Centralizers are an important part of any logging tool string as they are responsible for supporting and centering the tools. Low friction roller centralizers are designed specifically for this purpose and feature precision-engineered arms and low friction double rollers. These centralizers also have an electrical feedthrough, allowing them to be placed anywhere in the tool string.
Low friction roller centralizers are designed to support and center logging tools accurately in vertical or deviated wells. The arms are precision engineered and mechanically linked to provide a constant radial force through the full operational range with low friction double rollers to enable smooth travel in and out of the well. The arm assembly floats on the mandrel between collars to minimize the closing force required when re-entering tubing or passing a restriction. The centralizer contains an electrical feedthrough allowing it to be placed anywhere in the tool string.
