Wrapped bronze perforated bearings, Split Bronze Bushing Widely Used for Mining Machinery.

bronze bushings wrapped rolled bushings are made of forged CuSn8 material and despite their thin-walled structure, they withstand very high loads. Therefore, these bronze bushings are for bronze swinging bushings (oscillating movement), the most common use for rolled bushings.

The excellent tin bronze material provides the bushings with excellent sliding properties and high wear resistance.

rolled bushings are used, on the one hand, in standardised dimensions with lubrication pockets. The advantage of this type of bushing is that it can be shortened to any desired length.

We also offer special designs and sizes according to your specifications.

wrapped bronze bushings – Material description

A tin bronze with excellent sliding properties. The material is particularly suitable when high wear resistance, corrosion resistance and fatigue strength are required.

Due to the thin-walled construction of rolled bushings, they can absorb very high specific forces. These may be higher than for the relatively thick-walled turned bushings. Very high loads are possible, especially with swing bronze Bushingss (oscillating motion).

Bushings with lubrication indents ST can easily be replaced by slide bearings with hole pattern LD. Advantages:  Significantly larger grease depot compared to bushings with grooves or lubrication indents  Extension of the running time and the relubrication interval compared to ST bushings  Collection of dirt and wear particles in the lubrication holes

Advantages:

• fully recyclable
• cheaper than machined bronze Bushingss
• minimal space requirement
• weight reduction compared with machined bronze Bushingss or rolling bronze Bushingss
• high load capacity, therefore particularly suitable for swing bronze Bushingss
• grooves are stamped
• grease deposits for long-term lubrication possible

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.
