The fasteners have been installed in more than 7,000 new RINGFEDER shaft-hub connections around the world.
“BUMAX was the only company that could provide the high-strength fasteners with the corrosion resistance we required for our applications,” said Rainer Peter, senior product manager for Shaft-Hub Connections at RINGFEDER POWER TRANSMISSION.
The German-based company primarily uses BUMAX 109 and BUMAX DX (Duplex) 129 screws to provide the necessary strength and corrosion-resistance for its demanding applications. BUMAX fasteners are also used in all of the stainless-steel RINGFEDER products, which are manufactured at the company’s production plants in Germany and the Czech Republic.
RINGFEDER POWER TRANSMISSION is a long-standing customer of BUMAX that has used high-strength, corrosion-resistant BUMAX stainless-steel screws since 2012, since they’re able to transmit high torques with the company’s rust-proof locking devices.
In 2020, the company installed over 80,000 BUMAX screws in over 7,000 locking devices.
“The unique advantage of BUMAX 109 is its high strength, which means that we achieve the same transmission values with our rust-proof shrink discs as our standard shrink discs with screws of quality 10.9,” added Peter.
