A magnetic support sucker rod centralizer, righting sleeve is provided with a magnetic strip mounting groove, magnetic mounting groove length is short, the installation in the installation groove magnetic stripe, the magnetic stripe mounting groove magnetic stripe outward extrusion, is sheathed on the abrasion resistant bush centralizer, corrosion resistant bearing outer wall of the magnetic stripe spacing, and the external threads fixed sleeve thread abrasion bearing at the lower part of the connection, produce axial force and radial force between the magnetic stripe and the tubing, the utility model is temporarily fixed on the inner wall of the pipe, the utility model can not in the rough pipe on the inner surface of friction and wear, the friction between sucker rod and tubing wear and converted to smoke rod friction and abrasion between bearing and wear between sucker rod and abrasion resistant bearing small friction coefficient, friction and abrasion, long service life, therefore, the magnetic sucker rod centralizer can support The utility model has the advantages of simple structure and easy installation, and ensures that the oil pipe and the sucker rod are not worn and the production cycle of the oil well is prolonged.
