Polygon Company - POLYLUBE® High Temperature Bushings

|
|
POLYLUBE® HT bushing is a high load, low RPM bushing designed for applications where self-lubrication is desired, but conventional composite bushing will not perform due to high temperatures. This product has been designed to provide excellent performance at elevated temperatures. With a glass transition temperature of over 450°F this epoxy filament wound structure exhibits superb performance over extended exposure to elevated temperatures. The bushing material is focused on applications where the bushing will be exposed to temperatures up to 450°F.
In addition to its high compressive properties (in both static and dynamic modes), this bushing material is inherently self-lubricating. The self-lubrication capability of Polygon Company's new material means that the use of expensive high temperature external lubricants are no longer necessary.
Properties
The POLYLUBE® HT bushing is a high strength, self-lubricating material that offers performance enhancements over greased systems, as well as graphite loaded bronze structures, some iron-copper graphites, polysulfone, PEEK®, and polyimide bushing materials.
Applications
PolyLube High Temperature applications are not just for elevated temperature environments but also for applications where the bearing may need to resist thermal expansion during operation. One example of this is in snowmobile clutch markets. In these applications, the clutch speed goes from 0 to very high RPM's in micro-seconds (and vice versa). During this cycling, friction is rising because speed is being dramatically increased. As the friction goes up so does the temperature of the associated components. A high temperature composite bearing material can resist these expansion phenomena and as a result offer better long term wear, improved bearing durability, and less seizure opportunity than conventional metal bearing materials.
