Replace worn or squeaky office chair wheels with this set of five 3-inch polyurethane casters, sized to fit most standard chairs with a 0.43-inch stem. Each wheel rides on dual ball bearings for a smooth, quiet roll instead of the grinding and scraping that scratches hardwood floors, while the molded polyurethane tread stays gentle on carpet too. The thickened metal yoke is finished to resist rust, so the casters hold up under daily rolling back and forth from a desk. A full 360-degree swivel lets the chair turn and reposition without catching, and the low 0.86-inch installation height keeps the fit compatible with the original hardware on gaming chairs, task chairs, and drafting stools. Together the five wheels support up to 130 lbs, making this a simple swap for anyone whose factory-installed casters have gone loud, stiff, or worn flat.
