Casters With Full Thermoplastic Wheels

Thermoplastic wheels have better impact resistance than phenolic wheeled casters, but they have poor resistance to higher temperatures. They are applicable in the food industry where high temperatures are not part of the environment.

Rubber-Wheeled Casters

An alternative to the phenolic wheel is the high-temperature rubber-wheeled caster. These wheels have a high-temperature thermoplastic center with a bonded high-temperature rubber tire. As with phenolic wheels, they will wear and may be damaged by poor or abrasive surfaces. They also have slightly lower load ratings than an equivalent diameter phenolic wheel because of their lower shear strength. A major drawback of rubber-wheeled casters is their poor resistance to acids, oils, chemicals and other substances harmful to rubber. These soft tread wheels, however, may ride more easily over bumps, level changes, joints, drainage gullies, etc., and are less destructive to tiled, linoleum, etc., floors. They also provide better shock absorption and traction.
