Caster Concepts 81 Series Casters feature a kingpinless swivel section drop forged from C-1045 steel and a large, precision machined 4" diameter swivel raceway. The unique design of this swivel section actually places the 3/4" diameter load/thrust ball bearings in shear - effectively locking the swivel section together. These casters feature wheels up to 12" in diameter and load capacities up to 10,000 lbs.
Caster Concepts 81 Series Casters are suitable for power-towed applications, fiberglass/composite mold dollies, aircraft wing and spar tooling, engine and paint line dollies, chassis rack carts, aircraft maintenance stands and automated guided vehicles.
Northwest Caster offers Caster Concepts 81 Series Casters on a special order basis.
