?滑動(dòng)軸承一般由不銹鋼制成，所以它看起來非常光滑，沒有摩擦力和滑動(dòng)阻力，但在工作時(shí)它會(huì)受到來自兩個(gè)油封之間流體壓力不平衡或兩個(gè)固定油封之間運(yùn)動(dòng)摩擦?xí)r會(huì)引起振動(dòng)和滑動(dòng)阻力根據(jù)材料不同（如碳鋼或鑄鐵),滑動(dòng)軸承類型不同。
這意味著使用滑座時(shí)有兩個(gè)工作點(diǎn)（稱為滑摩擦）需要進(jìn)行補(bǔ)償如果需要補(bǔ)償滑座之間的摩擦，應(yīng)在滑座與油封之間安裝一個(gè)內(nèi)圈（稱為滑動(dòng)圈);如果需要補(bǔ)償滑座之間的滑動(dòng)阻力，則應(yīng)在滑動(dòng)圈中裝配滑動(dòng)滾動(dòng)軸承座（稱為滑動(dòng)軸承座）來補(bǔ)償滑座之間的滑動(dòng)阻力而不會(huì)在滑動(dòng)軸承座表面產(chǎn)生振動(dòng)（滑動(dòng)軸承座）。
當(dāng)兩個(gè)球鉸固定在油封上時(shí)，滾動(dòng)軸承所承受的載荷被傳遞到兩個(gè)滑車輪和滑座上滑車輪的載荷為軸向力，滑座的載荷為徑向力當(dāng)滑座為單滾珠軸承時(shí)，滾動(dòng)軸承有一個(gè)很小的徑向力但是如果滑座為雙滾珠軸承時(shí)，徑向力很大滑座徑向力很小時(shí)，當(dāng)單滾珠軸承沒有滾動(dòng)軸承時(shí)，它不會(huì)產(chǎn)生徑向力，因此軸向力也不會(huì)被傳遞到滑座中。
當(dāng)滑座為雙滾珠軸承時(shí)，球鉸在滑動(dòng)時(shí)會(huì)產(chǎn)生徑向力和軸向力，但因?yàn)榛瑒?dòng)軸承內(nèi)面沒有滾動(dòng)軸承時(shí)兩者之間沒有任何作用當(dāng)球鉸轉(zhuǎn)動(dòng)時(shí)就會(huì)產(chǎn)生徑向力和軸向力從而改變球鉸旋轉(zhuǎn)方向所以當(dāng)球鉸轉(zhuǎn)動(dòng)時(shí)，轉(zhuǎn)動(dòng)和滑動(dòng)之間沒有任何關(guān)系。
但是，當(dāng)球鉸轉(zhuǎn)動(dòng)時(shí)將會(huì)對(duì)滑座產(chǎn)生軸向力為了保證滑動(dòng)軸承不會(huì)受到軸向力，應(yīng)在滑座內(nèi)部添加潤滑脂當(dāng)球鉸轉(zhuǎn)動(dòng)時(shí)會(huì)從滑座表面上產(chǎn)生軸向力，因此滑動(dòng)軸承也會(huì)受到軸向力，并且如果滑動(dòng)軸承受到軸向力將會(huì)導(dǎo)致球鉸滾動(dòng)方向改變并且使滑座向右旋轉(zhuǎn)。
