4 Position (-4SL) - convert swivel to rigid for straight line steering, robotically welded housing & CNC-milled slots assure long lasting, trouble-free performance.
  • Custom Engineering
Hamilton engineers will custom design any caster to meet customer requirements.
 
The new Inferno Series heavy duty series features Hamilton’s legendary forged steel kingpinless swivel construction with special high heat materials designed for autoclaves, product finish systems, and other extreme heat environments. The top plate and inner raceway are forged steel formed from one piece, providing incredible strength for shock conditions. All caster rigs in this series feature grease in the swivel raceways rated up to 750°F.

If floor protection is required, select the Thermolast™ wheel. For more rugged applications that don’t require floor protection, select the metal, stainless, or indestructible forged steel wheel types.

To minimize overall height, improve stability, and maximize capacity, Hamilton engineers have also designed a high heat dual wheel offering (see selection table at bottom). These low-riding high heat casters are built on the same proven and reliable ZFWH and ZFHS platforms.

For even higher load capacities, see our new MagmaMax™ Series.
