HiSpin ® HS40 and HiSpin ® The PDR RT seal is designed specifically for high speeds and is compatible with cutting-edge solutions in modern rotorcraft or helicopters.
What are the characteristics and advantages of these seals? Let's take a look together.
HiSpin ® PDR RT
HiSpin ® The PDR RT seal ensures necessary lubrication while also preventing leakage at high speeds, thereby optimizing the performance of the rotorcraft gearbox.
HiSpin ® The unique design of the PDR RT sealing lip ensures effective lubrication on one side of the seal while keeping the rotating shaft on the other side dry. The sealing element can withstand extremely high speeds at high temperatures, with minimal friction and power loss, and can maintain lubrication in the gearbox while keeping the rotating shaft dry.
HiSpin ® The excellent high-speed sealing ability of PDR RT not only meets the demand for high-speed rotary seals in helicopter transmissions, but also extends the service life of transmission components, thereby extending the service life of helicopters and ultimately helping to improve safety.
Features and advantages
The surface speed that can be processed will be greater than 60 meters/second
Bidirectional sealing capacity
Compact design reduces the requirement for assembly space
Temperature range: -60 ℃ to+200 ℃
Ability to withstand pressure
Excellent sealing performance (with or without lubrication)

HiSpin ® HS40 has excellent low friction performance and is designed for the harsh conditions of high-speed electric aerospace applications such as electric hoists and electromechanical actuators.
HiSpin ® HS40 has unique hydrodynamic characteristics that help reduce frictional torque. Meanwhile, returning oil can improve sealing performance without damaging the rotating shaft.
This seal is made from the patented material XLT high-performance fluoroelastomer (FKM) series from Treburg. It provides excellent performance against harsh engine conditions such as high motor speeds and corrosive synthetic liquids. The testing of the new generation XLT composites has proven that these low-temperature FKM level performance is excellent and extends the temperature performance of traditional FKM elastomers.
Features and advantages
Running speed up to 40 meters/second
Bidirectional sealing capacity
Compact design reduces the requirement for assembly space
XLT FKM has a wider temperature range: -45 ℃ to+200 ℃
Ability to handle fuel depletion
Excellent sealing performance in different lubrication environments
Excellent low friction torque
Reduce fever
Excellent compatibility with various electric transmission devices and other corrosive liquids
Negligible shaft wear
Easy installation
A cost-effective solution
Provide different outer diameter configurations, such as partial encapsulation
Improving efficiency, improving safety, and extending service life are the development directions of the rotorcraft industry. In addition, the increasing speed also requires the sealing integrity to reach 100%. With over 60 years of experience and continuous innovation capabilities, Treburg is fully prepared to meet the current and future needs of the industry.
