Roller Centralizer
Roller Centralizer
1.375" to 9".
Application
The Roller Centralizer is a mechanical device that centralizes a tool string while it is run in or out of the wellbore. Carbide rollers on the contact points prevent wear on the arms as they expand and contract to fit the wellbore.
The Roller Centralizer is positioned anywhere within the tool string except below the PTF (Pressure Temperature Flow) tool. Often, two Roller Centralizers are used in a string, one at the top and one near the bottom, to further increase the string stability.
