質量是一個公司生存和發(fā)展的生命線,我們一直堅信優(yōu)質和良信是企業(yè)發(fā)展壯大的基礎,因此我公司很抓質量管理,在軸承制造的每一個環(huán)節(jié),嚴格把關,盡我們所能為客戶提供更好的產(chǎn)品。正因為如此,我公司產(chǎn)品經(jīng)過EWC質量管理體系認證,質量標準達到ISO90001全部適用條款要求。
實體套圈滾針軸承是我司,主要生產(chǎn) NK、NA系列滾針軸承,其中有NK NKS、NKI NKIS、NA49、NA69、NA48、RNA49、RNA69、RNA48等規(guī)格結構。 NK、NA系列滾針軸承,其中有NK NKS、NKI NKIS、NA49、NA69、NA48、RNA49、RNA69、RNA4 8等規(guī)格結構。 NAV、RNAV 是沒有保持器的滾針軸承,滾道里全部裝滿滾針,故又簡稱為滿針!
實體套圈滾針軸承結構緊湊,徑向尺寸小,負荷容量大,實用于徑向輪廓尺寸受到限制的部件中,在軸或外殼有擺動的情況下也廣泛采用。滾針軸承一般只能承受徑向負荷,不能承受軸向負荷。當有軸向負荷時,應和其他軸承組合使用,它不限制軸或外殼的軸向位移。滾針軸承的極限轉速較低,在主機轉速較高的情況下,應盡量選用帶保持架的滾針軸承,和其它類型的滾動軸承相比,在徑向尺寸相同的情況下,滾針軸承負荷容量更大,它的剛性較高,但摩擦力也矩也較大。 此類軸承有多種結構及尺寸系列,要求軸徑或外殼滾動表面硬度,加工精度和表面粗糙度應與軸承套圈相同。所組裝G2滾針,分組批直徑變動量在2um以內(nèi),除滿裝滾針軸承外,均采用高剛性保持架,能夠正確地引導滾針平行軸線
