Balance extreme load capacity with total floor protection. Our HD Kingpinless Polyurethane on Iron Casters are engineered to carry up to 2,500 lbs per wheel while providing a non-marking, cushioned ride. These USA-made casters combine a rugged 1045 heat-treated steel kingpinless swivel with a heavy-duty cast iron core wheel wrapped in high-grade polyurethane, making them the ideal choice for automotive assembly lines, tow-line applications, and heavy material carts.

Advanced Industrial Performance:

• Floor-Safe Polyurethane: The high-performance polyurethane tread is chemically bonded to a cast iron core. It provides excellent floor protection, reduces noise, and resists debris rejection better than standard hard wheels.
• Legendary Kingpinless Raceway: By eliminating the kingpin, these casters remove the primary failure point found in lower-grade hardware. The precision-machined raceway ensures smooth swiveling under massive shock and impact loads.
• Tow-Line Ready: Specifically designed to handle the lateral forces of towed applications and AGV systems.
• AISI 1045 Steel Construction: Laser-cut and heat-treated steel legs are fully welded (inside and outside) for maximum structural integrity.

Product Specifications:

• Capacity: Up to 2,500 lbs (8" x 3") or 2,000 lbs (6" x 3").
• Mounting: Available with standard or 7.25" x 5.25" oversized top plates.
• Bearings: Precision sealed ball bearings for effortless rolling and long-term durability.

The Industrial Standard for Multi-Surface Protection. TACT Industrial’s Poly on Iron series is the workhorse of modern manufacturing.
