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 rigid model tracks straight and is normally specified two per cart with two swivel casters at the opposite end.
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 dual precision bearing rides on a 1/2″ axle for smooth, low-effort rolling.
Load and duty. The 1,400 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 4,200 lb cart with margin for shock loading and uneven floors. Continuous operating range is -30°F to 140°F.
About Series 50. Series 50 is our heavy duty line, designed for challenging environments and loads up to 5,000 lb. These casters are engineered for towing operations, high shock and impact loads, maximum capacity at minimal mount height, and high capacity combined with floor protection.
