Standard Sucker Rod Centralizer

1. The sliding sleeve scentralizer adopts a three-curved surface wear reduction design to change the traditional contact mode. The centralizer increases the contact area of the surface, makes the force more uniform, and improves the anti-eccentric wear performance. 2. The sliding sleeve centralizer is a downhole supporting device. The sliding sleeve centralizer can avoid eccentric wear damage between the sucker rod and the oil pipe and protect the integrity of the oil pipe. 3. The sliding sleeve sucker rod centralizer can center the sucker rod in the well to avoid metal-to-metal contact.
