Product Description
The Fiber-Lube HT bearing is a high load, low RPM bearing designed for applications where self-lubrication is desired, but conventional composite bearings will not perform at high temperatures. This product has been designed to provide excellent performance at elevated temperatures. With a glass transition temperature of over 450ºF this epoxy filament wound structure exhibits superb performance over extended exposure to elevated temperatures.
In addition to its high compressive properties (in both static and dynamic modes), this bearing material is inherently self-lubricating. The self-lubrication capability of our new material means that the use of expensive high temperature external lubricants such as polyurea grease, lithium grease, some bentone greases, as well as advanced ester based oils and complex thickening systems may no longer be necessary. The Fiber-Lube HT bearing creates a high strength, self-lubricating journal bearing material that can offer performance enhancements over greased systems, as well as graphite impregnated bronze bushings, some iron-copper graphites, polysulfone, PEEK, and polymide bearing materials.
Fiber-Lube 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 market. In these applications, the clutch speed goes from 0 to very high RPMs 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.
