滾珠(zhu)絲(si)杠是將(jiang)(jiang)回轉(zhuan)運(yun)(yun)動轉(zhuan)化(hua)為(wei)直線運(yun)(yun)動，或(huo)將(jiang)(jiang)直線運(yun)(yun)動轉(zhuan)化(hua)為(wei)回轉(zhuan)運(yun)(yun)動的理想(xiang)的產品。

滾(gun)珠絲杠是工具(ju)(ju)(ju)機(ji)械和精密(mi)機(ji)械上最(zui)常(chang)使(shi)用(yong)的傳動元件，其主要功能是將旋轉運(yun)動轉換成線(xian)性(xing)運(yun)動，或(huo)將扭(niu)矩(ju)轉換成軸向(xiang)反(fan)復(fu)作用(yong)力，同時(shi)兼具(ju)(ju)(ju)高精度、可逆(ni)性(xing)和高效率的特點。由(you)于具(ju)(ju)(ju)有很小的摩擦(ca)阻力，滾(gun)珠絲杠被廣(guang)泛應(ying)用(yong)于各種(zhong)工業設備和精密(mi)儀(yi)器。

滾(gun)珠(zhu)絲(si)(si)杠由螺(luo)(luo)桿、螺(luo)(luo)母(mu)、鋼球、預壓片、反向器、防塵器組成(cheng)(cheng)(cheng)(cheng)。它(ta)的(de)功能是(shi)將(jiang)旋轉運(yun)(yun)動(dong)(dong)(dong)(dong)轉化成(cheng)(cheng)(cheng)(cheng)直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)，這是(shi)艾克姆(mu)螺(luo)(luo)桿的(de)進一(yi)步延(yan)伸和(he)發展(zhan)，這項發展(zhan)的(de)重要(yao)意義(yi)就是(shi)將(jiang)軸承(cheng)從滑(hua)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)作變成(cheng)(cheng)(cheng)(cheng)滾(gun)動(dong)(dong)(dong)(dong)動(dong)(dong)(dong)(dong)作。當(dang)滾(gun)珠(zhu)絲(si)(si)杠作為(wei)主動(dong)(dong)(dong)(dong)體時(shi)，螺(luo)(luo)母(mu)就會隨絲(si)(si)桿的(de)轉動(dong)(dong)(dong)(dong)角度按照對(dui)應規格的(de)導程(cheng)轉化成(cheng)(cheng)(cheng)(cheng)直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)，被動(dong)(dong)(dong)(dong)工件可以通(tong)過螺(luo)(luo)母(mu)座和(he)螺(luo)(luo)母(mu)連接(jie)，從而(er)實現對(dui)應的(de)直(zhi)線運(yun)(yun)動(dong)(dong)(dong)(dong)。

滾(gun)珠(zhu)(zhu)絲杠軸(zhou)承(cheng)為(wei)(wei)適應(ying)各(ge)種用(yong)(yong)途，提供了標準化種類繁多的產(chan)品(pin)(pin)。廣泛應(ying)用(yong)(yong)于機床(chuang)，滾(gun)珠(zhu)(zhu)的循環方(fang)式有循環導管式、循環器(qi)式、端蓋式。預(yu)壓(ya)方(fang)式有定(ding)位預(yu)壓(ya)（雙螺(luo)母方(fang)式、位預(yu)壓(ya)方(fang)式）、定(ding)壓(ya)預(yu)壓(ya)。可根據(ju)用(yong)(yong)途選擇適當(dang)類型(xing)。絲桿有高精(jing)度(du)(du)研磨加(jia)(jia)工的精(jing)密滾(gun)珠(zhu)(zhu)絲杠（精(jing)度(du)(du)分為(wei)(wei)從CO-C7的6個(ge)等(deng)級）和經高精(jing)度(du)(du)冷(leng)軋(ya)加(jia)(jia)工成型(xing)的冷(leng)軋(ya)滾(gun)珠(zhu)(zhu)絲杠軸(zhou)承(cheng)（精(jing)度(du)(du)分為(wei)(wei)從C7-C10的3個(ge)等(deng)級）。另外，為(wei)(wei)應(ying)付用(yong)(yong)戶急需(xu)交貨的情況(kuang)，還有已對軸(zhou)端部(bu)(bu)進行了加(jia)(jia)工的成品(pin)(pin)，可自由對軸(zhou)端部(bu)(bu)進行追(zhui)加(jia)(jia)工的半成品(pin)(pin)及冷(leng)軋(ya)滾(gun)珠(zhu)(zhu)絲杠軸(zhou)承(cheng)。作為(wei)(wei)此軸(zhou)承(cheng)的周(zhou)邊零部(bu)(bu)件，在(zai)使用(yong)(yong)所必要的絲杠支撐(cheng)單元、螺(luo)母支座、鎖(suo)緊(jin)螺(luo)母等(deng)也已被標準化生產(chan)了，可供用(yong)(yong)戶選擇使用(yong)(yong)。
