Applications of Self-Lubricating Casting Brass Bushings: JDB650

  • What are Cast Bronze Bushings?

    Cast bronze bushings, also known as plain bearings, are designed to reduce friction between two surfaces as they slide against each other. These components are essential in machines and equipment with rotating or sliding shafts, enhancing overall efficiency and longevity while reducing noise and vibration. Cast bronze bushings generally come in two styles:

    Sleeve Bushings: These are cylindrical in shape with straight inside and outside diameters.

    Flanged Bushings: These feature a flange extending radially outward from one end, acting as a thrust face and preventing axial movement.

    As friction-reducing components, bushings must be made from wear-resistant materials with good sliding properties. While various plastics and metals can be used, bronze offers distinct advantages in heavy-load applications. Its moldability and machinability make bronze ideal for various bushing designs.

    The bronze alloy used in cast bronze bushings undergoes continuous or centrifugal casting, resulting in a finer grain structure and improved mechanical properties. The cast bronze bar is then cut and processed into the final bushing using computer numerical control (CNC) lathes or other precision machining methods. Cast bronze bushings are known for their structural strength, durability, and resistance to compressive forces, making them suitable for harsh, high-wear applications. They can also withstand high temperatures without losing their strength.

  • The production process of these bushings begins with the casting of brass. A predefined mold is used to form molten brass into the exact dimensions of the bushing. Because these are precision components, the molds are designed with exact specifications to ensure a high level of accuracy.

    Post-casting, the bushings undergo CNC (Computer Numeric Control) machining. This is a manufacturing process where pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts, ensuring high precision and repeatability.

Whether used in mining machinery, rocker arm assemblies, or injection molding machines, the JDB650 bushing provides a reliable and cost-effective solution.

  • Self-lubricating casting of bronze bushings typically uses an alloy of bronze that is infused with lubricant during the casting process. Here’s how it works:

    • Mold Creation: The first step in the process is creating a mold in the exact shape and size of the desired bushing. This mold is often made from a durable material like steel that can withstand the high temperatures involved in the casting process.
    • Melting the Bronze: The alloy bronze is heated until it reaches its melting point. The specific alloy used can vary depending on the specific needs of the application, with some common options including tin bronze, aluminum bronze, and phosphor bronze.
    • Adding Lubricant: During the melting process, lubricant is added to the molten bronze. This lubricant is often graphite or molybdenum disulfide, which is known for its excellent lubricating properties.
    • Pouring and Cooling: The molten bronze, now infused with lubricant, is poured into the prepared mold. After it is poured, the bronze is allowed to cool and solidify.
    • Removing the Bushing: Once the bushing has hardened, it is carefully removed from the mold.
    • Finishing: The bushing is then finished as necessary. This could involve grinding, polishing, or coating to meet the final specifications.

    The result is a self-lubricating bronze bushing that can reduce friction and wear in a variety of applications, from machinery to automotive components. The embedded lubricant in the bushing means that it does not need to be regularly oiled, reducing maintenance requirements and increasing the lifespan of the bushing.

A bushing, a crucial component in reducing friction between moving parts, can be crafted from various materials, with brass and bronze being two prominent examples. The material choice can greatly impact the success or failure of a project, with both brass and bronze having their unique advantages.

The Varieties and Manufacturing Processes of Bushings

Cast brass bushings and oil-impregnated bronze bushings are notable for their durability and friction-reducing capabilities. However, they are produced through different methods, and understanding these disparities can aid in identifying the appropriate type for your specific requirements.

The advanced technique of continuous casting is employed in the manufacture of bronze alloy, resulting in a finer grain structure and enhanced mechanical properties compared to the traditional turning process. This method also enables more precision in producing the final product.

The cast bronze bushing creation involves the gravity feeding of bronze powder into a die set corresponding to the bushing size needed. Subsequent pressing and bonding through sintering increase the part’s strength while reducing its porosity to roughly 25%. The piece is then vacuum impregnated with oil, rendering it self-lubricating. These traits make the bushing capable of handling more significant load demands than powdered metal products while requiring minimal upkeep.

The Self-Lubricating Perks of Oil Impregnation

Oil-impregnated bronze bushings need little maintenance due to their self-lubricating properties. This feature decreases friction between mating shafts and other system components, eliminating the constant need for lubricant monitoring and replenishment, saving time and resources for maintenance personnel.

