Polyurethane wheels-the protective wheel that wears like steel-is Hamilton's highest quality urethane, liquid cast to a thickness of approximately 1/2" and chemically bonded onto heavy-duty iron wheel centers. The distinctive green treads are chemically inert, non-sparking, non-conductive, impervious to oil, ozone, grease and most solvents, and will not mark floors. Polyurethane wheels are also guaranteed against tread separation for one year in ordinary free-wheeling applications (contact factory for excepted applications). They are available without bearings, with straight roller bearings, or with precision tapered bearings as listed below. All sizes except the 3 " and 4" diameter include ball-check lubrication fittings in the hub.

Poly-Soft® Wheels Series SP — Cap. to 2,800 lbs.
Hamilton Caster proudly introduces a new softer polyurethane tread wheel—Poly-Soft® — formulated for a quieter operation and greater resistance to foreign objects and debris (F.O.D.). As the name implies, Poly-Soft® wheel tread hardness measures 82-85D (Shore A scale) vs. the harder Duralast® 90-95D (Shore A). The newly formulated polyurethane wheel has found popularity among automotive plants and those customers wanting to lower factory noise levels, and improve floor protection.

Erg-Tech Wheels Series AY — Cap. to 1,700 lbs.
Hamilton’s Erg-Tech wheels, polyurethane on aluminum, come in two breeds. The new 622 and 822 models are the latest polyurethane wheels made popular by automotive manufacturers across the country. The unique half-round or donut-type tread is combined with maintenance-free precision ball bearings to provide effortless rolling. A generous amount of polyurethane is bonded both mechanically and chemically to a large fin that extends from the center of the core providing excellent performance in the most demanding of applications. Engineers then specified a softer polyurethane with a durometer of 80 (Shore A) to ensure greater traction and to run quieter than traditional urethanes.

Unilast® Wheels Series UY — Cap. to 1,500 lbs.
Unilast® polyurethane wheels are Hamilton's line of solid elastomer wheels designed for medium to heavy duty loads. Equipped with Delrin® or Precision ball bearings, these high performance wheels are steam cleanable and well suited for hostile environments, as they are not affected by blood, brine, salt, grease, oils and many other harsh chemicals. Standard hardness of the Unilast® is 75-80 Shore D.
Poly-Tech® Wheels Series NF — Cap. to 1,200 lbs.
These attractive and durable industrial wheels feature a resilient tread of red polyurethane (90-95 Durometer Shore A) mechanically bonded to a specially designed white center of harder polypropylene. The result is a non-marking, contemporary looking wheel ideally suited for hospitals, schools, restaurants, hotels and motels, office buildings or light industry.
