possible scoring. Both bearing and shaft should be machined to surface finishes finer than 0.4-0.5 µm (15-20 µinch) rms. The alloys do not embed dirt well, and generally, 20 require good shaft alignment. Their thermal conductivity is only slightly lower than some of the lower strength alloys, and as a result, they can be used at moderate speeds if shaft hardness, shaft
alignment, and lubrication are all well controlled.

• C93200 Bronzes

Alloy C93200 (SAE Alloy 660) is generally considered to be the workhorse alloy of this series. Originally developed as a low-tin composition during World War II, the alloy remains in wide use
today. Major areas of application include light to moderate duty general purpose bearings.

Available bronze bushings with internal oil grooves and oil holes.

A bronze bushing with inner grooves and an oil hole is a type of mechanical component designed to provide smooth and low-friction movement between two parts in a machine or system. It is typically used in applications where there is a need for relative motion, such as in gears, pulleys, and linkages. The inner grooves and oil hole work together to improve lubrication and extend the life of the bushing.

Here’s a brief description of the features and functions of a bronze bushing with inner grooves and an oil hole:

1. Material: Bronze bushings are made from a copper alloy, typically consisting of copper and tin, which provides excellent wear resistance and corrosion resistance. This makes them ideal for use in demanding environments where other materials might fail or corrode.
2. Inner Grooves: The inner grooves are designed to distribute the lubrication evenly across the entire surface of the bushing, allowing for smooth and consistent movement between the bushing and the shaft or other components it is in contact with. These grooves also help to retain lubricant, which reduces the need for frequent re-lubrication and extends the service life of the bushing.
3. Oil Hole: The oil hole is a small opening on the outer surface of the bushing that allows for the introduction of lubricant into the grooves. This ensures that the lubricant can effectively reach the contact surfaces between the bushing and the mating components, reducing friction and wear.
4. Applications: Bronze bushings with inner grooves and an oil hole can be found in a variety of industrial and automotive applications, including pumps, motors, gearboxes, and transmissions. They are particularly suitable for applications where high loads, vibrations, or oscillatory motion are present.
5. Maintenance: While bronze bushings are generally low-maintenance components, it is important to keep them adequately lubricated to ensure optimal performance and longevity. Regular inspection and lubrication through the oil hole can help prevent premature wear and failure.

A bronze bushing with inner grooves and an oil hole is a durable, efficient component that offers excellent wear and corrosion resistance and low friction in various applications. Proper lubrication is essential for its longevity and reliable performance.

Bushings are extensively used in industries such as injection molding, automotive, engineering machinery, hydraulics, large gearboxes, metallurgical casting, train support systems, mining machinery, marine vessels, turbines, cranes, and food machinery turbine bearings.
