A dolly caster is sized for hand-pushed dollies moving heavy, often palletized loads over short distances — typically higher capacity per caster than a general cart, given the concentrated weight dollies often carry.
Because dollies are often loaded to near their rated capacity regularly, bearing quality and wheel durability matter more here than on lighter, less-frequently-maxed-out carts.
Moving heavy, dense loads — machinery, appliances, palletized goods — over short warehouse or shop-floor distances.
Undersizing capacity for a dolly’s typical near-max loading pattern. Build in more safety margin than you might for a cart that’s rarely loaded to its limit.

What capacity should dolly casters have?
Size generously above your typical load, since dollies are often loaded near their rated maximum more consistently than general carts.
Do dolly casters need to swivel?
Often a mix, similar to carts — rigid for straight-line stability, swivel for maneuvering in tight spaces.
