Features
They centralize the rod string in the tubing, and the rolling action of the wheels inside the tubing walls during stroking reduces friction and wear caused by the rods slapping or rubbing the tubing.
With proper use of the Wheeled Rod Guide couplings and effective chemical treatment programs, several operators have extended by an average of four times the operating periods between having to "pull and service" wells because of sucker rod or tubing wear.
