Also known as universal casters, these casters press-fit into standard 1" OD wire shelving posts. Friction on their stem's grip ring holds them in place. Wheels have a hard polypropylene core for strength under a polyurethane tread that combines the abrasion resistance of plastic with the shock-absorbing qualities of rubber. They can be used on smooth and rough floors and in areas with debris. Flanged-sleeve wheel bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Casters have shielded dual-raceway swivel bearings for the smoothest swiveling and protection from dust and debris.
