INA滾(gun)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)承(cheng)(cheng)是用來支持(chi)過引導(dao)相(xiang)互間移(yi)動(dong)(dong)(dong)(dong)(dong)的部件(jian)(jian)。它們(men)必須支持(chi)和傳(chuan)遞在這鐘情況(kuang)下(xia)產(chan)生(sheng)的力(li)。通過滾(gun)動(dong)(dong)(dong)(dong)(dong)元件(jian)(jian)，將滾(gun)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)承(cheng)(cheng)配置(zhi)中的軸(zhou)(zhou)承(cheng)(cheng)配置(zhi)元件(jian)(jian)相(xiang)互分離 - 滾(gun)動(dong)(dong)(dong)(dong)(dong)元件(jian)(jian) - 滑(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)(dong)軸(zhou)(zhou)承(cheng)(cheng)配置(zhi)中的活動(dong)(dong)(dong)(dong)(dong)組件(jian)(jian) - 通常為軸(zhou)(zhou)，立(li)柱或帶(dai)鋼(gang) - 在靜(jing)態軸(zhou)(zhou)承(cheng)(cheng)襯(chen)墊、軸(zhou)(zhou)承(cheng)(cheng)外(wai)圈或滑(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)(dong)條的滑(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)(dong)表面上滑(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)(dong)。直接在軸(zhou)(zhou)承(cheng)(cheng)體的滑(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)(dong)層(ceng)和被制成部件(jian)(jian)間產(chan)生(sheng)滑(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)(dong)運動(dong)(dong)(dong)(dong)(dong)。通過深入(ru)潤滑(hua)(hua)(hua)(hua)或一個(ge)用于一個(ge)承(cheng)(cheng)載體的固體層(ceng)保證潤滑(hua)(hua)(hua)(hua)。在徑向(xiang)運動(dong)(dong)(dong)(dong)(dong)中，軸(zhou)(zhou)和滑(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)(dong)層(ceng)之間的間隙(xi)保證了滑(hua)(hua)(hua)(hua)動(dong)(dong)(dong)(dong)(dong)伙(huo)伴的可動(dong)(dong)(dong)(dong)(dong)性。

   INA滾(gun)動(dong)軸(zhou)(zhou)承可作為徑(jing)向(xiang)軸(zhou)(zhou)承、軸(zhou)(zhou)向(xiang)軸(zhou)(zhou)承、帶鋼(gang)、外圈和(he)很(hen)多其(qi)他設計。它們運(yun)行安(an)靜，并(bing)特(te)別適(shi)合在相對緩(huan)慢的(de)(de)旋轉(zhuan)(zhuan)下支持高載(zai)荷的(de)(de)位置(zhi)使用(yong)(yong)，也適(shi)用(yong)(yong)于旋轉(zhuan)(zhuan)運(yun)動(dong)和(he)高/低溫環境。因(yin)為其(qi)通用(yong)(yong)特(te)性，它們幾乎使用(yong)(yong)在所(suo)有工業領域，尤(you)其(qi)是那些可用(yong)(yong)的(de)(de)軸(zhou)(zhou)承配置(zhi)空間(jian)很(hen)有限(xian)的(de)(de)地方。

  INA滾(gun)(gun)(gun)(gun)(gun)動(dong)(dong)軸(zhou)承一般(ban)(ban)包含兩(liang)個帶完整(zheng)滾(gun)(gun)(gun)(gun)(gun)道的(de)(de)軸(zhou)承圈。滾(gun)(gun)(gun)(gun)(gun)動(dong)(dong)元件安裝(zhuang)在(zai)圈之間，并(bing)在(zai)滾(gun)(gun)(gun)(gun)(gun)道上滾(gun)(gun)(gun)(gun)(gun)動(dong)(dong)。滾(gun)(gun)(gun)(gun)(gun)動(dong)(dong)部(bu)(bu)件可(ke)以是(shi)球(qiu)、圓柱(zhu)滾(gun)(gun)(gun)(gun)(gun)子、滾(gun)(gun)(gun)(gun)(gun)針滾(gun)(gun)(gun)(gun)(gun)子、圓錐滾(gun)(gun)(gun)(gun)(gun)子或桶(tong)狀滾(gun)(gun)(gun)(gun)(gun)子。滾(gun)(gun)(gun)(gun)(gun)動(dong)(dong)部(bu)(bu)件一般(ban)(ban)通過保持(chi)架(jia)引導(dao)，使它們(men)相(xiang)互間保持(chi)統(tong)一的(de)(de)距離(li)，防止相(xiang)互接觸(chu)。在(zai)滾(gun)(gun)(gun)(gun)(gun)針滾(gun)(gun)(gun)(gun)(gun)子軸(zhou)承和(he)拉筋調心滾(gun)(gun)(gun)(gun)(gun)子軸(zhou)承中(zhong)，保持(chi)架(jia)也(ye)確保滾(gun)(gun)(gun)(gun)(gun)動(dong)(dong)部(bu)(bu)件的(de)(de)位置(zhi)正確。軸(zhou)承可(ke)被拆卸時，保持(chi)架(jia)將滾(gun)(gun)(gun)(gun)(gun)動(dong)(dong)部(bu)(bu)件集(ji)中(zhong)在(zai)一起，并(bing)使軸(zhou)承的(de)(de)安裝(zhuang)更(geng)加簡便。針對特殊(shu)應用(yong)，帶全補足球(qiu)的(de)(de)滾(gun)(gun)(gun)(gun)(gun)動(dong)(dong)軸(zhou)承，可(ke)使用(yong)圓柱(zhu)滾(gun)(gun)(gun)(gun)(gun)子或滾(gun)(gun)(gun)(gun)(gun)針。

   INA滾動(dong)軸(zhou)承(cheng)特(te)點和應(ying)用：

   每個(ge)滾(gun)子軸承(cheng)設計的特點是使其特別適合具(ju)體的軸承(cheng)應用。不可能制定(ding)普遍有效的規(gui)則用于軸承(cheng)類型的選擇，因為通(tong)常須考慮和(he)權衡若干因素。除了(le)載荷和(he)速度，通(tong)常也須注(zhu)意溫度、潤滑、振動、安裝、維護等的影(ying)響。很多情況(kuang)下，至少一個(ge)軸承(cheng)主要尺寸－通(tong)常為鉆(zhan)孔直(zhi)徑－已經通(tong)過(guo)相鄰(lin)結構確定(ding)。

   另一個特點(dian)是軸(zhou)(zhou)(zhou)承如何對軸(zhou)(zhou)(zhou)進行引導。有允(yun)許(xu)軸(zhou)(zhou)(zhou)向位移(yi)的(de)軸(zhou)(zhou)(zhou)承，有在(zai)一個或兩個軸(zhou)(zhou)(zhou)向方向引導一個軸(zhou)(zhou)(zhou)的(de)軸(zhou)(zhou)(zhou)承和允(yun)許(xu)角(jiao)度調整的(de)軸(zhou)(zhou)(zhou)承和允(yun)許(xu)相(xiang)鄰結(jie)構偏心的(de)軸(zhou)(zhou)(zhou)承。
