外圈雙擋邊（或雙鎖圈）帶保持架滾針軸承 NA、NKI型
可分別安裝內圈和外圈（帶鎖圈、全套滾針和保持架），權限轉速高，分單列和雙列兩種。
如果軸不能用來作為滾道，即若將軸淬硬用研磨不可能或不經濟時，則可采用此類帶內圈的滾針軸承。
實體套圈滾針軸承無內圈有保持架滾針軸承
NA、NKI型軸承不帶內圈即為RNA、NK型滾針軸承。
此種軸承無內圈，適用于徑向安裝尺寸受限制的支承結構，與軸承相配的軸頸直接作為滾動面。作為滾道面的軸，必須淬硬件并進行研磨，而且只有將其加工到適當的尺寸和形狀精度時，整套滾針軸承才能較高的壽命及運行精度。同時，由于無內圈，因此軸的直徑也可作適當加大，從而也增加了剛性
體套圈滾針軸承帶或不帶內圈的密封滾針軸承
單面或雙面密封的滾針軸承可以有效地防止臟物的侵入，軸承內已填入適量的鋰基潤滑脂。該類軸承的內圈比外圈寬，這使得軸承在軸相對軸承箱有微量位移時也可保證密封良好而免致軸承受污染。軸承的內圈也有潤滑油孔，可以根據配置的需要，由外圈或內圈補充潤滑
