求翻译：滚针轴承是带有圆柱滚子的轴承，圆柱滚子同其直径相比，较为细长。这些滚子称为滚针。这些轴承虽然横载面小，但有很高的载荷能力，因此滚针轴承非常适用于径向空间有限的轴承配置。冲压外圈滚针轴承冲压外圈滚针轴承的外圈是具有适当的游隙被压入具有适当硬度和加工精度的轴承座孔后可获得所要求的形状和尺寸精度，因此内接圆径在压入适当硬度和加工精度的环规后进行测定。是什么意思？

Needle roller bearings with cylindrical roller bearings, cylindrical roller, more slender than its diameter. These roller called a needle. These bearings, small transverse cross high load capacity needle roller bearings ideally suited for radial space is limited bearing configuration. Needle roller

It is needle roller bearings with a cylindrical roller bearings, cylindrical roller with a diameter less than for SLIM. These roller called needle. Though these bearings contained small, but have a very high load capacity, the needle bearings are ideal for bearing radial space is limited. Drawn cup

Needle roller bearing with a cylindrical roller bearing, cylindrical roller with compared to its diameter, more slender. These rollers are called needle. While those bearing cross section smaller, but have a high load carrying capacity, so needle works well for bearing arrangement of radial space is
