Model No.: RNAO Series
Needle Roller Without Shoulder RNAO Series are also essentially bearings that utilize small & cylindric rollers. Therefore, the ratio of the bearing outside diameter to the inscribed circle diameter is small, and they have a rather high radial load capacity. Even though they have a low cross section, Needle Roller Bearings have a high radial load capacity and are exceptionally apt for bearing applications where radial space is limited.
Needle Bearing Without Inner Ring RNAO 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 RNAO 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. This type of bearing does not limited in axial displacement for shaft or shell, high limit speed
Needle Roller Bearings RNAO Series Features
Lowest cross section among rolling bearings
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.
Due to their large number of small-diameter rollers, needle roller and cage assemblies have high stiffness.
