| Cast polyurethane solid tread | About 80–95 Shore A | Very good abrasion resistance; suitable for frequent rolling on smooth industrial floors and moderate debris. | Approximately −30°C to +80°C, formulation dependent | High load capacity, low rolling resistance, quiet operation, and good resistance to oils and many chemicals. | Can be damaged by prolonged heat, steam, strong acids, or sharp floor obstacles. | Material-handling carts, warehouse equipment, conveyors, and indoor industrial trolleys. |
| Polyurethane tread on steel core | About 90–98 Shore A | Excellent resistance to chunking, abrasion, and tread deformation under high static loads. | Approximately −30°C to +80°C, depending on polyurethane grade | Combines a rigid load-bearing core with a resilient, floor-protective tread; long service life on hard floors. | Less suitable for very rough floors; high hardness may increase noise and vibration. | Heavy-duty carts, automated guided vehicle systems, industrial platforms, and production lines. |
| Thermoplastic polyurethane (TPU) | About 85–95 Shore A | Strong resistance to abrasion, tearing, and repeated flexing; performance varies significantly by TPU chemistry. | Approximately −20°C to +80°C for common grades | Good elasticity, low noise, clean appearance, and potential for thermoplastic processing and recycling. | May hydrolyze in hot, humid conditions when an unsuitable polyester-based grade is selected. | Medical carts, light industrial equipment, clean indoor environments, and precision transport systems. |
| Phenolic resin solid wheel | Typically Rockwell M 80–100 | Good wear resistance on smooth surfaces and strong resistance to many oils, solvents, and cleaning chemicals. | Approximately −40°C to +150°C, grade dependent | Handles elevated temperatures better than many elastomeric treads; relatively low rolling resistance. | Brittle under impact, noisy on hard floors, and unsuitable for uneven surfaces or sharp edges. | Ovens, bakeries, food-processing areas, hot industrial equipment, and chemical-handling environments. |
| Nylon / polyamide solid wheel | Typically Rockwell R 100–120 | Good abrasion resistance on smooth floors; resists gouging better than many softer rubber compounds. | Approximately −40°C to +80°C for common grades | Lightweight, non-marking, moisture resistant, and generally resistant to oils and many chemicals. | Hard tread can create noise; moisture absorption may affect dimensional stability and rolling performance. | Pallet trucks, food and pharmaceutical facilities, warehouse carts, and wet indoor areas. |
| Solid rubber / vulcanized rubber | About 65–85 Shore A | Good resistance to impact and surface irregularities; wear life depends on compound, floor condition, and load. | Approximately −30°C to +80°C for general-purpose compounds | Quiet running, excellent shock absorption, strong floor protection, and good traction. | Higher rolling resistance; may swell or degrade when exposed to oils, solvents, ozone, or excessive heat. | Indoor carts, hospital equipment, warehouse platforms, and applications requiring low noise. |
| Cast iron solid wheel | Typically about 180–300 HB | Very high resistance to compression and tread wear under heavy loads and moderate speeds. | Suitable for high-temperature environments; exact limit depends on bearings, grease, and wheel design | High load capacity, good dimensional stability, and strong resistance to heat and many industrial contaminants. | Heavy, noisy, prone to floor damage, and vulnerable to impact fracture or corrosion if unprotected. | Heavy machinery, foundries, steel plants, rail-guided equipment, and smooth concrete floors. |
| Forged or machined steel solid wheel | Typically about 180–350 HB; higher with heat treatment | Excellent resistance to heavy-load wear, rolling contact fatigue, and impact when correctly heat treated. | Suitable for high-temperature service; bearing and lubricant limits must be checked separately | Highest structural strength among common wheel materials; suitable for severe loads and demanding industrial duty. | High weight, high noise, possible corrosion, and substantial risk of damaging unprotected floors. | Heavy transport systems, rail transfer equipment, steel mills, shipyards, and outdoor industrial yards. |
| Stainless steel solid wheel | Typically about 150–300 HB, alloy dependent | Good wear resistance with superior corrosion resistance compared with ordinary carbon steel. | Suitable for elevated-temperature and washdown service within the selected alloy and bearing limits | Resists rust, frequent washing, and many corrosive environments; suitable for hygienic areas. | Higher cost and weight; hard tread may be noisy and can damage tiles, resin floors, or concrete. | Food processing, pharmaceutical plants, laboratories, marine environments, and clean washdown areas. |
