Polylast™ Wheels

Capacity Range: 300 - 1,500 lbs.

  • Precision Ball Bearings
Souble sealed, maintenance free, superior rollability aids manual applications, not recommended if shock loading is prevalent.
  • Straight Roller Bearings
Traditional anti-friction bearing, best for manual applications where shock loading (but no side thrust) is prevalent.
 
Hamilton's Polylast™ wheels, polyurethane on aluminum, come in two breeds. The 422, 622 and 822 models are 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.

The end result is a highly durable, easy-rolling, and quiet wheel that can last a lifetime with little or no maintenance required. This wheel design can be specified in additional durometers, colors, and sizes - consult factory. The same wheel design is also available with a cast iron center and can accommodate a 3/4" tapered bearing - consult factory.

The 620 and 820 models represent our traditional poly on aluminum wheels and come standard with a tread hardness of 90-95A. Straight roller bearings are standard in these models and red treads complement their appearance.
