DXTSEALS offers a comprehensive range of high-quality metal O-rings to ensure secure and reliable sealing for vacuum, gases, and liquids. Our metal O-rings are engineered to perform exceptionally well, even under extreme conditions. These static and metallic sealing elements can withstand ultrahigh vacuum environments and pressures of up to 5500 bar.
Designed for durability and versatility, DXTSEALS metal O-rings are suitable for a wide temperature range, spanning from -269 degrees Celsius to +750 degrees Celsius. If you need higher temperature applications, please contact our team. Furthermore, our rings exhibit excellent resistance to radioactive radiation, chlorides, corrosion, and other aggressive substances. Our metal O-rings retain superior performance over time and show no signs of aging during usage and storage.
The DXTSEALS spring-energized PTFE seal represents the latest generation of spring-activated Teflon seals. These seals feature a specialized precision jacket/lip crafted from Teflon (or other high-performance polymers) and a corrosion-resistant stainless steel spring.
This unique combination allows the spring to press the seal lips against the gland and rod walls, with the pressure further assisting the spring force. The spring adjusts for lip wear, hardware tolerances, and eccentricities, providing continuous resilience to the seal lips. The DXTSEALS design, with its sealing lip and spring arrangement, offers superior leakage protection compared to traditional lip seals.

Rotary Seals For Mining Industry
Floating seals, also known as mechanical face seals or lifetime face seals, are essential components in various mining applications. Mining machinery floating seals provide effective sealing and protection for critical components in harsh and abrasive environments. Here's how mechanical metal face seals are used in different mining applications:
Mining Trucks with Wet Braking Systems
Mining truck floating seal komatsu are used in the wheel hubs of mining trucks to protect the bearings and other components from contaminants like dust, water, and debris. Metal face seals for haul trucks ensure the longevity and reliability of wheel hub assemblies, which are essential for the safe operation of mining trucks. Floating seals designed for wet braking systems also plays a crucial role in preventing water ingress and maintaining brake efficiency.
Steering Drive Axle and Final Drives
Floating seals are used in steering drive axles and final drives to seal the connection between the axle and wheel hub. They prevent the entry of abrasive materials and water, extending the life of these critical components and reducing maintenance requirements.
Mining Scraper Chain Conveyor
Floating seals are employed in the conveyor's chain wheel hubs to prevent abrasive materials and contaminants from damaging the bearings and seals. They ensure the smooth and efficient operation of the scraper chain conveyor, which is used to transport bulk materials in mining applications.
Underground Mining Trucks
In underground mining, where conditions are particularly challenging, floating seals are used in various components of mining trucks, such as wheel hubs and final drives. They help protect vital parts from abrasive particles, extending the service life of the equipment.
Coal Winning Machine
Floating seals are used in coal winning machines, such as continuous miners or longwall shearers, to seal critical components like cutting heads and gearboxes. These seals prevent coal dust and debris from entering the machinery, reducing wear and tear and ensuring efficient coal extraction.
Boom-Type Road Header
Boom-type road headers are used in mining for tunnel excavation and underground development. Floating seals can be found in the drive systems of road headers, helping to seal gearboxes and protect them from abrasive materials present in the mining environment.
In all of these mining applications, floating seals are crucial for minimizing downtime, reducing maintenance costs, and ensuring the safety and efficiency of mining equipment. They help extend the service life of critical components and contribute to the overall productivity of mining operations.
Axle Floating Seal Final Drive
Floating seals, also known as final drive face seal replacement or duo-cone seals, are commonly used in axle applications, including steering drive axles and final drives in various types of heavy machinery and vehicles. They play a crucial role in ensuring the integrity and performance of these critical components. Here's how floating seals are applied in axle systems:
Steering Drive Axle
Steering floating seal final drive axles are found in heavy-duty vehicles and equipment such as trucks, buses, and construction machinery.
Wheel Hubs: final drive seal are often used in the wheel hubs of steering drive axles to seal against contaminants and maintain the integrity of the axle assembly.
These seals prevent the entry of dirt, dust, water, and abrasive materials into the wheel bearings and other critical components.
By maintaining a proper seal, floating seals help extend the service life of the wheel hub assembly, reduce maintenance requirements, and ensure reliable steering and driving performance.
Final Drives
Final drives are an integral part of heavy machinery and are used in various applications, including excavators, bulldozers, and mining equipment.
Final Drive Housings: Floating seals are commonly employed in the final drive housings of these machines to seal against contaminants and maintain lubrication.
They prevent abrasive materials, dirt, and water from entering the final drive assembly, protecting critical components such as gears and bearings.
Proper sealing in the final drives contributes to the overall durability and performance of the heavy machinery.
Reduced maintenance and extended service intervals result from effective sealing, enhancing the machinery's productivity.
In steering drive axles and final drives, floating seals are essential for preventing premature wear, reducing the risk of costly breakdowns, and ensuring the reliable operation of heavy machinery and vehicles. These seals contribute to safety, efficiency, and cost-effectiveness in various industrial and construction applications.
