The Self-Lubricating Gasket and Washer: An Innovation for Industrial Applications
The current industrial landscape sees a proliferation of gaskets and washers used in a myriad of applications. These essential sealing devices, when paired with an appropriate load, can prevent leakage, isolate environments and maintain the integrity of equipment. Unfortunately, over 70% of gasket and washer failures in industrial applications are due to an insufficient load, often the result of light flanges that provide inadequate load force. This issue is particularly acute in oil and water applications, where the lack of leakage doesn’t typically draw significant attention.
Today, thanks to advances in materials science, an innovative solution has emerged: the self-lubricating gasket and washer. This evolution in sealing technology aims to reduce downtime and maintenance while enhancing safety and productivity across multiple industries such as chemical, food, medicine, paper making, mining, valves and metallurgy.
Invention in High Temperature Conditions

The high temperature resistant gasket and metal washer are exceptional examples of this innovation. These devices leverage excellent metal performance and self-lubricating graphite material, offering robust solutions for high-temperature work conditions.
Moreover, a range of composite washers, including PTFE, POM, and Bronze washers, cater to different structural forms. For instance, the PTFE gasket series, renowned for its excellent performance, features a flat surface structure manufactured from red and black PTFE. On the other hand, the POM gasket series presents a protruding surface structure made from yellow, black or blue materials, resulting in highly integrated and optimized washer properties.Thrust washer bearings are made from self-lubricating composite bushing materials that promote maintenance-free, dry operation for a wide range of …high performance self-lubricating bearings … plain bearings—particularly high load available in bearings, thrust washers, and strip.
Maintenance-Free Operation， Reduced Friction and Wear
The inclusion of self-lubricating features significantly reduces friction, a critical advantage in various industrial applications. Lower friction means less heat generation and decreased wear and tear, thereby extending the operational lifespan of the bearing. Reduced friction also contributes to improved energy efficiency and smoothness of operation. Another notable advantage of self-lubricating metric thrust washers is their maintenance-free operation. Since they don’t require periodic lubrication, the maintenance cost and downtime are significantly reduced. This aspect makes them ideal for applications where regular maintenance is challenging or impossible.
Wear Resistance for Gearboxes, Compressors and Pumps

In demanding applications such as gearboxes, compressors, and pumps, self-lubricating gaskets become crucial. Traditional materials, like wear-resistant PTFE gaskets or POM gaskets, are often selected. However, these are susceptible to corrosion and wear, especially under high temperatures. In such situations, stainless steel matrix fabric gaskets can offer high wear and corrosion resistance, even under high temperatures and when certification requirements are stringent.
Advantages in Power, Chemical and Nuclear Industries
Self-lubricating gaskets bring substantial benefits to various industries. They are not limited to specific equipment (bonnet, manhole, mirror) and can operate in oil and water conditions. This new class of sealing solutions aids customers in managing and resolving leakage issues.
Furthermore, metal-polymer self-lubricating bearings, designed for corrosive chemical environments, are another innovative addition. With good lubricated operation and excellent greased operation, they offer broad compliance with RoHS standards and are available in standard sizes. These stainless steel-backed washers are customizable and can be obtained by stamping, with lubricant holes and machined grooves, offering unique design possibilities.
Stainless steel 316-based gaskets and washers， Versatility in Application
Stainless steel 316-based gaskets and washers, capable of self-lubrication, are highly wear-resistant and temperature resistant. They far outperform traditional metal gaskets and can withstand temperature variations from -195℃ to +280℃.
For applications requiring high cleanliness, such as drinking water, composite gaskets and washers that comply with RoHS standards are also available. These bearings are highly versatile, finding applications in a broad array of industries, including automotive, aerospace, heavy machinery, and more. Their ability to operate effectively in harsh environments and extreme temperatures enhances their appeal across these diverse applications.
Self-lubricating gaskets and washers
Self-lubricating gaskets and washers represent a significant step forward in sealing technology, promising extended service life and fewer failures due to insufficient load. By mitigating common industrial challenges, they hold the potential to revolutionize the field of industrial sealing solutions.
Self-lubricating metric thrust washers in bearings present an innovative approach to mitigating the challenges of traditional, conventionally lubricated bearings. By offering high load capacity, dimensional rigidity, reduced friction, and maintenance-free operation, these bearings deliver reliability, extended service life, and operational efficiency.
