Swivel casters exhibit various resistances depending on the surface on which they are used. For example, tile surfaces and carpets exhibit less swiveling resistance. As such, carpet surfaces should be avoided when maneuvering an MWC. The curvature radius of the wheel trajectory also significantly affects the swivel resistance, though this decrease is not linear.

Dimensions

Swivel casters have different starting and rolling resistances. The lower the starting resistance, the easier the cart will move. Larger swivel wheels and harder materials are better at reducing resistance. Dimensions should be kept in mind when selecting a caster for your application. 

Determine the weight of the object you will be moving with the caster. To determine this, measure the object’s weight to be moved, including the cart and any additional loads. Next, multiply this total weight by the number of casters you require minus one. It will build a buffer zone for capacity. …
