Benefits » N-ARPEX couplings of the ARN-6/-8/-10 series are outstanding for their application-optimized construction. » API 610 &API 671 compliance on request. » A special catching device acts to secure the intermediate spacer in the event of plate breakage. » ATEX compliance on request. Application » N-ARPEX couplings of the ARN-6/-8/-10 series are used wherever reliable torque transmission is called for, even in cases of often unavoidable shaft misalignment. They are universally applicable over a temperature range of from -50°C (or even as low as -60°C on request) up to +280°C, are torsionally rigid, free of torsional backlash and enable quiet running at a constant angular velocity. They are wear- free and maintenance-free and, if correctly fitted, can be expected to have an unlimited service life. Plate-PackDesigns » The plate packs of the N-ARPEX ARN series are designed with hexagon, octagon and decagon plates, depending on the coupling size. The number of screw connections is indicated in the denomination of the ARN-6/-8/-10 series. Hexagon plates have 6 bolting points, octagon plates have 8 bolting points and decagon plates have 10 bolting points. The hexagon plates, octagon plates and decagon plates up to size 631 are designed as ring plates. Sizes 694 to 988 are designed as segmented plates.
