The LiMAR Multi Roller Wheel Sub – Swivel Type 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.
An integral Swivel Sub situated either above or below the rollers prevents any lateral friction occurring from rotational torque generated between the Roller Subs as they are conveyed into and out of a well. The LiMAR® design is short and compact with six roller wheels per assembly - each offset at 60 degrees to each other. Particularly in highly deviated wells friction occurs between the full contact area of the toolstring and the tubing wall. The roller wheels rotate freely on hardened axles to reduce friction.
