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. Standard plate casters have kingpins that securely join the casters' mounting plates to their frames. They are used in nearly every industry and are the most common type of caster used for general purpose applications. The casters' mounting plates install onto the bottom of machinery, carts, or other equipment, and the casters allow the equipment to roll to reduce effort when moving or repositioning it. These casters are available in swivel and rigid versions. The swivel casters can rotate 360°, allowing equipment to change directions while rolling. The rigid casters roll in a straight line. Two rigid plate casters will often be paired with two swivel casters to allow the equipment to both maneuver around curves and obstacles and maintain a straight course while rolling. This listing is for each.
