Bushing Flanged Size Metal-Polymer Bearings, in metric sizes, refers to a specific type of bushing that features a flange design and is manufactured to metric dimensions. Metal-Polymer Bearings, often associated with sealing products, here could indicate a specific manufacturer or a generic term for a bushing that meets certain quality standards or specifications.

In this context, the bushing is a mechanical component designed to reduce friction and wear between two moving parts. The flanged design provides additional stability and support, ensuring a secure fit and preventing axial movement.

Metric sizes for these bushings refer to the dimensions of the bushing and its flange, measured in millimeters (mm) or other metric units. These dimensions may include the outer diameter (OD), inner diameter (ID), flange diameter, and flange thickness, among others.

When selecting a Bushing Flanged Size Metal-Polymer Bearings in metric sizes, it's important to consider the specific requirements of the application, including the dimensions of the mating parts, the operating environment, and the desired performance characteristics. Manufacturers typically provide detailed specifications and product catalogs to help customers choose the right bushing for their needs.

In summary, Bushing Flanged Size Metal-Polymer Bearings, in metric sizes, refers to a high-quality bushing with a flange design and metric dimensions, suitable for applications requiring reduced friction, wear resistance, and stable fitting.

Suitable for dry running, low coefficient of friction, lower wear, good sliding characteristics, the transfer film created can protect the mating metal surfaces, suitable for rotating and oscillating movement, high chemical resistance, low absorption of water and swelling. The VSV-40 improved the friction and much good wear resistance over the common CSB-10 range under lubricated operation.

Structure

1. /Polymer fibers mixture thickness 0.01~0.03mm. The lead-free bearing layer provides an excellent initial transfer film, which effectively coats the mating surfaces of the bearing assembly, forming an oxide type solid lubricant film.
2. Sintered bronze powder thickness 0.20-0.35mm, provides max. thermal conductivity away from the bearing surface also serves as a reservoir for the mixture.
3. Steel backing, provides high load carrying capacity, excellent heat dissipation.
4. Copper/Tin plating thickness 0.002mm provides good corrosion resistance.

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.

• SF Series (PTFE-Based Composite): Typically metal-backed (SF-1: steel, SF-2: steel/bronze) with a PTFE-based lining. Offers very low friction, good wear resistance, and suitability for dry running or marginal lubrication. Common in automotive, office equipment, and hydraulics.

• 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.
