Features of Roller Centralizer
- The capability of the roller centralizer is better than other type centralizer because of rigid body and friction between the rollers. 
- Roller centralizers provide superior wear resistance.
-The smaller roller-contact area reduces the risk of differential sticking and maintains standoff when running casing.
- The roller and axle's relationship ensures that axle shear stresses remain within elastic limits, preventing permanent deformation. 
- Rollers won't break.
