鋼(gang)制拖鏈的(de)(de)寬度(du)(du)，拉伸長度(du)(du)，壓縮長度(du)(du)，兩端的(de)(de)連(lian)接方(fang)(fang)(fang)法等，能(neng)夠(gou)任意組(zu)合(he)的(de)(de)產(chan)品系列，其原材料、外形(xing)、加(jia)工處理方(fang)(fang)(fang)法及尺寸大(da)小都能(neng)夠(gou)依(yi)據實際情況而定，鋼(gang)制拖鏈的(de)(de)一(yi)(yi)個根本組(zu)成部分是在(zai)每個折頁里(li)都裝有一(yi)(yi)個起(qi)(qi)支(zhi)撐(cheng)穩定作用的(de)(de)骨(gu)架(jia)(jia)，此(ci)骨(gu)架(jia)(jia)能(neng)夠(gou)經過(guo)不同(tong)的(de)(de)加(jia)工方(fang)(fang)(fang)法與外部折頁材料緊密相連(lian)，在(zai)一(yi)(yi)定的(de)(de)溫度(du)(du)下，憑借(jie)特別(bie)助熔劑就能(neng)夠(gou)使內部的(de)(de)PVC骨(gu)架(jia)(jia)與外部的(de)(de)折頁牢固(gu)地(di)粘接在(zai)一(yi)(yi)起(qi)(qi)。若護罩(zhao)是在(zai)中等溫度(du)(du)環(huan)境(jing)下使用，就能(neng)夠(gou)選用此(ci)種方(fang)(fang)(fang)法，此(ci)種熱(re)粘接護罩(zhao)徹底(di)不必對(dui)其進行(xing)保養，且防水、防塵、耐油、耐酸(suan)。
鋼制(zhi)(zhi)拖(tuo)鏈經過改善鏈節之(zhi)間(jian)的受(shou)力，使(shi)(shi)拖(tuo)鏈在超(chao)寬的的情況下可保持(chi)穩定運行(xing)，由(you)于(yu)拖(tuo)鏈在加(jia)工(gong)時采用(yong)(yong)了(le)冷切割，避免了(le)冷沖壓加(jia)工(gong)發生(sheng)的材料變(bian)型(xing)，使(shi)(shi)銷軸(zhou)與鏈板的接(jie)觸面更加(jia)滑(hua)潤(run)，使(shi)(shi)拖(tuo)鏈在超(chao)長行(xing)程(cheng)下可不(bu)(bu)必支撐。使(shi)(shi)電纜或橡(xiang)膠(jiao)管與拖(tuo)鏈之(zhi)間(jian)不(bu)(bu)發生(sheng)相對運動，不(bu)(bu)發生(sheng)歪曲(qu)變(bian)形(xing)(xing)，鋼制(zhi)(zhi)拖(tuo)鏈經鍍鉻處理外(wai)形(xing)(xing)效果新穎，結構合(he)理，靈活強(qiang)度(du)高，鋼性好不(bu)(bu)變(bian)形(xing)(xing)，安裝(zhuang)(zhuang)方便，使(shi)(shi)用(yong)(yong)牢(lao)靠(kao)，易(yi)拆裝(zhuang)(zhuang)，尤其是本產品采用(yong)(yong)了(le)高強(qiang)度(du)耐(nai)磨(mo)(mo)材料，合(he)金銅為軸(zhou)銷，提(ti)高了(le)產品的耐(nai)磨(mo)(mo)強(qiang)度(du)，曲(qu)折更靈活，阻力更小，降低了(le)噪音，然后可保證長期使(shi)(shi)用(yong)(yong)不(bu)(bu)變(bian)形(xing)(xing)，不(bu)(bu)下垂。
