Where it fits. Thermoplastic polyurethane is the general-purpose upgrade tread. It is non-marking, resists oils and most mild chemicals, and carries more load than rubber at the same diameter without the noise of a hard tread. TPU holds its shape under sustained static load, so carts parked loaded overnight are less prone to flat spots. This swivel model rotates a full 360 degrees and is normally specified two per cart with two rigid casters at the opposite end, or four per cart where the equipment has to move sideways in tight aisles.
Construction. The yoke is formed from zinc-plated steel for corrosion resistance. It mounts on a 4″ x 4-1/2″ top plate with 3-1/8″ x 2-1/16″ bolt-hole centers. A 1/2″ steel Quad X bearing rides on a 1/2″ axle for smooth, low-effort rolling.
Load and duty. The 800 lb rating is per caster. Standard practice is to size a four-caster set assuming three casters carry the load, so this model supports roughly a 2,400 lb cart with margin for shock loading and uneven floors. Continuous operating range is -30°F to 140°F.
About Series 40. Our medium and heavy duty line is engineered to make light work of heavy loads, handling up to 1,500 lb per caster with ergonomics and maneuverability in mind so that a loaded cart stays manageable. The line continues to expand as new industries bring us new requirements.
