Phenolic caster wheels are molded under high pressure and temperature. Their hardness is comparable to traditional iron wheels
Phenolic caster wheels will wear well on concrete, and are the wheel of choice for pallet jacks. Heavy standing loads will not deform these casters. These caster wheels are highly resistant to oil, grease, gasoline, and mild acids. Temperature range is -40° to +250°F
When purchasing casters with a workbench, the casters will not affect the work surface height you selected. The legs will be cut shorter to produce the work surface height you have specified.
