Cylindrical Bushes with Flange Size Permaglide are precision-engineered components designed to provide smooth, low-friction operation in a variety of applications. The cylindrical shape and flanged design offer stability and easy installation, while the Permaglide material ensures superior wear resistance and durability.

The Permaglide material, which is typically a composite or advanced polymer, is chosen for its exceptional sliding properties and ability to maintain a consistent coefficient of friction over a wide range of temperatures and operating conditions. This material is also known for its resistance to corrosion, wear, and chemical attack, making it suitable for use in harsh environments.

The flanged size of the bushes allows for secure installation and positioning within a housing or assembly. This design feature ensures that the bushes will remain in place and function properly, even under high loads and vibrations.

Cylindrical Bushes with Flange Size Permaglide are commonly used in applications such as linear guides, sliding mechanisms, and precision positioning systems. They are particularly suited for applications where smooth, precise, and reliable movement is critical, such as in robotics, automation equipment, and precision manufacturing.

Overall, Cylindrical Bushes with Flange Size Permaglide offer a combination of precision engineering, superior material properties, and a flanged design that makes them an excellent choice for demanding applications requiring smooth, low-friction operation.

In the case of maintenance-free, Gleitlager with the sliding material E40, lubrication is not necessary at any point during the operating life due to the use of as a dry lubricant.

The low-maintenance, polymer composite plain bearings with the sliding material E50 receive an initial lubrication at the start of operation. Since the sliding layer has lubrication pockets, this initial lubrication is sufficient in most cases.

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:

• JDB Series (Graphite Plugged Bronze): Excellent for high-load, low-speed applications, intermittent motion, and high temperatures. The graphite plugs provide continuous solid lubrication. Ideal for heavy machinery, molds, and hydraulic components.

• 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.
