冲压外圈滚针轴承
Drawn Cup Needle Roller Bearings 冲压外圈滚针轴承
冲压外圈滚针轴承HK2520-2RS是我司传统产品,HK2520-2RS此轴承的外圈是用薄钢板精密冲压成形的，结构空间小，且具有较大负荷容量。适用于安装空间受到限制和壳体孔不宜作为滚道的场合。且压入轴承座孔后不必进一步轴向定位。

压外圈滚针轴承是用ST14钢板精密冲压而成形并经高温碳氮共渗处理，其特点是剖面高度极小，且具有极强载荷容量，采用高刚性保持架引导G2级滚针线状外圈滚道，使其更好地平行于轴线．

　　该类滚针轴承的外圈与轴承箱采用静配合，不需要轴向固定装置。即使在高速大负荷条件下，也能充分保持轴承功能。另外，因贮脂容积大，可长期不加润滑脂，也能保证滚针轴承长期灵活旋转，设备运转流畅．

 说明：

 1.表中所列基本额定载荷、极限转速和重量，仅供选择参考用。

 2.轴承的保持架如由塑料制成，在型号后加TN，允许工作温度：120℃连续，180℃短期。

 3.脂润滑时，极限转速为表列数值的60%。

 Note:

 1.These load, speed and mass is reference of choice only.  

 2.If the cages are made of plastics, suffix "TN" is added to the bearing No.,the maximum allowable 

   working themperrature is 120℃ in continuous working and 180℃ in short working.

 3.With grease lubrication, 60% of these limiting speed will apply.
