  • Main and Secondary Load Bearing
(H52) Hardened and polished steel balls rotate in two heat treated raceways. (52HK) The raceway is CNC machined for precision swiveling to a finished size of 2 3/8” diameter then induction hardened to 45-50 Rockwell C for long wear with 3/8” hardened and polished steel balls.
  • Axle
1/2" diameter bolt with lock nut.
  • Lubrication Fittings
High temp grease rated to 750°F (In swivel assembly) and in wheels with roller bearings.

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.
