Split Bronze Bushing, also known as a split bush or sleeve bearing, is a type of mechanical component designed to reduce friction and wear in rotating or sliding applications. It is made from CuSn8 rolled phosphor bronze, a high-performance material that exhibits excellent wear resistance, corrosion resistance, and mechanical strength.

CuSn8, a phosphor bronze alloy, is composed primarily of copper with the addition of tin and phosphorus. The rolling process used to form this alloy enhances its mechanical properties, such as tensile strength and ductility, making it suitable for precision applications. The phosphor content in the alloy also contributes to its wear resistance, allowing it to maintain its performance over extended periods of use.

Split Bronze Bushings are designed with a split or segmented construction, which allows them to be easily installed around a shaft or rod without the need for disassembly of the entire assembly. This feature simplifies the installation process and reduces downtime. Once installed, the bushings provide a smooth, low-friction surface for the rotating or sliding components, improving efficiency and extending the service life of the equipment.

Due to their exceptional performance characteristics, Split Bronze Bushings made from CuSn8 rolled phosphor bronze are widely used in various industries, including automotive, machinery, and electrical equipment. They are particularly suitable for high-load and high-speed applications where durability and reliability are critical.

In summary, Split Bronze Bushings made from CuSn8 rolled phosphor bronze are an effective solution for reducing friction and wear in rotating or sliding applications. Their split construction simplifies installation, while their high-performance material ensures excellent performance and durability.

The lead bronze with 10 ~ 30% lead added in tin bronze is the tile sheath copper, the copper and tin in the metal form a hard matrix, while the lead is distributed among the bronze tissues. This copper lead alloy has the highest thermal conductivity, and the temperature is lower than that of other bearing alloys during friction, so it can be used on the bearing bush of mild steel.

The hardness of the earthen alloy is higher, wrapped bronze plain bronze bearings are often used as the material of the axle of the train wheel, airplane and automobile.This alloy can also be used in the bearing bush of some transmission machines, such as pulley, gear shaft, etc. Wrapped bronze plain bronze bearings are also widely used in the high speed internal combustion engine

White alloy (also known as t alloy, black gold, hardware) color gray and white.There are usually two kinds: crime and lead.

(1) tin white alloy: tin content of 80%, and a small amount of antimony and copper.Tin for soft matrix, curium and copper or tin and antimony are combined into a hard crystal crystal spread on the matrix, good wear resistance, can withstand a large load, toughness and corrosion resistance are also very good.

Because of more tin, the price is more expensive, generally suitable for steam turbines, generators, large aircraft, automobiles, internal combustion engines, as well as high pressure and high speed of special heavy machinery bearing.

(2) lead-based white alloy: it contains about 70% lead and is composed of other components such as antimony and tin.Among them: lead and lead tin crystals constitute the maternal soft substrate, and antimony and tin becomes hard antimonide tin's software, for this kind of white metal containing lead more, price is low, and suitable for casting, but toughness is low, and can't bear heavy load, so many applications in small mechanical bearing shell, for example: the general fan, water pump, oil pump, ball mill, motor, etc.

Wrapped bronze plain bearings application field

Used for lifting machinery, construction machinery, automobile tractor chassis, machine tool industry and mining machinery, can also be made into bearing bush, flanged bushing, thrust gasket and ball bowl and other forms.

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.
