Rock Solid 4 Inch Cast Iron Caster Wheels 8 Pack Heavy Duty Industrial 5600 Lb Capacity With Precision Steel Bearings And Wide 2 Inch Treads Built Like A Tank For The Daily Grind

Industrial Grade 4 Inch Cast Iron Caster Wheels Replacement Set
✔️ 4 x 4 inch cast iron wheels with 2 inch tread and 5600 lb capacity

These caster units serve as robust mobility solutions for heavy industrial equipment, warehouse carts, and custom fabrication projects. Workers rely on them to transport dense machinery, chemical processing drums, and metal stock racks across concrete floors. The design handles demanding shifts while resisting heat and wear from harsh environments.

✅ 4 inch overall wheel diameter for smooth rolling action
✅ 2 inch tread width distributes weight evenly across hard surfaces
✅ 2-7/16 inch hub length aligns with standard axle mounting plates
✅ Heat resistant compound withstands temperatures up to 800F
✅ 3/4 inch steel roller bearing prevents friction during heavy loads
✅ Complete eight unit pack supplies replacements for large flatbed carts

💡 Why choose precision steel roller bearings over standard sliding bushings for heavy duty caster applications? Upgrading to sealed roller mechanisms significantly lowers rotational resistance when transporting extreme point loads across uneven shop floors. Hardened raceway coatings prevent metal fatigue during continuous lateral shifting, keeping axles aligned through thousands of moving cycles. Switching to this reliable rolling system gives your rigging equipment handy performance and stops frequent maintenance calls on busy production lines.
