The LiMAR Multi Roller Wheel Sub can be positioned at various points along the length of a toolstring to effectively lift the string from off of the tubing wall and onto the roller wheels.
The LiMAR® design is short and compact with six roller wheels per assembly - each offset at 60 degrees to each other. 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.
