With finished bore. » » OD1 Without finished bore. OD2 Without finished bore. 250mm, 300mm Imperial (inches): 3.5" (88.9mm), » Hubs are designed with threaded pull-off holes. Special lengths available upon request. 5" (127mm), 2) » Shaft distance S Metric (mm): 100mm, 140mm, » Spacer sleeves (type NEN) designed as electrical cable sleeves are API compliant. » 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 andE- / H-spacers are given on pages 20 to 22. » E-spacers in preferred lengths up to size 343-6 are available from stock. 7" (177.8mm), » The total lengths and the weights apply to the whole coupling of type NEN with maximum bores D1/D2 and the preferred shaft distance S=V.
