Bronze CuSn12 Cast Bronze Bushings without Oil Groove …

CuSn12 cast bronze bushings without an oil groove are mechanical components made from a specific bronze alloy known as CuSn12. This alloy is composed of approximately 88% copper and 12% tin, giving it excellent corrosion resistance, high wear resistance, and superior strength.

These bushings are essentially simple cylindrical or sleeve-like parts that are fitted between two components of a machine to reduce friction and wear. They are often used in applications that require high load-bearing capacity and where extreme conditions like high temperatures or corrosive environments may be present.

The term “cast” in “cast bronze bushings” refers to the manufacturing process used to produce these components. In this process, the CuSn12 alloy is melted and then poured into a mold in the shape of the desired bushing. Once the molten metal has cooled and solidified, the bushing is removed from the mold and is then ready for use.

The phrase “without an oil groove” indicates that these bushings do not have grooves or channels that are often designed into the surface of some types of bushings to distribute lubricating oil more evenly. In some applications, these grooves are not necessary, either due to the type of motion (such as oscillating rather than continuous rotation), the use of self-lubricating materials, or the design of the surrounding components.

CuSn12 cast bronze bushings without an oil groove are specialized mechanical components that are valued for their robustness and versatility in a variety of demanding applications.

CuSn12 Tin Bronze Bushes with M2, milling

CuSn12 is a tin bronze alloy composed of approximately 88% copper and 12% tin. It is widely known for its high strength, good wear resistance, and excellent corrosion resistance.

Tin Bronze Bushes made from CuSn12 are commonly used in mechanical systems to reduce friction between moving parts and provide support for rotational or linear movement. They are suitable for high-stress applications due to their excellent material properties.

When these bushes are described as having an “M2 milling” and an “M2 thread,” it means they have been processed through a specific machining operation.

“Milling” is a machining process where a rotating cutting tool (the mill) removes material from the workpiece to create a desired shape. In this case, the M2 specification could possibly refer to the size of the milling cutter used, but without more specific context, it’s hard to be certain.

“M2 thread” refers to the thread size created on or in the bushing. The M designation refers to a metric thread, and the number following it (in this case, 2) represents the nominal diameter of the thread in millimeters. Therefore, an M2 thread has a nominal diameter of 2mm.

The term “machining finished parts” refers to the fact that these CuSn12 tin bronze bushes have been completely processed and are ready for use in their intended application. This could involve various machining operations like turning, milling, drilling, or threading to meet precise dimensional and surface finish specifications.

To sum up, CuSn12 tin bronze bushes with M2 milling, M2 thread, and machining finished parts are high-strength, wear-resistant components that have been meticulously processed to precise specifications and are ready for installation and use in a range of demanding mechanical systems.

Milling bronze bushings is a machining process that involves the use of a rotary cutting tool (the mill) to remove material from the bronze workpiece and shape it into the desired form. This could be a part of the manufacturing process of bushings, where raw material (bronze in this case) is transformed into a finished part.

Here are some key aspects related to milling bronze bushings:

  1. Material Selection: Bronze alloys are chosen for bushings due to their excellent resistance to wear and corrosion, good load-carrying capability, and suitability for both low and high-temperature environments.
  2. Milling Process: Milling is a versatile process that can produce a wide range of shapes and features, such as slots, pockets, and threads. It’s an important operation for creating the complex geometries often required in bushings.
  3. Equipment: The milling process for bronze bushings is carried out using a milling machine. This could be a traditional manually operated machine or a CNC (Computer Numerical Control) mill that provides high precision and automation.
  4. Tooling: Milling bronze requires the selection of appropriate cutting tools, which must be chosen with consideration to the material properties of bronze. Carbide tools are often used due to their hardness and durability.
  5. Finishing: After milling, additional surface finishing processes may be required, such as polishing or coating, to improve the surface quality or enhance the bushing’s resistance to wear and corrosion.
  6. Quality Control: After the milling process, the bushings will be inspected to ensure they meet the desired dimensions and surface quality. This may involve measurements with calipers, micrometers, or more advanced metrology equipment.

Milling bronze bushings is a critical operation in the manufacturing process of these components, requiring careful selection of material, appropriate machining equipment, the right cutting tools, and strict quality control procedures.

Hydraulic lift cylinder bronze bearing parts

A hydraulic lift cylinder consists of several key components, including the piston. The piston, often made of bronze in certain types of cylinders, plays an essential role in the functioning of the system. Here is some more detail on the various parts and their functions:

Piston: The piston is a disc or short cylinder that fits tightly within the cylinder tube. In a hydraulic lift cylinder, the piston’s movement is used to generate force. The hydraulic fluid acts on the piston surface, which moves under the fluid pressure. If the piston is made of bronze, it’s because bronze has good load-bearing capacity, resistance to wear and corrosion, and it offers excellent sliding properties, which are all important attributes for this function.

Cylinder Barrel: The cylinder barrel is typically a seamless tube within which the piston moves back and forth. It houses the pressure and the piston. The inside surface is finished to a precise size and finish to provide a sealing surface for the piston.

Cylinder Base or Cap: The base (bottom) and cap (top) of the cylinder are usually bolted or threaded to the cylinder barrel. The base may have a hydraulic fluid port.

Cylinder Head: This is attached to the end of the cylinder barrel that has the piston rod extending out of the cylinder. The head contains a bearing for the piston rod and seals to prevent the leakage of hydraulic fluid.

Piston Rod: The piston rod extends from the piston to the outside of the cylinder tube. The rod moves back and forth as the piston is actuated. The outer end of the rod can be attached to the load that is being moved.

Seals: Seals are used to prevent the leakage of hydraulic fluid between the piston and the cylinder barrel and also at the head where the piston rod exits the cylinder.

Ports: Ports are the inlets/outlets of the cylinder where the hydraulic fluid enters or leaves. The position and control of the fluid through the ports determine the movement of the piston.

Understanding these parts and their functions can help in troubleshooting hydraulic lift cylinders or when designing systems that utilize these components. The choice of materials, such as bronze for the piston, will often depend on the specific demands of the system such as load, speed, pressure, and environmental conditions.
