Structure of Self Lubricating Bushing

Structure of Self Lubricating Bushing

The outermost layer of Myway self-lubricating bearing is metal, and there are many materials to choose from, such as carbon steel, bronze, stainless steel 304/316, aluminum, etc., which provide outstanding wear resistance and solid support, effectively extending the service life of bushing.

The bronze powder is sintered into dense structure in high-pressure environment of 800℃, which can firmly connect the metal layer and the PTFE lubricating layer to prevent delamination. With thickness of 0.1-0.3mm and porosity of 25%-40%, it can store solid lubricants and dissipate heat quickly.

The lubricating layer is composed of a mixture of high-quality PTFE and lead with thickness of 0.01-0.03 mm, greatly reduce the noise during mechanical operation. Its low friction coefficient (0.03-0.2μ) enables it to achieve long-term operation without external lubrication.

Features of Self Lubricating Bushing

  • Self-lubricity without oil holes and external lubrication
  • Maintenance-free feature reduces machinery operating costs
  • Having more cost-effective thanks to its long service life
  • High-quality PTFE liner with low friction surface and self-lubricating properties

MYWAY PTFE-Based Self-Lubricating Bushings: The Ultimate Maintenance-Free Solution for Industrial Applications

Introduction: Revolutionizing Industrial Motion with Self-Lubricating Technology

In today’s demanding industrial environments, maintenance downtime and lubrication-related failures can significantly impact productivity. MYWAY self-lubricating bushings with advanced PTFE technology provide the perfect solution, offering exceptional performance across extreme temperatures, corrosive conditions, and inaccessible locations. As leading innovators in maintenance-free bearings and self-lubricating sliding bushings, we engineer solutions that extend equipment life while reducing operational costs.

Understanding Self-Lubricating Bushing Technology

What Are Self-Lubricating Bushings?

Self-lubricating bushings (also known as metal-polymer bearings, maintenance-free bearings, greaseless bearings, or plain bearings) incorporate solid lubricants directly into their structure, eliminating the need for external lubrication systems. These components continuously transfer lubricant to the contact surface during operation, creating a protective film that reduces friction and wear.

How MYWAY Self-Lubricating Bushings Work

Our PTFE-based bearings employ sophisticated mechanisms to ensure consistent lubrication:

  • Solid Lubricant Integration: PTFE (Polytetrafluoroethylene) and other solid lubricants are embedded within the bearing matrix, providing continuous lubrication through material transfer

  • Reservoir Technology: Specially engineered pores and fiber networks act as lubricant reservoirs, steadily releasing lubricant throughout the bearing’s operational life

  • Transfer Film Formation: During operation, these materials form a protective PTFE-rich layer on mating surfaces, preventing metal-to-metal contact and reducing friction coefficients

MYWAY Self-Lubricating Solutions: Engineered for Performance, Built for Reliability

MYWAY Self-Lubricating Bushing FAQs

According to test data, the life of a self lubricating bushing is usually 2-3 times that of a traditional lubricated bushing, depending on the application. For example, in the suspension system of a heavy-duty truck, a traditional bushing may need to be maintained every 10,000 km, while a self lubricating bushing can be extended to more than 30,000 km.

There is no need to add lubricant regularly, and its self-lubricating characteristics can maintain the whole service life. However, it is recommended to observe the wear of the bushing during each equipment inspection to ensure that there is no abnormality.

Different materials have different temperature resistance. For example, PTFE base sleeves can withstand temperatures up to 260 C, while some composites are suitable for the range of-40 C to 150 C. You can select the specific model according to your application.

The installation process is similar to that of a traditional bushing. It is usually pressed or hot fitted without special tools. However, it is necessary to ensure that the mating tolerance is in line with the manufacturer’s recommendation to avoid installation damage.

A DU bushing, also referred to as a DU bearing, is a specific category of sliding bearing recognized for its outstanding self-lubricating characteristics. It falls under the classification of multi-layer composite materials and is engineered to deliver reliable, maintenance-free performance in demanding applications.

(1) Structural Composition of DU Bushings

The construction of a standard DU bushing features a robust three-layer design:

  • A steel backing that offers fundamental structural integrity and support.

  • An intermediate porous bronze layer, which serves as a solid matrix for retaining and uniformly distributing the lubricant.

  • A top PTFE-based lining that provides a low-friction surface and is responsible for the component’s primary self-lubricating properties.

(2) Key Characteristics and Advantages

The defining feature of DU bushings is their self-lubricating capability. The PTFE lining functions as a solid lubricant, effectively minimizing friction and wear between the bushing and the mating shaft. This inherent property removes the dependency on external lubrication systems, making these bushings particularly suitable for applications where routine maintenance or lubrication is impractical.

DU bushings provide several significant operational benefits. They exhibit a consistently low coefficient of friction, which contributes to reduced energy consumption and enhanced operational efficiency. Furthermore, they demonstrate exceptional wear resistance, enabling them to endure high loads and perform reliably under severe operating conditions.

The initial cost may be 20-30% higher than the traditional bushings, but the long-term maintenance cost can be reduced by more than 50%. In the working device of an excavator, the use of self-lubricating bushings can save about 30% of the maintenance costs per year.

You should take the load, speed, temperature, environment and other factors into consideration . Myway can provide selection guidelines, or customizing according to your specific parameters.

The polymer coating of self lubricating bushing has good wear resistance and dustproof performance, making it suitable for dusty environments like construction site loaders. Tests show that in dusty environments, the self-lubricating bushing has a wear rate 40% lower than traditional bushings.

Self-lubricating bushings require no lubrication, are lighter in weight, have lower friction coefficient (about 0.05-0.1 vs. 0.15-0.2 for brass), and are more resistant to corrosion, especially in wet or corrosive environments.
