Generally, the longer the diameter of industrial caster, the better barrier ability is.
Because industrial casters first form industrialization in the western countries in the late 19th century, the sizes of caster wheels generally are expressed in inches.
According to the specification of industrial casters, most of supermarket trolleys in China use 5 inches and 4 inches industrial casters.
Currently the sizes of popular industrial casters are from 1 inch to 10 inches and commonly sizes are 2 inches, 2.5 inches, 3 inches, 3.5 inches, 4 inches, 5 inches, 6 inches, 8 inches, and 10 inches. Use 4.6-inch industrial caster to make supermarket shopping cart, logistics cart and tool cars.
However, too long diameter of industrial caster will increase the gravity center of equipment, so it would be considered. If the equipment does not be often pulled, such as furniture, refrigerators and so on, using 3-inch industrial is OK.