The process includes coating the bronze powder surface with a special oil and drying it to prevent evaporation. The oil impregnation also increases the bronze density, reducing the amount of wear and tear.

The resulting bushings have increased durability, greater resistance to shock, corrosion, and wear, reducing the need for part replacements and lowering operating costs. The bushings’ self-lubricating properties also help deter rust and other damaging deposits from accumulating on the bronze alloy. The lubricating oil also provides protection from high temperatures and adverse environments.

Efficiency of Powder Metallurgy

Producing bronze bushings via the powder metallurgy process is one of the most cost-effective and efficient ways. It yields near-net shape parts, requiring little to no machining. This is achieved by combining bronze powder with a binder to create a self-lubricating component with outstanding mechanical properties.

Powder metallurgy involves four main steps: powder preparation, mixing and blending, compacting, and sintering, each having its own dedicated equipment.

The Advantages of Machining Brass

A brass bushing aids the smooth movement of two other parts by minimizing friction. Depending on its intended use, it can be designed in various ways, such as ball, needle, flange, or sleeve bearings.

The ease with which brass can be machined, particularly when CNC machined, is one of its key benefits. Hence, many manufacturers prefer brass for their machining applications.

While hand-filing of phosphor bronze bushes is possible if they are overly tight for the host, it’s a slow process and may damage the host part. A more effective solution involves using a thick collar over a tensile threaded bar extractor bolt, utilizing the nut on this bolt for a slow and even removal of the bushing. It could also be helpful to heat and freeze the host to try and break any bonds before beginning the machining process.

Exploring Oil Groove Bushings: Materials and Applications

Bronze bushings are designed with oil grooves that significantly help in lubricating and diminishing friction between the shaft and the bushing, thereby boosting performance and prolonging the lifespan of machinery.

These grooves facilitate the lubricant’s flow, ensuring its even distribution across the shaft, thereby providing a protective layer to safeguard the shaft from potential damage and reducing the noise and friction between components.

Oil groove bushings are made from various materials, including steel and plastic. The choice of material is dictated by the application requirements. For heavy-duty applications, bronze bushings are highly recommended. This is because bronze is sturdy and durable, capable of withstanding high loads and resisting corrosion. It also exhibits a high bearing capacity, meaning it can support substantial weight. These bushings are not only easy to install and versatile in their application but also cost-effective, as they can decrease maintenance costs and repair expenses.

The Inside Story: Design

The interior surface of these bushings features grooves that offer a path for the lubricant, ensuring its even spread across the bearing’s surface. This design aids in reducing friction and wear, consequently enhancing the lifespan of the equipment and reducing maintenance costs.

Furthermore, these oil grooves contribute to keeping dirt and chips away from the bushing’s ID, decreasing the chances of machine and equipment damage. The bushing can be further protected from debris by opting for an optional wiper end (order style AA, AB, AD, AE, or AH).

ISO 9001:2008 certified custom manufacturers can supply machined bronze bushings with oil and coolant grooves in an array of sizes, styles, diameters, and lengths. Their services also encompass saw-cutting, heat treating, graphite plugging, and precision machining. These bushings find applications in hydraulic and pneumatic cylinder components, heavy equipment, and marine vessels, with engineering, design assistance services, inventory management control, and Kan Ban delivery also available.

The Role of Oil Groove Bushings

The porous bronze material constituting Oil Groove Bushings serves as a reservoir, storing lubricant for release when necessary. This self-lubrication function reduces friction, heat, and wear, extending equipment life. The need for additional grease or lubrication is eliminated, decreasing maintenance costs and the risk of contamination from unclean oils and lubricants.

The grooves carved into a bronze bushing aim to distribute the lubricant uniformly across the bearing surface, helping to minimize the chances of pitting and galling, thus extending the bushing’s lifespan.

The grooves can be cut in various ways to meet an array of operating conditions and lubrication needs. Generally, it’s advisable to remove less metal where possible rather than machining grooves that are too deep or wide. This is because the more surface area lost, the harder it becomes for the lubricant to reach its point of contact with the load.

