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. Thread guards are fitted to keep string, film, and debris out of the axle. This model is supplied with a directional lock brake. A 3/8″ steel dual precision bearing rides on a 3/8″ axle for smooth, low-effort rolling.
Load and duty. The 200 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 600 lb cart with margin for shock loading and uneven floors. Continuous operating range is -30°F to 140°F.
About Series 26. Series 26 is our medium duty industrial caster line, offered in both swivel and rigid plate models. It is built to a higher mount height than the rest of the 20 Series, which makes it a straightforward replacement caster across a wide range of existing equipment. Capacities run from 180 lb to 425 lb per caster, with a choice of three plate sizes and four brake options.
