You toss dead weight rollers with these handy four pack caster sets to fix rattly tool carts or stiff office chairs. The red polyurethane tires grip clean without marring wood floors. You bolt them down fast using standard three eighth inch by nine millimeter threaded stems. They pivot full circle so you roll heavy gear around tight garage aisles without burning out your shoulders.

✅ Double ball bearings handle up to 440 lbs per wheel without wobbling
✅ Six point inch by 155 millimeter overall height fits standard slots
✅ Three eighth inch by nine millimeter stems screw tight into place
✅ Smooth red plastic tires glide quietly over concrete or gym floors

💡 Why should you pick sealed swivel caster assemblies over basic plastic rollers for moving heavy loads?
Basic setups fall apart fast when you hit rough warehouse flooring regularly.
- Toughest bearing cores cut rolling friction for slick directional changes anywhere
- Thick polymer tires absorb impact shocks so your inventory stays perfectly locked
- Threaded mounting kits fit most industrial frames without needing extra adapters
- Heat resistant materials keep grip tight even after running hot summer shops late
