Any required (mm) » E-spacers in preferred lengths up to size 343-6 are available from stock. » The total lengths, the spacer lenghts and the weights apply to the whole coupling of type MCECMwith maximum bores D1/D2 and the preferred shaft distance S = V. » Hubs are designed with threaded pull-off holes. Special lengths available upon request. Notes » Plate packs in the CEC/CHC intermediate unit assembled at the factory. » In cases with large shaft distances S the intermediate spacer can be designed as an H-spacer. The tube diameters here may slightly diverge. More precise coupling data in cases of variable shaft distances and E- / H-spacers are given on pages 20 to 22 of this catalogue.
