NM coupling bestiet út twa hubs en fleksibele ring by steat om te kompensearjen alle soarten shaft misalignments. De fleksibeleringen binne makke fan Nitile rubber (NBR) dy't in hege ynterne dempingskarakteristyk hawwe dy't it mooglik meitsje om te absorbearjen en wjerstân tsjin oalje, smoargens, fet, focht, ozon en in protte gemyske solvents.
