Following over 20 years of extensive use by U.S. and European navies in ships, submarines, hovercraft, and hydrofoils, Karon® self-lubricated bearings are now available for hydropower applications. With unequaled load capacity, low friction, and greatly extended service life, these bearings offer a significant upgrade in performance while eliminating periodic lubrication and maintenance.
KAron, a polyester, thermosetting resin-based material, incorporating PTFE particles, was originally developed for the very demanding load and environmental requirements of military and commercial aircraft. It was later adapted for a wide variety of submerged or near-water marine applications.
In hydropower, KAron is ideally suited for wicket gate bearings, control linkage systems, operating rings, valve pivots, gate wear bars, fish screen bushings, and chain linkage. The high bearing pressure of KAron makes it ideal for highly loaded kaplan hub bushings and spherical bearings. Kamatics has supplied a number of sites with KAron bearings of this type. KAron has excellent dry operating characteristics, thus eliminating "break-in" greases. Being machinable, it is ideal for final on-site sizing.
Kamatics offers KAron with metal or composite backing for new installations or refurbishments in bushing, spherical bearing and wear bar/plate configurations.
