Product Description
Seal Ring Needle Bearings RNA-RS Series is suitable for suitable for parts of which the radial size is limited. The surface of shaft journal fitted with it is acted directly as rolling surface. Needle Roller Bearings RNA-RS Series is requested that the surface hardness of shaft journal be no less than HRC60 and the surface roughness Ra value, no more than 0.63μm. Needle Bearings With Inner Ring RNA-RS does not limited in axial displacement for shaft or shell, high limit speed
Needle Roller Bearings RNA-RS Series Features
Lowest cross section among rolling bearings
Seal Ring Needle Bearings RNA-RS Series In applications where less space is available, needle roller and cage assemblies offer a very compact solution.
High load carrying capacity
Due to their large number of rollers, needle roller and cage assemblies have a high load carrying capacity.
High stiffness
Due to their large number of small-diameter rollers, needle roller and cage assemblies have high stiffness.
