TN=塑料保持架，允许工作温度：120°C连续；180°C短期。

1）F是内圈滚道直径，Fw是具F6公差范围内的滚针内切圆直径。

2)当轴承外圈（有外圈柱表面）装入具有一般配合的座孔中时，使用基本额定负荷Cr和Cor；当用作支承滚轮时，使用额定负荷Cw和Cow。

3）使用油润滑时，极限转速增加约30％。

1）TN=plastic cage,permissible operating temperature:120°C(continuous operation).

F=raceway diameter of innerring.

Fw=needle roller enveloping circle in the tolerance zone F6.

2)The basic load ratings C and C0 apply if the bearing outerring(with cylindrical outside surface) is mounted in a housing bore with the normal rolling bearing fit; when used as a track roller,the load ratings Cw and Cow apply.

3)Limiting speed for grease lubrication.with oil lubrication,the speed can be increased by approximately 30%.

1）后缀“X”表示为圆柱形外表面，例如：NATR 5 X或NATR 5 PP X。

2)当轴承外圈（有外圈柱表面）装入具有一般配合的座孔中时，使用基本额定负荷Cr和Cor；当用支承作滚轮时，使用额定负荷Cw和Cow。

3）使用油润滑时，极限转速增加约30％。*密封型的极限转速应减低30％。

1）The suffix Xindicates a cylindrical outside surface e.g.NATR 5 X or NATR 5 PP X.

2)The basic load ratings C and C0 apply if the bearing outer ring(with cylindrical outside surface) is mounted in a housing bore with the normal rolling bearing fit; when used as a track roller,the load ratings Cw and Cow apply.

3)Limiting speed for grease lubrication. with oil lubrication,the speed can be increased by approximately 30% except for the sealed executions.*For the sealed version the limiting speed ng for grease lubrication should be reduced by approximately 30%.
