Hamilton Cush-N-Aire Zinc Plated Casters 7100 Series – Heavy Duty

Capacity Range: 330 – 3700 lbs.

Hamilton 7100 Series Cush-N-Aire Casters deliver the same exceptional performance as the 7000 Series, with one key distinction: finish. While the 7000 Series features a durable HHA red crimson powder coat, the 7100 Series comes zinc-plated for enhanced corrosion resistance and a sleek, metallic appearance.

These shock-absorbing pneumatic casters are ideal for transporting sensitive loads such as missile components, electronics, ceramics, and liquids. They’re equally effective in rugged outdoor environments, where their pneumatic tires provide adjustable flotation—reduce tire pressure for added cushioning with lighter loads or inflate fully for maximum capacity and smoother rollability.

Rigid models match the swivels in both height and mounting template, and are built from heavy plate steel with legs welded inside and out to a reinforced steel top plate for superior strength and stability.
