High grade liquid cast polyurethane.
90-95 Durometer (Shore A).
50° to +200° F. intermittent; 0° to 180° F continuous. Not damaged by occasional steam cleaning.
Souble sealed, maintenance free, superior rollability aids manual applications, not recommended if shock loading is prevalent.
traditional anti-friction bearing, best for manual applications where shock loading (but no side thrust) is prevalent.
Best for most severe heavy duty and power-towed applications.
For the extra tough jobs requiring protective polyurethane treads, Hamilton manufacturers these top-of-the-line Superlast® Wheels. The extra-thick (1") blue treads (hardness of 90-95 Shore A) are liquid cast and chemically bonded to solid-web, drop forged steel centers.
Precision tapered roller bearings are standard, making these high capacity wheels ideal for towing at limited speeds. Ball-check lubrication fittings are provided in the hubs.
