High Performance Gear Couplings

Return to Products Home

KOP-FLEX® revolutionized the industry in early 1950's by pioneering a high performance gear coupling for Turbomachinery. Although the vast majority of new applications are for high performance disc or diaphragm couplings, gear couplings are still the work horse in hundreds of applications throughout the world. A majority of these installations in gas turbine load and accessory drive applications feature KOP-FLEX (formerly known as Koppers).
The gear coupling, with its continuous oil lubrication method, if properly maintained, has tremendous torque capacity in a given diameter compared to non-lubricated type high performance couplings.
