Entity Bushed Needle Roller Bearing 實(shí)體套圈滾針軸承
實(shí)體套圈滾針軸承是我司傳統(tǒng)優(yōu)勢產(chǎn)品,已經(jīng)有15年的生產(chǎn)經(jīng)驗(yàn).具有精度高,壽命長,包裝精美等特點(diǎn),是代用本司CZB,CZB等我司同類型號實(shí)體滾針軸承的更好選擇.此類軸承我們已于國內(nèi)轉(zhuǎn)向器等國家知名汽車企業(yè)配套,在本司享有一定的知名度.
質(zhì)量是一個(gè)公司生存和發(fā)展的生命線,我們一直堅(jiān)信優(yōu)質(zhì)和良信是企業(yè)發(fā)展壯大的基礎(chǔ),因此我公司很抓質(zhì)量管理,在軸承制造的每一個(gè)環(huán)節(jié),嚴(yán)格把關(guān),盡我們所能為客戶提供更好的產(chǎn)品。正因?yàn)槿绱,我公司產(chǎn)品經(jīng)過EWC質(zhì)量管理體系認(rèn)證,質(zhì)量標(biāo)準(zhǔn)達(dá)到ISO90001全部適用條款要求。
實(shí)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(jié)構(gòu)。 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(jié)構(gòu)。 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(shí)體套圈滾針軸承結(jié)構(gòu)緊湊,徑向尺寸小,負(fù)荷容量大,實(shí)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(fù)荷,不能承受軸向負(fù)荷。當(dāng)有軸向負(fù)荷時(shí),應(yīng)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(zhuǎn)速較低,在主機(jī)轉(zhuǎn)速較高的情況下,應(yīng)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(fù)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(jié)構(gòu)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(yīng)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(dǎo)滾針平行軸線
