A dual-wheel caster uses two wheels side by side on one axle instead of one, spreading the load across twice the contact area for higher capacity or added stability in the same footprint as a single-wheel caster.
Dual-wheel construction is common on heavier-capacity models where a single wheel of practical size wouldn’t provide enough load-bearing surface, and it can also add rolling stability on uneven surfaces.
Higher-capacity applications wanting more load-bearing surface without moving to a much larger single wheel.
Assuming dual-wheel automatically doubles capacity. It increases capacity and stability, but the rated number is still specific to the model — check the actual spec rather than assuming a simple 2x multiplier.

Does dual-wheel mean twice the capacity of single-wheel?
Not necessarily a clean 2x — check the specific model's rated capacity rather than assuming a simple multiplier.
Is dual-wheel more stable than single-wheel?
Often yes, particularly on uneven surfaces, due to the wider footprint.
