Caster City, Inc. 4" x 2" Ductile Steel Wheel - 3/4" Roller Bearing DS4x2

4" Diameter 1200 lbs. Capacity Where loads are too heavy for floor protective wheels, or where unusually severe service factors are present, forged steel & Ductile steel caster wheels will do the job. Usually in these applications the user will not consider floor wear as too great a penalty considering the work that is being done. Forged steel caster wheels will damage most factory floors, and thus are generally used on steel plate, in channel, or as V-groove wheels rolling on angle iron track. Forged steel & Ductile steel caster wheels have high ductility and tensile strength, and thus can absorb shock or impact without failure. These solid (spokeless) wheels are unbreakable in normal service. Their load ratings are limited by bearing capacity only. These steel wheels are capable of temperatures up to 700° F depending upon the application. At temperatures above 400° F continuous, steel roller bearings and spanner bushings can start to anneal. In applications where temperatures are above 400° F, please consult our engineering dept. at
