W/ POLY ON ALUMINUM

Polyurethane on Aluminum Wheel Casters

Industrial swivel, rigid, and total-lock casters for corrosion-prone and washdown environments. Also referred to as poly-on-aluminum or urethane on aluminum casters.

Wheel Sizes:
4″, 5″, 6″, 8″

Configurations:
Swivel, Rigid, Total Lock

Capacity:
Up to 1,250 lb per caster

Mounting Plate:
4″ × 4-1/2″

Wheel:
Polyurethane on aluminum core

Yoke:
Zinc-plated steel (rust resistant)

Best Applications

Designed for applications requiring smooth rolling, corrosion resistance, and high load capacity without floor marking.

Common industrial uses

Food processing and washdown equipment
Laboratory and pharmaceutical carts
Hospitals and institutional material handling
Bakeries and food service equipment
OEM and industrial production carts

When to choose a different caster

Severe shock or impact loading
Continuous exposure to aggressive chemicals
Applications requiring full stainless construction

Materials & Corrosion Resistance

Aluminum wheel cores provide inherent corrosion resistance and strength. Polyurethane treads are non-marking and roll more easily than rubber. The caster yoke is zinc plated for rust resistance in typical industrial environments.

Zinc plating improves corrosion resistance but is not equivalent to stainless steel in harsh chemical or continuous washdown conditions.

Need Full Stainless Steel Casters?

For aggressive washdown, corrosive chemicals, or stainless-specified applications, use our 304 stainless steel caster series.
