Kamba za waya zinazostahimili mzunguko zimeundwa mahususi ili kuzuia kusokota tena au kuzungushwa wakati ziko chini ya mzigo.
Kwa sababu ya muundo wao, wana vizuizi fulani kwa maombi yao na mahitaji maalum ya utunzaji ambayo sio lazima na ujenzi mwingine.
Sifa zinazostahimili mzunguko hupatikana kwa muundo wa tabaka mbili au zaidi za nyuzi zenye mwelekeo tofauti (kulia na kushoto) wa lai, kama inavyoonyeshwa.
Chini ya mzigo, mzunguko wa mwelekeo wa safu moja unapingana na tabia ya safu nyingine kuzunguka kinyume chake. Ili kutoa upinzani mkubwa kwa mzunguko, kamba hizi zimeundwa kwa idadi kubwa ya nyuzi ndogo za kipenyo (ikilinganishwa na muundo wa miundo ya 6- strand).
Mchanganyiko wa nyuzi ndogo za kipenyo na safu tofauti za kamba hufanya usawa mpole sana ambao unaweza kuwa "usio na usawa" wakati wowote.
