中文品名：滚针滚子轴承

Series NTN-RNA 4900, Without Inner Ring

系列NTN-RNA4900, 不带内环

The needle like small diameter rollers of these bearings are cylindrical in shape and can be fitted to spindles where you do not want a large outside mount as in roller bearings.  When ordering, specify the INSIDE and OUTSIDE DIAMETER, the THICKNESS and whether the bearing should be WITH or WITHOUT inner rings.　　

这些轴承的针状小直径滚子是圆柱形的，可以安装在您不想要像滚子轴承那样大的外部安装的主轴上。订购时，请注明内径和外径、厚度以及轴承是否应该有内圈。
