Bumax supplies more than 80,000 fasteners to Ringfeder Power Transmission

Swedish manufacturer of stainless steel fasteners Bumax has received orders for more than 80,000 screws from German drive and damping technology manufacturer Ringfeder Power Transmission in the past year.

The company’s locking devices are used as standard in gearboxes and pumps and other machines around the world. The products are used by pharmaceutical companies, the food and beverage industry, in geothermal and hydropower power plants, ship drives and packaging machines.

The fasteners have been installed in more than 7,000 new Ringfeder shaft-hub connections around the world. The company is a long-standing customer of Bumax. It has used Bumax stainless steel screws since 2012 as they are able to transmit high torques with the company’s locking devices.

“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 manufacturer primarily uses Bumax 109 and Bumax DX (Duplex) 129 screws to provide the necessary strength and corrosion resistance.

“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,” concludes Peter.

In 2016, Ringfeder also began using Bumax DX 129 screws for some of its products. Bumax DX 129 offers around 20% higher strength than Bumax 109 and a very high level of corrosion protection.
