ESD castor for chair

Black Nylon Caster Wheels are reinforced with glass fiber to increase capacity and reduce friction when rolling.
These wheels weigh very little yet they have a load capacity comparable to most metal wheels.
They will not rust or develop a flat spot.
Nylon wheels are a better choice in wet and corrosive applications which require both chemical resistance and a higher load capacity.
We also use conductive nylon material,so it can use for ESD chair in EPA.
