Here's an unusually rugged, industrial duty wheel that looks like a pneumatic or semi-pneumatic, but is puncture proof and provides super cushioning. Tires are extra soft 60 Durometer (±5, Shore A), extra thick rubber permanently vulcanized to cast aluminum wheel centers. Straight roller bearings and lubrication fittings are standard in the hubs.
Super-Flex™ Wheels are recommended for bottlers- trucks, pottery trucks, or even for baggage trailers since they're well suited for outdoor use (tapered roller bearings are available in the larger sizes on special order for high speed applications).
See the Cush-N-Flex
Series for casters utilizing these wheels. Since capacity ratings do not take into account the rollability effort required on soft rubber tires, reduce the ratings in the chart by about 50% for manual operation.
