Product Introduction

The solid collar needle roller bearing has compact structure, small radial size and large load carrying capacity. It is suitable for the parts of which the radial overall size is limited. It is also wide applied to the situationwhere the shaft or housing has the swinging motion. In general, the needle roller bearing only withstands theradial load, not the axial load. When thè shaft has axial load, it can be used in combination with other bearings.However, it does not limit the axial shift of shaft or housing. The limiting rotational speed of needle roller bearing is lower. In high rotational speed of main machine, the needle roller bearing with cage shall be chosen as far as possible. In compassion with other types of needle roller bearings, under the situation of same radial size, the needle roller bearing has the large load carrying capacity and high rigidity but has high friction torque.

This kind of bearing has many series with different structure and size. It is requested that the hardness,processing accuracy and surface roughness of shaft journal surface and rolling surface of outer housing be same as those of the collar of bearing. As for the needle roller with G2 class, the diameter varies within 2μm in group. Except the full complement needle roller bearings, they have the rigid cages, which can correctly guide the parallel axis line of needle roller.

RNA,NK series are needle roller bearings without inner ring. They are suitable for parts with limited radial size. Because there is no inner ring, the matching journal surface is directly used as the rolling surface. It is required that the surface hardness should not be lower than HRC60, and the surface roughness Ra value should not be greater than 0.63μm. This kind of bearing does not limit the axial displacement of the shaft or shell, and the limit speed is higher.
