Self-lubricating guide solid lubrication wear-resisting plate precision mold standard parts

The guide part is an indispensable and important component in the die. Its function is to determine and maintain the relative position between the upper and lower die or other parts of relative motion is accurate, and to maintain the motion steering accuracy. The self-lubricating guide refers to the guide parts with good self-lubrication and friction after special process treatment, which can also be called oil-bearing guide parts. It is mainly used in large and medium size, fine and long life molds with high guidance accuracy.

Features of self-lubricating guide:

The self-lubricating guide parts produced by Jiaxing Gurun are filled with special solid lubricants such as graphite, MoS2 and on the metal matrix working surface to make it have a certain bearing capacity and good self-lubricating and wear resistance. The main characteristics are as follows:

In the case of no oil, can maintain self-lubrication, so it can simplify the mold structure, reduce oil consumption, avoid oil pollution damage, purify the working environment.

Simple structure, convenient installation, can reduce the cost, reduce tooling manufacturing and maintenance costs.

Because it has good self-lubrication and wear resistance, even in bad working conditions, can also completely avoid the occurrence of "overburning" or "bite card" phenomenon

CAST BRONZE BEARINGS

1) Casting (castability)

Refers to the properties of metal materials that can be cast to obtain qualified castings. Foundability mainly includes fluidity, shrinkage and segregation. Fluidity is the ability of a liquid metal to fill a mold. Shrinkage refers to the degree of volume shrinkage when the casting solidifies; Segregation refers to the inhomogeneity of the internal chemical composition and structure of the metal due to the difference in the sequence of crystallization during the cooling and solidification of the metal.

(2) malleability

Refers to the performance of metal materials that can change shape without cracking during pressure working. It includes in the liquid or cold state can be cast and forged, rolling, stretching, extrusion and other processing, the quality of the malleability is mainly related to the chemical composition of metal materials.

(3) Machinability (Machinability, Machinability)

Refers to the degree of difficulty that a metal material becomes a qualified workpiece after being machined by a tool. Cutting machinability is often used to measure the surface roughness of the workpiece after processing, allowable cutting speed and the degree of tool wear, it is related to the chemical composition of metal materials, mechanical properties, thermal conductivity and work hardening degree and many other factors, usually with hardness and toughness for cutting machinability is roughly broken. Generally speaking, the higher the hardness of metal materials, the more difficult to cut; Although the hardness is not high, but toughness, cutting is very difficult.

(4) weldability (weldability)

Refers to the adaptability of metal materials to welding processing. It mainly refers to the difficulty of obtaining high-quality welded joints under certain welding process conditions. It includes two aspects: one is the bonding performance, that is, under certain welding process conditions, a certain metal forming welding defect sensitivity; The second is the use of performance, that is, under certain welding process conditions. Applicability of certain metal welded joints to service requirements.

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.
