Euroflex
As part of the Rexnord Coupling portfolio, high-performance Rexnord Euroflex Disc Couplings are uniquely designed and manufactured for each and every application they encounter in the energy industry. Whether for a gas turbine driving a power generator on an offshore drilling platform, a steam turbine driving a centrifugal gas compressor in a refinery, or a motor driving a boiler feedwater pump in a thermal power plant, customers can trust their Rexnord Euroflex Disc Couplings have been optimized to ensure reliable operation for the lifetime of the drive train when connecting their critical rotating equipment.
Unlike a traditional engineered to order (ETO) disc coupling selected from standard sizes, each Rexnord Euroflex Disc, Coupling is custom designed and individually produced through a highly efficient, industry-leading engineering and manufacturing process. The result is a true engineered and optimized coupling. The advantage to the customer is they receive a high-performance coupling that is competitive in design with traditional coupling suppliers, and provides an economical solution. By adhering to strict guidelines that specify the components of the coupling, including hardware and disc packs, each Rexnord Euroflex Disc Coupling is customized to fit each customer’s application. Our coupling designs are not constrained by a fixed bolt circle diameter or a set number of bolts. This allows Rexnord to truly optimize the coupling for the application.