A Spectrum of Applications

When feasible, graphite bushings should be pre-soaked in oil before use, allowing the oil to wick and meter to the bearing areas during shaft motion, providing additional lubrication during periods of boundary lubrication. The oil is re-absorbed by the graphite when motion ceases, potentially enhancing the load-bearing capacity of a bushing with an oil hole only by up to 2.5 times.

Oil grooves, specifically designed coolant passageways in a bushing’s ID wall, can be seen on almost all types of bushings, including press fit, head press fit, and renewable. Proper orientation during installation is crucial as this type of bushing requires an external feed from a manifold passage to the internal oil grooves.

Used to decrease friction and noise in equipment, these bushings extend the equipment’s lifespan and reduce maintenance costs. They find common usage in hydraulic press stabbing boxes, water pumps, diesel engine wrist pin bushings, and several other applications.

Strategies for Preventing Rust on Self-Lubricating Bearings

Rust formation on self-lubricating bearings can occur due to various environmental factors. This rusting can disrupt the normal functioning of the bearings, recognized to unnecessary setbacks. Consequently, implementing rust prevention measures is a crucial aspect of bearing maintenance.

Initially, to deter the onset of rust on self-lubricating bearings, it’s crucial to conduct surface pre-treatment:

Surface Cleaning:

The choice of suitable cleaning methods is dictated by the surface character of the rust-prone object and the existing conditions. Conventional methods include solvent cleaning, chemical treatment cleaning, and mechanical cleaning.

Surface Drying:

Post-cleaning, the surface can be dried using filtered, dry compressed air, a dryer set at 120-170℃, or wiped down using clean gauze.

Furthermore, the application of anti-rust oil can be carried out through:

Immersion Technique:

Smaller items can be dipped in anti-rust grease, enabling the surface of the self-lubricating bearing to be covered by a layer of anti-rust grease. The thickness of the oil film can be controlled by adjusting the temperature or viscosity of the anti-rust grease.

Brush Coating Technique:

For outdoor building equipment or uniquely shaped products unsuitable for dipping or spraying, care must be taken to avoid accumulation during brushing, and also to prevent any leakage when painting self-lubricating bearings.

Spraying Technique:

For larger products where oiling by immersion is impractical, spraying is commonly used. This is typically done in clean air environments using filtered compressed air at a pressure of about 0.7Mpa.

The spray method is suitable for solvent diluted anti-rust oil or thin-layer anti-rust oil. However, while applying this method to self-lubricating bearings, it’s essential to ensure optimal fire prevention and labor protection measures are in place.

Hot casting of bronze bushings is a manufacturing process typically employed for creating complex or large parts that would be difficult to produce through other means such as machining. Here’s how the process generally works:

  1. Creation of the Mold: A mold of the desired bushing is first created. This mold is often made from high-grade steel and is designed to withstand the high temperatures required for hot casting.
  2. Melting the Bronze: Bronze is then heated until it reaches its melting point. The melting process is carefully controlled to ensure the bronze maintains its desired properties.
  3. Pouring the Bronze: The molten bronze is then poured into the mold. Care is taken to ensure the molten bronze completely fills the mold to create a part with the desired shape and dimensions.
  4. Cooling and Removal: Once the bronze has been poured into the mold, it is left to cool and solidify. After the bushing has hardened, it is removed from the mold.
  5. Finishing: The resulting bushing may then be finished as needed. This can involve processes like grinding, polishing, or coating to create a final product that meets the desired specifications.

Hot casting allows for the creation of bronze bushings with intricate shapes or features that would be difficult to produce through machining. This makes it an ideal process for producing bushings used in a variety of applications, including in automotive components, machinery, and various industrial equipment.

Main products of the hot casting factory produce various metal components. The actual products can vary widely based on the specific operations of the factory, but they may include:

Automotive parts: This may include engine components, gearbox parts, suspension components, and others. These parts are typically made from aluminum or steel.

Machinery components: Hot casting can be used to produce large, complex parts for various types of machinery. This may include parts for construction equipment, agricultural machinery, and more.

Plumbing fixtures: Hot casting is often used to produce brass or bronze fixtures for plumbing systems. This can include things like faucets, valves, and fittings.

Electrical components: Many electrical components, such as connectors and housings, are made through hot casting.

Medical devices: Some medical equipment, including parts for imaging machines and surgical tools, may be made using hot casting.
