A swivel caster rotates a full 360° on its vertical axis, letting equipment turn and change direction without being lifted or dragged. It's the standard caster type for anything that needs to maneuver, typically paired with rigid casters on the same piece of equipment to keep it tracking straight.
The swivel section sits above the wheel fork and pivots freely around a central axis. On most carts and equipment, only two of the four casters are swivel — the other two are rigid — so the equipment can turn but still tracks predictably instead of wandering in every direction.
Swivel casters come in the same range of wheel materials, capacities, and mounts (plate or stem) as rigid casters — swivel vs. rigid is a separate spec from wheel type or capacity.
Anywhere equipment needs to turn in place or navigate tight corners and aisles — carts, dollies, mobile workstations, hospital equipment.
Using all four as swivel. Without a rigid pair, long equipment loses directional control and tends to wander or crab sideways under push.
Not checking swivel radius. The caster needs clearance to rotate under the equipment — a tight frame can bind a swivel caster mid-turn.

Should all 4 casters on a cart be swivel?
Usually no — most carts use 2 swivel and 2 rigid casters so the equipment can turn but still tracks straight under load.
What is swivel radius?
The distance from the caster's swivel centerline to its outer edge. It matters for clearance — too little room under the equipment and the caster can bind mid-turn.
Swivel vs. rigid — which do I need?
Most equipment uses both: swivel casters for maneuvering, rigid casters for straight-line tracking. Pure swivel-only setups are less common outside of chairs and light carts.
