PHENOLIC

Made of phenolic resin and macerated canvas, phenolic wheels are are a common commodity-choice intended primarily for push/pull applications. Phenolic wheels are hard, and make movement easier, while resisting oil and other chemicals.

The benefits of phenolics include:

• Economically priced
• Resistant to extreme temperatures
• High weight capacities
• Resistant to oils, greases and some liquids

These wheels are recommended for hard flooring , but are not recommended for wet environments*, or for areas where lots of debris is present. Not recommended for towing at high speeds or for use on poor floors.

*When a phenolic caster wheel becomes chipped on impact and gets exposed to moisture, it becomes a sponge. The shape of the phenolic caster wheel will expand and deform, rendering the caster wheel ineffective.
