Подшипники игольчатые без внутреннего кольца и с внутренним кольцом это подшипники качения для высоких нагрузок с пространственной несложной конструкцией. Игольчатые ролики расположены параллельно оси в прочном сепараторе и имеют фиксированный допуск диаметра 2 мкм. Наружное кольцо с бортиками и сепаратор с игольчатыми роликами составляют одно целое.
Игольчатые подшипники с бортиками с внутренним кольцом поставляются таких типов: NKI, NKIS, NA48, NA49, NA69.
Конструкция с внутренним кольцом используется тогда, если нет возможности на валу сделать дорожку качения. Наружное кольцо с сепаратором и внутреннее кольцо могут быть собраны по отдельности. Учитывая производственные допуски и температурное расширение присоединительных частей в эксплуатации, не должны превышаться значения сдвига „s“, указанные в таблицах размеров. В случае если табличные размеры недостаточны, разрешено игольчатые подшипники комбинировать с более широкими кольцами IR и LR, чем те которые указаны в таблицах размеров. Для смазывания подшипники имеют канавку и отверстие, за исключением подшипников NKI с d ≤ 7 мм.
