💡 What steps prevent premature wear on heavy duty cast iron caster wheels with polyurethane treads?

Swapping in solid cast iron hubs with poly tread is a handy upgrade that keeps utility carts moving steady under heavy pallet loads.
- Secure the half inch axle opening into matched brackets so the three quarter roller bearing spins free without wobble
- Sweep epoxy dust and metal shavings off the three inch wide poly tread every week to stop abrasion on the rubber compound
- Keep the hub length measuring two point four four inches clear of frame rails so turning radius stays tight indoors
