CuZn25Al6Fe3Mn4, also known as C86300, is a type of graphite bronze alloy that is commonly used as a material for bushing slider washers and other sliding components. This alloy offers a unique combination of properties that make it suitable for a wide range of applications.
The addition of graphite particles in CuZn25Al6Fe3Mn4 bronze provides excellent self-lubricating properties. Graphite is a natural lubricant that reduces friction and wear between sliding surfaces. This allows the bushing slider washers made from this alloy to operate smoothly and efficiently, even under high loads and speeds.
In addition to its self-lubricating properties, CuZn25Al6Fe3Mn4 bronze also possesses high strength and good corrosion resistance. The alloy's copper-zinc base provides good ductility and toughness, while the addition of aluminum, iron, and manganese improves its mechanical properties and corrosion resistance. This makes the alloy suitable for use in harsh environments and demanding applications.
CuZn25Al6Fe3Mn4 bronze bushing slider washers are often used in mechanical systems that require smooth and reliable sliding motion. They are commonly found in automotive transmissions, industrial machinery, and other applications where precise alignment and smooth operation are critical.
The alloy's machinability is also a key advantage, as it can be easily cut and shaped to meet specific application requirements. This allows manufacturers to produce precision-fitted bushing slider washers that ensure optimal performance and reliability.
In summary, CuZn25Al6Fe3Mn4 C86300 graphite bronze is an excellent material choice for bushing slider washers and other sliding components. Its self-lubricating properties, high strength, good corrosion resistance, and machinability make it suitable for a wide range of applications where smooth and reliable sliding motion is essential.

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.

Exploring Viiplus's Portfolio: Finding Your Solution

Viiplus offers a comprehensive range of self-lubricating bearings designed to meet diverse application needs. Understanding the different series helps in selection:

• JF Series (Bimetal Bushings): Combines a steel backing with a sintered bronze or lead-bronze lining. Good load capacity and fatigue strength. Often used with grease or oil but can operate marginally lubricated. Found in engines, chassis parts, and agricultural machinery.

• FB Series (Wrapped Bronze): Often made from bronze strip, sometimes with lubrication pockets or through-holes. A cost-effective solution for medium loads and speeds, typically requiring initial greasing but offering extended re-lubrication intervals.
