Steel base inlaid graphite bearings are specifically designed for high-temperature applications in winder and crane support systems. These bearings incorporate graphite inserts within a steel base, providing exceptional wear resistance and lubrication properties in demanding environments.

Graphite, known for its low coefficient of friction and high thermal stability, serves as the primary lubricating material within the bearing. This natural lubricant effectively reduces friction and wear, ensuring smooth and reliable operation of the winder or crane support system.

The steel base of these bearings offers excellent strength and durability, making them suitable for applications involving heavy loads and high temperatures. The steel construction ensures that the bearings can withstand the rigors of continuous operation and maintain their integrity over extended periods.

In winder and crane support systems, where precise alignment and stability are crucial, steel base inlaid graphite bearings offer a superior solution. They provide the necessary support and stability, while also ensuring smooth and reliable motion of the equipment.

The high-temperature resistance of these bearings makes them ideal for applications involving extreme operating conditions. Wh it's a winder operating in a hot environment or a crane supporting heavy loads in a demanding industrial setting, steel base inlaid graphite bearings can handle the challenge.

In summary, steel base inlaid graphite bearings are an excellent choice for high-temperature applications in winder and crane support systems. Their combination of graphite's lubricating properties and steel's strength and durability ensures smooth and reliable operation in demanding environments.

Bearing characteristics

Modern design is creating a huge demand for today's self-lubricating bearing materials.Even in severe extreme operating conditions and maximum load conditions maintenance is required.With the increasing of cost requirement, the reliability of equipment and plant operation is becoming more and more demanding.

Metal self - lubricating bearings are maintenance-free and self - lubricating under long - term service conditions, making it possible to design reliable long - term self - lubricating systems.Metal type self-lubricating bearing materials can be widely used in high load and low speed conditions of rotation, swing and linear reciprocating movement, but also suitable for traditional lubrication can not be reached or is prohibited from use, or in special conditions such as dust, impact load or radiation conditions need long-term and stable use.

Precautions for use

1.Use standard specifications when possible;

2.Please pay attention to the presence of foreign bodies on the surface during assembly.

3.After using the sliding surface, the surface is black or gray-black due to the oil film formed by the solid lubricant. Please do not scrub and use as usual.

4.Before assembly, if the lubricating oil is applied to the grinding parts, the short running period can be reduced, which is conducive to the mechanical operation and operation.

5.When assembling, press in slowly, and do not knock, so as to avoid damaging the bearing and causing deformation.

6.When designing, different parts should be made of appropriate materials, so as to improve the mechanical properties and prolong the service life of the bearings.

7.In high load and reciprocating motion, screw fixation is recommended.

8.Stainless steel or chrome plating is recommended for grinding shafts in fresh water, sea water and at sea.

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.
