    • Inferno Series Medium Duty Casters

    Inferno™ Series Medium Duty Casters

    Capacity Range: 360 – 960 lbs. Temperature Range: -22 – 750° F

    For standard high heat industrial applications, look no further than Hamilton’s new medium duty Inferno Series. These casters are zinc plated with the most popular mounting plate (4” x 4-1/2”) among industrial casters. This series features two different swivel constructions: the H52 models represents our standard duty rigs with high heat grease in the cold forged raceways. The H52 models are more cost effective compared to the more rugged 52HK models.

    The 52HK Models have a more durable kingpinless construction and are an excellent middle-ground value between the lowest cost H52 and our even tougher heavy duty high heat kingpinless.

    Unique dual-wheel models are also available featuring our new Ultratherm Wheel. Though pricey and limited to 4" diameter, these casters represent the highest rated high heat casters at 520 lbs. to provide both excellent floor protection and quiet operation. The dual wheel models are available in standard cold forged (H5242) or kingpinless (524HK2) swivel constructions.
