Where it fits. HeatEater is our high temperature wheel line, built on glass filled nylon so the wheel can run through oven and proofer cycles without softening, glazing, or flat-spotting the way a standard tread would. Glass filled nylon is a high-strength tread that carries heavy loads at low rolling resistance and shrugs off water and most chemicals. It will not rust or corrode. Nylon is among the hardest treads offered, so it is best matched to smooth floors where capacity outweighs quiet. 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 stainless steel for corrosion resistance. It mounts on a 3-1/8″ x 4-1/8″ top plate. A 3/8″ stainless steel dual precision bearing rides on a 5/16″ 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 -70°F to 550°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.
