Abstract
An antirotation stabilizer may include one or more antirotation pads extending from a stabilizer body. Each antirotation pad may be positioned at least partially within a recess formed in the stabilizer body. Each antirotation pad may be coupled to a torsion bar. The torsion bar may couple between the antirotation pad and the stabilizer body and may be under torsional loading such that the antirotation pad is extended from the stabilizer body. The antirotation stabilizer may include one or more rollers.
