Hamilton ZFSEC Spinfity Endurance Casters

Capacity range 2200 to 6,000 pounds

Spinfinity Super Endurance Caster Series (ZFSEC) replacing Hamilton's legacy SEC Series, represents the "best of breed" kingpinless design for extra heavy-duty applications. Like its predecessor, the swivel top plate and inner raceway are each made from forged steel, providing superior strength for shock conditions.

The ZFSEC features a new heavy-duty "V-Style" seal that offers superior protection against dirt, debris, and moisture, ensuring longer life and consistent performance in the toughest environments. Heavy-duty precision ball bearings are in all wheels. So now combined with the new swivel assembly, all ZFSEC casters are zero-fix, or 100% maintenance-free, helping customers reduce maintenance costs and downtime. In this enhanced series, zerk fittings have been removed and are no longer needed.

  • Swivel Construction: Forged steel top plate and fork base; 3/8" x 3" plate steel legs welded inside and out to forged steel horn base.
  • Load Bearing: 3-5/8" diameter hardened and CNC-machined raceway with 5/8" balls.
