316 Stainless Steel Rigid Caster – 4″ Solid Polyurethane Wheel

Description

This solid all polyurethane industrial caster wheel was developed for sanitary and washdown applications, and is capable of rolling indoors or outdoors. The blue all polyurethane (“AP”) caster wheel is manufactured in 1-¼” and 2” wide; with diameters ranging from 3”-5” and 4”-8”. Caster City manufactures this (“AP”) blue all polyurethane wheel to come with a roller bearing, delrin bearings, or a sealed precision ball bearing and all bearing options are available in stainless steel as well. The temperature range of this industrial caster wheel is -50°to 180° F and the durometer of the polyurethane is Shore 60D.

These wheels are non marking and non conductive. The absence of a metal center eliminates bond failure as a cause for wheel replacement. These caster wheels are especially suited for use with stainless steel casters in wet and corrosive applications. They are designed for use in Pharmaceutical Laboratories, Hospitals, and Food Processing Plants – wherever a clean sanitary design is desired. These wheels are not recommended for applications involving shock, overloading, abuse, obstructions, poor floors, or for storage (standing) loads. Hardness is 60 – 65 Durometer Shore D. Temperature range is -20° to 180° F.

These wheels are designed for use in a wet environment and they eliminate the possibility of tire separation.

316 Stainless Steel Vs. 304 Stainless Steel

In industrial and engineering applications, the choice between 316 and 304 stainless steel is driven by environmental exposure and corrosion resistance requirements. 316 stainless steel, enhanced with molybdenum (2-3%) and a higher nickel content, provides superior resistance to chlorides and harsh chemicals compared to 304 stainless. This makes it essential for marine environments, chemical processing facilities, and applications involving aggressive cleaning agents or high salt concentrations.

The addition of molybdenum in 316 stainless significantly improves resistance to pitting and crevice corrosion, particularly critical in environments where chloride exposure is constant. This grade is widely specified in marine installations, chemical plants, food processing facilities, and pharmaceutical manufacturing where regular exposure to caustic cleaning agents and process chemicals would compromise 304 stainless steel’s integrity.

While 316 stainless steel commands a higher price point than 304, its enhanced corrosion resistance makes it the optimal choice for applications where equipment failure due to corrosion cannot be tolerated.

316 Stainless Steel Industrial Casters Model 3. Capacity up to 300 pounds per caster. 316 stainless steel casters excel in highly corrosive environments such as marine applications, chemical processing plants, pharmaceutical manufacturing, food processing facilities (especially those using caustic cleaners or salt), water treatment facilities, and any setting where exposure to chlorides, acids, or harsh cleaning agents is routine.
