Needle bearing IRT1016-2 is a of cup needle roller bearings and it is a bearing having small friction coefficient and excellent rotational performance designed.With the purpose of increasing the load area effectively,the radial gap of needle roller bearing IRT1016-2 is smaller than the general needle roller bearings. Therefore, it alleviates the impact load, and a stable long life is gained. Since the stud undergoes screw processing and stepped processing, they can be attached easily.
