Product Description

Seal Ring Needle Bearings NA-RS Series are essentially Cylindrical Roller Bearings except that their cylindrical rollers have a length 3 to 10 times their diameter, Needle Roller Bearings NA-RS Series are also essentially bearings that utilize small & cylindric rollers. 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.

Features
Needle Bearings With Inner NA-RS Series have a high load carrying capacity in addition to their low cross-section and stiffness. They are especially suitable for bearing arrangements where radial space is limited because needle roller bearings only carry pure radial load and can not limit the axial displacement of shaft relative to the housing. It is important to ensure that inner ring axis and outer ring axis must be aligned during mounting the bearings.



Needle Bearings With Inner NA-RS 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.
High stiffness
Due to their large number of small-diameter rollers, needle roller and cage assemblies have high stiffness.
