向心滾針和保持架組件(滾針軸承)是獨(dú)立的滾動(dòng)元件，其保持架的兩引導(dǎo)面間距寬廣，既能精確引導(dǎo)滾針，又可保持滾針的正確位置。該類軸承適用于軸和座孔可作為滾道的場(chǎng)合，只須將軸和軸承座孔滾道加工至規(guī)定的尺寸精度和幾何精度，即可確保最小空間的高旋轉(zhuǎn)精度。向心滾針和保持架組件是由保持架和滾針組成的完整軸承單元，主要用于 軸和軸承箱可作為滾道場(chǎng)合，且有以最小徑向結(jié)構(gòu)空間下承受高負(fù)荷和高剛性的 能力。在高精度的軸和座孔滾道下，可獲得較高的旋轉(zhuǎn)精度；工作間隙可根據(jù)滾 針、安裝軸和座孔進(jìn)行調(diào)整，安裝十分便利，是在惡劣條件下使用的非常經(jīng)濟(jì)的 軸承。 對(duì)于無法淬硬的軸和座孔，可使用本公司專門生產(chǎn)的IR標(biāo)準(zhǔn)圈進(jìn)行鑲套處理； 廣泛用于汽車、摩托車、工程機(jī)械的傳動(dòng)軸和齒輪箱及連桿軸配置。 △結(jié)構(gòu)形式
該類軸承有單列K型和雙列K…ZW型，對(duì)整體無法裝配時(shí)，如曲軸凹頸處的支 承，可使用特殊的剖分結(jié)構(gòu)單列K…D型和雙列K…ZWD型。常州仟盈軸承有限公司并設(shè)計(jì)有車制 和沖壓、M型和K型等多種結(jié)構(gòu)型式供不同場(chǎng)合選擇使用，也可根據(jù)用戶特殊結(jié)構(gòu) 要求設(shè)計(jì)。
