characteristics of many caster wheel materials.

This chart describes the characteristics of many caster wheel materials.

Wheel Material	Characteristics
Cast iron	High-capacity and abrasion-resistant for easy rolling and long service life on concrete. High-temperature options available.
Ductile iron	Superior resistance to breakage, cracking and chipping for long service life in the most severe applications.
Forged steel	Nearly indestructible in normal applications and long service life. Used where floor protection is a secondary consideration, or for use on steel plates.
Glass-filled nylon	Will not chip, absorb water or break down in caustic environments. High-temperature options available.
Monoprene	Rejects debris while offering the same great features as a pneumatic wheel without going flat.
Neoprene	High resistance from oil and chemicals while providing sufficient cushioning to substantially lower or eliminate shock, vibration and noise levels.
Nylon	Withstands solvents, corrosive environments and temperature extremes.
Phenolic	Floor protective and highly resistant to oil, grease, gasoline and mild acids. Recommended for use on smooth concrete. NR for wet applications or use over rough surfaces. High-temperature options available.
Polyolefin	Lightweight, one-piece solid sanitary design suited for use in wet and corrosive applications.
Polypropylene	Resists absorption and withstands most chemicals and solvents.
Polyurethane	Easy-rolling wheels cushion loads, protect floors and offer superior chemical resistance.
Rubber	Long-wearing wheels provide floor protection and quiet operation. Includes pneumatic, semipneumatic and flat-free options.
Stainless steel	Strong and durable design. Ideal for use in wet, corrosive or sanitary environments.
Steel	Provides strength and shock resistance with long service life and economy for use in rough service conditions.
Thermoplastic rubber (TPR)	Chemical- and water-resistant. Absorbs shock and protects floors while providing easy rollability. High-temperature options available.
Vulkollan	Highest quality polyurethane. Extremely durable with excellent abrasion resistance. Easy to roll
