滾(gun)珠絲杠是將(jiang)回(hui)轉運動轉化為直(zhi)線運動，或將(jiang)直(zhi)線運動轉化為回(hui)轉運動的理(li)想的產品。

滾珠絲(si)杠是(shi)工(gong)(gong)具機械(xie)和精(jing)密機械(xie)上最(zui)常使用(yong)的(de)傳動(dong)(dong)元件，其(qi)主要功能是(shi)將(jiang)旋轉(zhuan)運(yun)動(dong)(dong)轉(zhuan)換成線性運(yun)動(dong)(dong)，或將(jiang)扭矩轉(zhuan)換成軸向反復作用(yong)力，同時(shi)兼具高(gao)精(jing)度、可逆性和高(gao)效率的(de)特點。由于具有很小的(de)摩擦阻力，滾珠絲(si)杠被廣(guang)泛(fan)應用(yong)于各種工(gong)(gong)業設(she)備(bei)和精(jing)密儀器。

滾(gun)(gun)珠(zhu)絲(si)杠(gang)由螺(luo)桿、螺(luo)母(mu)、鋼(gang)球(qiu)、預壓片、反(fan)向器、防塵器組成(cheng)。它的功能是(shi)將旋轉運動(dong)(dong)(dong)(dong)(dong)(dong)轉化成(cheng)直線(xian)運動(dong)(dong)(dong)(dong)(dong)(dong)，這是(shi)艾克(ke)姆(mu)螺(luo)桿的進一步延伸和發(fa)展，這項發(fa)展的重要意義就(jiu)是(shi)將軸承從滑動(dong)(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)(dong)作變成(cheng)滾(gun)(gun)動(dong)(dong)(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)(dong)(dong)作。當滾(gun)(gun)珠(zhu)絲(si)杠(gang)作為主動(dong)(dong)(dong)(dong)(dong)(dong)體時，螺(luo)母(mu)就(jiu)會隨絲(si)桿的轉動(dong)(dong)(dong)(dong)(dong)(dong)角度按照對應規格的導程轉化成(cheng)直線(xian)運動(dong)(dong)(dong)(dong)(dong)(dong)，被動(dong)(dong)(dong)(dong)(dong)(dong)工件可(ke)以通過螺(luo)母(mu)座和螺(luo)母(mu)連接，從而實(shi)現對應的直線(xian)運動(dong)(dong)(dong)(dong)(dong)(dong)。

滾(gun)(gun)(gun)珠(zhu)(zhu)(zhu)絲(si)杠(gang)(gang)軸(zhou)(zhou)承(cheng)為(wei)(wei)適(shi)應各種用(yong)途，提供了(le)標(biao)準(zhun)化種類(lei)繁多的(de)產品(pin)。廣泛應用(yong)于機床，滾(gun)(gun)(gun)珠(zhu)(zhu)(zhu)的(de)循(xun)(xun)環(huan)(huan)方式有循(xun)(xun)環(huan)(huan)導管式、循(xun)(xun)環(huan)(huan)器式、端(duan)蓋式。預壓(ya)方式有定位預壓(ya)（雙螺(luo)母(mu)方式、位預壓(ya)方式）、定壓(ya)預壓(ya)。可(ke)根據用(yong)途選擇適(shi)當(dang)類(lei)型。絲(si)桿有高精(jing)度(du)研磨加工的(de)精(jing)密(mi)滾(gun)(gun)(gun)珠(zhu)(zhu)(zhu)絲(si)杠(gang)(gang)（精(jing)度(du)分(fen)為(wei)(wei)從CO-C7的(de)6個等(deng)級(ji)）和(he)經高精(jing)度(du)冷(leng)軋(ya)(ya)(ya)加工成(cheng)型的(de)冷(leng)軋(ya)(ya)(ya)滾(gun)(gun)(gun)珠(zhu)(zhu)(zhu)絲(si)杠(gang)(gang)軸(zhou)(zhou)承(cheng)（精(jing)度(du)分(fen)為(wei)(wei)從C7-C10的(de)3個等(deng)級(ji)）。另外(wai)，為(wei)(wei)應付用(yong)戶(hu)急需交貨的(de)情況，還有已對軸(zhou)(zhou)端(duan)部(bu)(bu)進行(xing)了(le)加工的(de)成(cheng)品(pin)，可(ke)自由(you)對軸(zhou)(zhou)端(duan)部(bu)(bu)進行(xing)追(zhui)加工的(de)半成(cheng)品(pin)及冷(leng)軋(ya)(ya)(ya)滾(gun)(gun)(gun)珠(zhu)(zhu)(zhu)絲(si)杠(gang)(gang)軸(zhou)(zhou)承(cheng)。作為(wei)(wei)此軸(zhou)(zhou)承(cheng)的(de)周邊零部(bu)(bu)件，在(zai)使用(yong)所必要的(de)絲(si)杠(gang)(gang)支撐單(dan)元、螺(luo)母(mu)支座、鎖緊螺(luo)母(mu)等(deng)也已被標(biao)準(zhun)化生(sheng)產了(le)，可(ke)供用(yong)戶(hu)選擇使用(yong)。
