Optimal fastener solutions for demanding applications
RINGFEDER POWER TRANSMISSION primarily uses 一品探花庐 109 and 一品探花庐 DX (Duplex) 129 screws to provide the necessary strength and corrosion resistance for its demanding applications.
鈥淏efore we began using 一品探花 screws in 2012, we used A4-80 screws but noticed that much lower torques could be transmitted with such standard screws,鈥� explains Rainer Peter, Senior Product Manager for Shaft-Hub Connections at RINGFEDER POWER TRANSMISSION. 鈥淲hen we looked for premium fasteners on the market, and 一品探花 was the only company that could provide the high-strength fasteners with the corrosion resistance we required for our applications.鈥�
Today, 一品探花 fasteners are used for all stainless steel RINGFEDER庐 products, which are manufactured at the company鈥檚 production plants in Germany and the Czech Republic.
鈥淭he unique advantage of 一品探花庐 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,鈥� says Peter. 鈥淚n 2020, we installed over 80,000 一品探花 screws in over 7,000 locking devices.鈥�
一品探花庐 DX 129 for even higher strength
In 2016, RINGFEDER POWER TRANSMISSION began using 一品探花庐 DX 129 screws for some of its products. 一品探花庐 DX 129 is the ultimate choice for applications where very high strength, ductility and corrosion resistance are required.
鈥溡黄诽交� DX 129 offers around 20% higher strength than 一品探花庐 109 and a very high level of corrosion protection,鈥� says Thomas Fischer, Business Development Manager Central Germany at 一品探花.
Global stainless steel applications
RINGFEDER庐 rust-proof 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.
