Glass Filled Nylon Wheels

Glass-filled nylon wheels are rated for continuous operating temperatures up to approximately 300 degrees Fahrenheit. They can handle brief intermittent exposure slightly above that threshold, but sustained temperatures beyond 300 degrees may cause gradual softening. For environments above 300 degrees, consider high-temperature polymer wheels rated to 500 degrees.

Glass-filled nylon wheels typically support 15 to 30 percent higher load capacity than standard nylon wheels of the same diameter and width. The exact increase depends on the glass fiber content and the specific formulation, but the improvement is consistent across most sizes.

Glass-filled nylon is a hard tread material, so it does produce more rolling noise on concrete, tile, or steel floors compared to rubber or polyurethane wheels. In noise-sensitive environments, consider a polyurethane-treaded wheel instead, or accept the noise trade-off for the superior load and heat performance.

On sealed concrete or industrial flooring, glass-filled nylon wheels typically do not cause damage. However, on softer surfaces like vinyl, linoleum, or wood, the hard tread can leave marks or indentations under heavy loads. These wheels are best suited for industrial concrete, epoxy, or steel decking surfaces.
