Industry-Standard 2″ Wide S304 Stainless Steel Casters
Medium to Heavy Duty • Up to 1,250 lb Capacity


This industry-standard 2″ wide stainless caster series is engineered for medium to heavy duty industrial applications requiring corrosion resistance, structural reliability, and predictable rolling performance. Manufactured from S304 stainless steel, these casters are designed for washdown, food processing, pharmaceutical, marine, chemical, and industrial environments where carbon steel fails.

Available in 4×2, 5×2, 6×2, and 8×2 wheel sizes with a 4″×4-1/2″ stainless top plate, this series supports both swivel and rigid configurations and is rated for loads up to 1,250 lbs per caster, depending on wheel material and diameter.

Core Specifications

  • Frame Material: S304 stainless steel (yoke, top plate, fasteners)
  • Wheel Tread Width: 2 inches (industry standard)
  • Wheel Diameters: 4″, 5″, 6″, 8″
  • Mounting Plate: 4″ × 4-1/2″ stainless top plate
  • Configurations: Swivel or rigid
  • Capacity: Up to 1,250 lbs per caster (application dependent)

Wheel Material Options

To optimize performance across different floors and environments, this stainless caster series supports multiple industrial wheel materials:

  • Polyurethane: Quiet rolling, floor protection, high load capacity
  • Nylon: High chemical resistance, low rolling resistance
  • Polyolefin: Economical, corrosion resistant, non-marking
  • Phenolic: Extreme load handling, heat and impact resistant
  • Additional compounds: Available for specialized OEM requirements

Typical Applications

  • Food processing and washdown equipment
  • Pharmaceutical and cleanroom carts
  • Marine and coastal industrial equipment
  • Chemical processing facilities
  • Material handling carts and racks
  • OEM stainless equipment builds

Engineering & Compliance Notes

S304 stainless steel offers excellent corrosion resistance for most industrial and sanitary environments. Load ratings are based on controlled rolling conditions with properly distributed loads. For high-impact, shock loading, or continuous duty cycles, consult engineering guidelines when selecting wheel material and diameter.

Frequently Asked Questions

What does S304 stainless steel mean?

S304 stainless steel is an austenitic stainless alloy known for corrosion resistance, durability, and suitability for washdown and sanitary environments.

Are these true industrial stainless casters?

Yes. This series uses stainless steel frames, mounting plates, and hardware, designed specifically for industrial duty applications.

What is the difference between 4×2 and 8×2 stainless casters?

Larger diameters roll easier over debris and support higher loads, while smaller diameters reduce overall equipment height.

Do these casters work in washdown environments?

Yes. S304 stainless construction is commonly used in washdown, food processing, and sanitary environments.

What load rating should I select?

Divide total equipment weight by the number of casters, then apply a safety factor for dynamic loading.

Are swivel and rigid versions available?

Yes. This series is offered in both swivel and rigid configurations.

What floor types are compatible?

Concrete, epoxy, tile, and sealed industrial floors depending on wheel material selection.

Do these meet food-grade requirements?

S304 stainless is commonly used in food and pharmaceutical equipment. Always verify regulatory requirements for your application.

Are custom wheel compounds available?

Yes. OEM and bulk configurations may support additional wheel materials.

What mounting plate size do these use?

This series uses a standardized 4″×4-1/2″ stainless steel top plate.

How long do stainless casters last?

Service life depends on load, environment, and duty cycle, but stainless casters typically outlast carbon steel in corrosive conditions.
