滾針軸承(needle bearing)是帶圓柱滾子的滾子軸承，相對其直徑，滾子既細(xì)又長。這種滾子稱為滾針。盡管具有較小的截面，軸承仍具有較高的負(fù)荷承受能力，滾針軸承裝有細(xì)而長的滾子（滾子直徑D≤5mm，L/D≥2.5，L為滾子長度），因此徑向結(jié)構(gòu)緊湊，其內(nèi)徑尺寸和載荷能力與其它類型軸承相同時，外徑小，特別適用于徑向安裝尺寸受限制的支承結(jié)構(gòu)。
根據(jù)使用場合不同，可選用無內(nèi)圈的軸承或滾針和保持架組件，此時與軸承相配的軸頸表面和外殼孔表面直接作為軸承的內(nèi)、外滾動表面，為保證載荷能力和運轉(zhuǎn)性能與有套圈軸承相同，軸或外殼孔滾道表面的硬度，加工精度和表面質(zhì)量應(yīng)與軸承套圈的滾道相仿。此種軸承僅能承受徑向載荷。
