When it comes to bushings and bearings for heavy-duty applications, extra large size bronze graphite plugged bushings with flange dimensions are a popular choice. These bushings are designed to provide superior strength, durability, and wear resistance, making them ideal for applications that require high load capacity and long-lasting performance.

The bronze material used in these bushings offers excellent mechanical properties, including high strength and hardness. This ensures that the bushings can withstand heavy loads and impacts, reducing the risk of damage or failure. Additionally, the graphite plug provides excellent lubrication, reducing friction and wear between the rotating components and the bushing itself.

The flange dimensions of these bushings are designed to fit into specific equipment and machinery. The flange provides a stable mounting base, ensuring that the bushing remains securely in place during operation. The flange also helps to distribute the load evenly across the bushing, further enhancing its durability and performance.

Extra large size bronze graphite plugged bushings with flange dimensions are commonly used in a variety of applications, including mining, construction, and heavy machinery. They are particularly suited for applications where high loads, speeds, and temperatures are present, as they can maintain their performance under such conditions.

In summary, extra large size bronze graphite plugged bushings with flange dimensions offer superior strength, durability, and wear resistance for heavy-duty applications. Their precision engineering and flange design ensure reliable performance and long-lasting service life.

There are three different types of flanged bronze bushings, including plain bushings, oil or grease grooved flanged bushings, and graphite plugged bushings. We manufacture all three types at Atlas Bronze for use in a variety of industrial applications, but today we’re going to take a closer look at bronzegleitlager.com.

High-Temperature Dry-Running Sleeve Bearings Embedded
Graphite is a dry form of lubrication that reduces friction between two metal surfaces. This form of lubrication can withstand higher temperatures than liquid or oil based lubricants. Graphiting is accomplished by grooving the ID face of the bearing and then pressing graphite into the cavities under extremely high pressure. Graphite is often used in bearing lubrication for hard to reach places that cannot be lubricated manually.

Graphite provides a layer of dry lubrication that operates in high-temperature environments.

bronze bearings are porous and embedded with graphite for continuous lubrication.

Note: Dynamic load capacity is the maximum load a bearing can with stand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

What Are Graphite Plugged Bronze Bushings?

Graphite plugged bushings are a special type of bushing that is used in applications that need continuous lubrication, but don’t offer easy access for the lubrication to be added manually on a regular basis. This type of bushing is made with graphite impregnated into the small holes in the bushing’s surface. When in use, these bushings release the graphite, creating a film of lubricant to keep machinery running smoothly.

Why Use Graphite Plugged Bronze Bushings

Graphite plugged bushings are beneficial anytime an application needs ongoing lubrication, but also needs to perform for long periods without maintenance. These bearings are self-lubricating, so additional oil and grease is not needed.

Because graphite plugged bearings self-lubricate, money is saved on maintenance and replacement—both in materials and in labor costs. Additionally, less downtime is needed to add more lubricant or perform other everyday maintenance tasks. Graphite plugged bushings have better wear resistance than other types of bearings. This is because when graphite plugged bushings are in use, there is very minimal friction thanks to the lubricant film they produce. Friction is what wears parts down and causes them to need eventual replacement, so limiting this is the key to durability.

Not only do graphite plugged bushings stand up to a great deal of wear and heavy use, they’re also resistant to corrosion when in damp, humid, or marine environments. In industries where bearings will be exposed to caustic chemicals, graphite plugged bushings from Atlas Bronze are an ideal choice for their chemical resistance.

Another benefit of choosing this type of bushing is that they can be safely used in extreme hot and cold temperatures, indoors and out, and still perform well.

Beyond Grease: A Deep Dive into Oilless Bushings & Why Viiplus Leads the Way

Friction is the enemy of efficiency. In countless machines, from massive industrial equipment to intricate automotive components, the constant battle against wear and tear dictates performance, longevity, and maintenance costs. Traditionally, grease and oil have been the go-to solutions, but they come with their own set of challenges: frequent re-lubrication, potential contamination, environmental concerns, and limitations in extreme conditions.

Enter the world of oilless bushings, also known as self-lubricating bearings or sliding bearings. These innovative components offer a smarter way to manage friction, delivering reliable movement without the need for external lubrication.

At Viiplus (www.viiplus.com), we don't just supply these components; we engineer solutions. Leveraging deep expertise in metallurgy and tribology (the science of friction, wear, and lubrication), we've become a leading name in sliding bearing technology. But what exactly are oilless bushings, and why should they be on your radar? Let's dive deeper.

What Exactly Are Oilless Bushings? The Science of Self-Lubrication

Unlike traditional ball or roller bearings that rely on rolling elements and require constant lubrication films, oilless bushings operate on the principle of sliding motion. Their "magic" lies in their material composition and structure, designed to provide their own lubrication at the bearing surface. This can be achieved through several key technologies:

1. Solid Lubricants Embedded: Materials like graphite, MoS₂, or PTFE are embedded directly into the metallic matrix (often bronze) of the bushing. As the shaft rotates or slides, a minuscule amount of this solid lubricant is transferred to the mating surface, creating a low-friction film.

2. Porous Metal Structures: Sintered bronze or iron materials are created with microscopic pores. These pores are vacuum-impregnated with oil during manufacturing. In operation, slight heating causes the oil to expand and seep onto the bearing surface, providing lubrication. When it cools, the capillary action draws the oil back in, creating a closed-loop system.

3. Layered Composites: These often feature a strong backing (like steel), an intermediate sintered layer (like bronze), and a low-friction overlay (often PTFE-based). The PTFE layer provides the primary sliding surface, offering extremely low friction.

Contrasting Logic: Oilless vs. Traditionally Lubricated Bearings

The Tangible Benefits: Why Make the Switch?

Choosing oilless bushings isn't just about eliminating grease guns. It's about unlocking significant operational advantages:

• Drastically Reduced Maintenance: This is the most obvious benefit. No re-greasing means less labor, less scheduled downtime, and simplified maintenance protocols. Imagine the savings across a factory floor!

• Enhanced Reliability: Lubricant starvation is a major cause of bearing failure. Self-lubricating bearings ensure consistent lubrication, leading to predictable performance and longer service life, especially in hard-to-reach locations.

• Superior Performance in Harsh Conditions: Oilless bushings excel where traditional lubricants fail:

  • High Temperatures: Certain types can operate at temperatures far exceeding the limits of conventional greases.

  • Low Temperatures: No grease means no stiffening or freezing issues.

  • Contaminated Environments: The absence of sticky grease reduces the ingress of dirt, dust, and debris.

  • Vacuum or Underwater: Ideal for applications where liquid lubricants are impractical or impossible.

  •  
  •  
  •  

• Cost Savings (Total Cost of Ownership): While the initial purchase price might sometimes be higher, the TCO is often significantly lower due to savings on lubricants, labor, downtime, and potential component failure replacement.

• Environmental Friendliness: Eliminating oil and grease leakage prevents contamination of products, machinery, and the environment. Crucial for industries like food processing, pharmaceuticals, and textiles.

• Compact & Simplified Designs: Without the need for lubrication systems (nipples, lines, reservoirs), machine designs can be more compact and streamlined.
