RNA4902 NA NKI NK GR15 Heavy Duty Needle Roller Bearings For Textile Machine

High precision Open Seal Steel needle roller bearing without shoulder with inner ring/RNA4902

Description:

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 situation where the shaft or housing has the swinging motion. In general, the needle roller bearing only withstands the radial load, not the axial load. When the 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.

Because of no inner ring, this needle roller bearing is suitable for parts of which the radial size is limited.The surface of shaft journal fitted with it is acted directly as rolling surface. lt is requested that the surface hardness of shaft journal be no less than HRC60 and the surface roughness Ra value, no more than 0.63hm.This kind of bearing does not limit the axial shift of shaft and housing .

Features:
