FLENDER Standard Couplings Torsionally Rigid All-Steel Couplings — ARPEX ARS-6 Series © Siemens AG 2015 Type NZN ■ Selection and ordering data Torsionally rigid coupling type NZN with variable shaft distance S and reinforced intermediate spacer. Type NZN with radially freely dismountable intermediate spacer. NL1 S1 LZ S NL2 G_MD10_XX_00148a SZ Ш DA Ш ND1 Ш D1 Ш DZ Ш ND2 Ш D2 6 N Z N The permitted length of the intermediate spacer depends on the maximum operating speed of the coupling (see following table). Weights and mass moments of inertia apply to the entire coupling with maximum bores D1/D2 and S = 1000 mm.
In the case of individual order of the intermediate spacer, the length (LZ) must be specified. 6/16 Siemens MD 10.1 · 2015 Size Rated torque Maximum speed Dimensions in mm Mass moment of inertia Article No. Weight Shaft distance Order codes for bore diameters and tolerances are specified in catalog section 3 DA TKN nKmax D1/D2 ND1/ND2 DZ SZ NL1/NL2 S1 LZ S J m Keyway DIN 6885 min. min. mm Nm rpm max.
