Match a 2-3/8 x 3-5/8 top plate when bolting casters under bake carts, metalworking fixtures, and debris-heavy floors. Typical builds show wheel diameters 3 to 12 in and polyurethane, phenolic, and nylon treads. Replace worn corners in matched sets when possible so the cart tracks straight under load. Harder poly rolls easier on smooth epoxy; softer poly cushions vibration on uneven slabs. These medium-duty options cover everyday bake carts, metalworking fixtures, and debris-heavy floors without jumping to extreme forged series.

Caster Catalog by Load Capacity & Mount Type: buying guide

CasterHQ organizes the full 1,204-caster catalog the way procurement teams actually buy: by capacity tier first, then by mount type, wheel material, brand, or application. Start with the load per caster you need (cart weight divided by 4, plus a 25-30% safety margin) and pick the tier below. From there the page filters narrow to plate or stem mount, swivel/rigid/brake, and wheel material. Sirius HD is our house brand series in the heaviest poly-on-aluminum tier; Hamilton, Albion, Faultless, and Caster Concepts cover the broader catalog.
