Abstract: A rod guide is provided for centering a sucker rod within a tubular string that powers the pump within a well bore. The rod guide comprises a spool securable to the rod and having tipper and lower end members thereon, and a plastic material sleeve extending between the upper and lower end members. The sleeve may be mounted to the rod during a molding operation. The rod guide further includes a guide body which may be machined from an ultra-high molecular weight polyethylene material which has desired abrasive and wear characteristics. In one embodiment, the body is rotatable about the spool. A slot within the guide body and scalloped-shaped cut-outs at both ends of the guide body provide fluid communication between an annulus formed between the O.D. of the sleeve portion of the spool and the I.D. of the guide body.
