Yayin da igiyar ruwa ke matsawa zuwa tsayinsa mai ƙarfi, jigon sine-wave yana faɗuwa, yana haifar da ɗan ƙara girma a cikin diamita na waje ($ D_{out}$). Wannan fadada radial $\ Delta D$ na iya kusanta ta $\Delta D = \ frac{0.02 f (D_{out} + D_{in})}{N_w^2}$, inda $f$ shine juyowa. A cikin ƙananan juzu'i, rashin yin la'akari da wannan fadada na iya haifar da ɗaure ko tsangwama tare da bangon gidaje, wanda ke gabatar da rikice-rikice na parasitic kuma ya canza yanayin bazara. Madaidaicin ƙira a cikin na'urorin likitanci ta amfani da Bakin Karfe 316 yana buƙatar diamita ta zama aƙalla $D_{out} + \Delta D + \ rubutu{clearance}$ don kula da madaidaicin jujjuyawar lodi da hana lalacewa akan gidaje.
