FLENDER Standard Couplings Torsionally Rigid All-Steel Couplings — ARPEX ARS-6 Series © Siemens AG 2015 General information ■ Overview Coupling suitable for use in potentially explosive atmospheres. ■ Benefits 6 ARPEX couplings of the ARS-6 series are outstanding for their versatility. Most standard components are available from stock, resulting in short delivery times. Their use in potentially explosive atmospheres in accordance with the current ATEX Directive is possible. ■ Application ARPEX couplings of the ARS-6 series are a versatile coupling solution which thanks to standard modular components can be used for most drive requirements at a low to medium speed.
Torques of between 170 and 106000 Nm can be transmitted at a permitted angular misalignment of 0.7°. The open flange form is regarded as very easy to fit and has easily accessible screw connection points. On most types, the intermediate spacer can be radially fitted without moving the connected units. Main areas of application for the ARS-6 series: • Paper-making machines • Printing machines • Compressors • Pumps • Fans and blowers • Film and foil machines • Generators • Presses • Metalworking machines • Conveyors • Crane systems • Textile machines • Plastics processing machines • Centrifuges 6/4 Siemens MD 10.1 · 2015
