Wheels Steel & Ductile Ductile Steel
FeaturesKnown as ductile steel or ductile iron wheels, these forged steel wheels are of extremely strong, heavy core and wheel face. When loads are too heavy for floor protective wheels, ductile steel wheels will do the job. Forged steel wheels, especially under intensive loads, can damage concrete floors, and thus are generally used on steel plate, channel, or as V-groove wheels on angle iron track. Ductile steel wheels are the highest capacity option up to 8000 Lbs (3630 Kg) on relatively even and smooth surfaces. Available wheel diameters range from 4" to 12", and tread widths of 2" to 3". Able to withstand temperature extremes and high impacts. Use only where floor protection and noise concern are not major factors. Offers effortless tolling under heavy loads. Not recommended for towing, or fragile loads on rough floors.

Bearing OptionsNote: Listing limited to most popular. Go to: Parts & Accessories / Bearings Plain BoreInner diameter of the caster wheel's hub centerbore. No bearing or components inserted, unless specified.
DelrinPreferred for use where water or liquids are present. Delrin bearings are corrosion resistant, and effective in a wide temperature range.
AnnularOur annular radial ball bearings are a 1-pc bearing. For light-duty applications, higher stability than a single precision bearing. 3x's the surface contact with the axle , and caster legs can be tightened against the extended bushing.
RollerStandard anti-friction bearings for manual applications. Performs well under shock loading (perpindicular force), for light to super heavy duty applications. Not suitable where side thrusts are common.
PrecisionRadial precision ball bearings are maintenance free and provide superior rollability for manual applications. One pair per caster wheel, one is press fitted in each side of the hub. Perfect for light to heavy duty applications, but not where shock loading is common.
Tapered RollerThe ultimate bearing for super heavy duty and power-towed applications. The same type of bearing used for automobiles, that endures where side thrust and higher speeds are prevalent.
