Designers looking for a solution to radial, lateral and shaft misalignment in applications involving food processing, pharmaceutical, agricultural, offshore, outdoor or corrosive environments may turn to Double Loop Couplings with stainless steel hubs. These Double Loop Couplings are produced with a polyurethane element for flexibility in applications requiring the transmission of rotation in small drives that require compensation for radial, lateral and angular shaft misalignment. They are silent running, have good vibration absorption and offer outstanding electrical and thermal insulation. They are provided with medium torsional stiffness and have an impact and vibration dampening effect. There are no moving parts and they are maintenance free.
The polyurethane material offers good resistance to petrol, oil, Benzol, Toluol, aromatic and non-aromatic coal hydrogen, alcohol, Glycol solvents and many other chemicals. The couplings may be used by temperatures from – 30 °C to + 80 °C. The hubs are made of either galvanized steel for DKPS type, stainless steel 1.4305 A2 for DKPSX type or stainless steel 1.4404 specifically for part DKPSY 4848 10/10 which customers are using for outdoor encoder applications. They are provided with two grub screws which conform to DIN 916. There are four different overall lengths: 28 mm, 35mm, 48 mm and 60 mm. Bores can be supplied up to 19 mm in the largest version and even up to 10mm for the smallest coupling. Feather key grooves are also available, as are combinations of different bore diameters.
