Medium Heavy-Duty Casters

These medium heavy-duty casters fit plant carts, racks, and fixtures that outgrow light institutional casters but do not always need extreme Ultra Maxi Duty builds. Casters in this collection range from about 180 to 40,000 lb per caster. Everyday mid-band plant carts often land about 1,000 to 3,000 lb per caster on 4 to 8 in wheels. Wheel materials include polyurethane (poly or urethane), rubber, nylon, phenolic, iron, and forged steel. Soft polyurethane on aluminum (~85 Shore A) or TPR is the better pick when the floor has chips or debris. Most mounts are top plates. 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. Read the listing for the exact wheel size, overall height, and mount shown. Capacities below are per caster unless a listing says set. Lighter aisle: light duty casters. Heavier aisle: heavy duty casters.

Medium heavy-duty questions

Why is the max 40,000 on a medium page?

The assortment mixes mid-cart SKUs with some Hamilton UMD duals. Size from the listing you pick. Dedicated extra-heavy and extreme hubs own the 40,000 lb story.

Plate or stem?

Most titles here are plate mount. Stem options live on the stem hubs when the leg is a tube.
