About Casters and Wheels

Cart-King Casters with Polypropylene Wheels

Rigid

Swivel

Swivel with Total Lock

Our most popular casters for carts and dollies, these casters have lightweight polypropylene wheels that roll well on smooth surfaces.
Wheels have sleeve bearings to prevent wear to the wheel bore, but these don't roll as easily as other bearings.
Swivel casters have double-ball bearings for the smoothest swiveling.
Casters with total lock brake the wheel and lock the swivel with one press of the foot pedal.
