GGB Develops Bearings for Hydropower Applications
Thorofare, N.J., February 17, 2005 -- GGB, formerly Glacier Garlock Bearings, now offers two self-lubricating, fiber/resin composite bearing materials, HPF and HPM, to meet the demands of hydropower applications such as Francis, Kaplan and Pelton turbines, as well as gates and valves.
Both HPF and HPM combine the self-lubricating properties of PTFE with the high strength and stability of an oriented glass-fiber-filled epoxy resin backing. The maintenance-free materials provide high load capacities, low wear rate and friction, long service life, low water absorption for dimensional stability and excellent corrosion resistance.
HPF consists of a proprietary filled PTFE liner bonded to a fiberglass reinforced composite backing. It is available in both flat and cylindrical geometries.
HPM consists of a bearing liner composed of PTFE and high-strength fiber winding encapsulated in an epoxy resin enhanced with self-lubricating filler. It is available only in cylindrical form.
