1-11/16" Roller Centralizer
The Roller Centralizer is a mechanical device that centralizes a tool string while it is run in or out of the wellbore. Hardened steel 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. Often, two Roller Centralizers are used in a string, one at the top and one near the bottom, to further increase the string stability.

The Roller Centralizer has low friction, allowing it to move easily in and out of the wellbore. The wheels on the Roller Centralizer are easily replaceable and relatively inexpensive.
