Cold Forged Caster Rigs

RWM 40, 46, 52, 53, and 54 series are manufactured from hot rolled pickled steel designated C1015. This steel has a higher tensile strength than the steel used in stamped casters. The cold forging process applies enough force to the parts to cause the molecules of metal to flow to points of greater strength. The cold forging process also refines the grain structure of the steel to produce deep smooth coined ballraces which do not require machining.

While cold forging hardens the raceway to a certain extent, it does not provide the same hardness as the case hardening process. To provide greater strength, therefore, RWM case hardens all raceways of our cold forged casters. This process provides longer wearing and easier swiveling casters.
