Medium-Heavy Stainless Plate Casters

These stainless steel casters stand up to washdown, moisture, and cleaning chemicals. Casters in this collection range from 300 to 1,250 lb per caster. Wheels in this category range from 4 up to 8 in in solid polyurethane, poly on aluminum, and more. Common uses include food processing, pharmaceutical, and wet plant areas. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Match plate size, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place, rigid casters for straight travel, and add a brake when the cart needs to stay put. Capacities below are per caster unless a listing says set. Confirm the load rating printed on the title before you order. Read the listing for the exact wheel size, overall height, and mount shown. Measure the old wheel or caster before you buy.
