One question we get a lot here at SCC is “Why choose a twin wheel caster instead of a single wheel caster?” Well, let me tell you.
A twin wheel caster offers several distinct advantages over its single wheeled counterpart. Perhaps the most obvious advantage is weight handling capacity. If we take two casters with the same wheel diameter and material, but one is twin wheeled, it will handle more weight. Another way to look at this advantage is that we can use a smaller twin wheel caster to reach the same weight bearing capacity as a larger single wheel. This can be important if you need to maintain a lower load height within a specific weight capacity range.
Another great advantage of twin wheel casters is their ability to turn easily. Where a single wheel caster must pivot on itself, a twin wheel caster’s wheels can rotate independently of each other, making turning or reversing direction much easier.
