Polygon is proud to announce recent product and process expansion has enabled production of large composite bearings approaching 30 inches (762 MM) in outside diameter and up to 72 inches in length.
The composite self-lubricating bearing industry has focused primarily on sizes between .500” ID and 6”. While a few attempts have been initiated to broaden that product window, Polygon has decided to make larger bearing sizes a primary focus.
This opens up many new large bore composite bearing applications such as fluid actuation, valves, heavy cranes and even off-shore rig bearings. These fields can now enjoy the benefits known in the aerial lift platform, construction and agricultural equipment markets.
For many years large bearing applications have been dominated by bronze or other metallic constituents requiring significant secondary machining and fabrication to incorporate grease or lubrication paths. These lubrication methods are high maintenance and prone to failure.
"Large bearings are often used in complex machinery where maintenance access is difficult at best. Even with access, downtime is a significant expense. Polylube's lifetime permanent lubrication decreases maintenance and removes one element from the failure equation, lowering total cost of operation.", said James Shobert, Polygon's CEO.
Polygon’s self-lubricated bearings are the new ultimate choice where high loads and corrosive environments present significant engineering challenges. Work boats, naval vessels, wind generation and even oil rigs now have a superior alternative for their demanding large bore applications.
Polygon’s focus is entirely on composites, which enables us to maintain our position as the world’s largest composite bearing supplier. Polygon first designed, developed and patented the composite self-lubricated bearing incorporating DuPont™ Teflon® super-filaments, not a coating or secondary process. Teflon super filaments are integrated into the composite structure eliminating the need for any lubrication.
