A cart caster is simply a caster sized and specified for a rolling cart — the term describes the application, not a distinct construction. The right spec depends on the cart's load, floor, and how often it's moved.
Most carts use a mix of swivel and rigid casters, sized by total loaded weight divided across however many casters are used, with wheel material chosen for the floor and noise requirements.
Any cart-building or cart-replacement project — the starting point for figuring out the right caster spec.
Assuming “cart caster” is a specific product to search for. Start from load, floor, and swivel/rigid mix instead, using load per caster to size correctly.
