ROLLER STEM SECTION

The LiMAR® Roller Stem Section provides the necessary mass and reduced friction required for a wireline toolstring to overcome deviation and the upward-acting effects of well pressure.

The roller wheels rotate freely on hardened axles to reduce friction which is commonly known as ’drag’. Particularly in highly deviated wells, drag occurs between the full contact area of the toolstring and the tubing wall. Strategically placed along the length of the wireline toolstring, the mass and drag reducing properties of the LiMAR® Roller Stem also serves to enhance bi-directional impact forces during jarring operations.
