IKO - Needle Roller Bearings With Separable Cage Without Inner Ring - RNAFW Series (IKO) (Part Numbers)

IKO - Needle Roller Bearings With Separable Cage Without Inner Ring - RNAFW Series (IKO)
  • Volume Discount

In Needle Roller Bearings with Separable Cage, the inner ring, outer ring and Needle Roller Cage are combined, and they can be separated easily. This type has a simple structure with high accuracy. In addition, the radial clearance can be freely chosen by selecting and combining these component parts. As Needle Roller Cages are used, these bearings have excellent rotational performance. These bearings are most suitable for mass-production high accuracy products such as machine tools, textile machinery, and printing machines.

The single-row as well as the double-row types are available with the same sectional height, and either of them can be selected according to load conditions.
