求翻译：滚针轴承实际上可以列入滚柱轴承。它与滚柱轴承最大的不同是径向尺寸小。所以，当载荷较大而径向尺寸较小，退而求之的选择自然是滚针轴承。是什么意思？

Needle roller bearings can actually included in the roller bearings. And roller bearings biggest difference is that the radial dimension is small. So, when the load is large and small radial size, the choice to settle for the natural needle bearing.

Needle roller bearings is actually could be included in roller bearings. With roller bearings it the largest of the radial size is different. Therefore, as the load is large radial sizes are small, and the selection is naturally one of needle roller bearings.

The needle bearing in fact may include the pin bearing.It and the pin bearing biggest difference is the radial direction size is small.Therefore, but when the load the radial direction size is greatly small, draws back asks the choice is naturally the needle bearing.

Needle roller bearing can actually be included in the roller bearings. It with roller bearings, the biggest difference is the radial size small. Therefore, when loading large radial dimensions small, the choice is naturally best needle roller bearings.
