DURABUBBLE Bubble Roll for General Use

Extra-heavy-duty standard plate casters have forged steel frames, tapered roller thrust bearings, and forged or welded steel kingpins. They can bear heavier loads, tolerate more frequent use, and withstand more shock and impact from rolling over rough or uneven ground than light-duty, medium-duty, and heavy-duty standard plate casters. The casters are installed onto the bottom of dumpsters, trailer frames, die carts, and other heavy equipment used in industrial areas such as manufacturing plants, construction sites, and assembly plants. Swivel versions of these casters have hardened bearing raceways and large-diameter hardened ball swivel bearings, which are quieter and allow the caster to swivel more smoothly than roller bearings.
