Wheel Selection Guide for Industrial Casters
How to specify caster wheels for your application
In general, the following points are true when selecting wheels:
The larger a wheel is, the easier it rolls.
The harder a wheel is, the easier it rolls.
The softer a wheel is, the easier it rolls
over rough surfaces.
Softer wheels are more resilient, but can develop flat spots if left in the
same parked position for a long period of time with a load greater than 50%
of the wheel's overall capacity.
A wheel's capacity increases with its width.
Soft tread wheels tend to carry less load
than hard tread wheels.
Caster wheel selection is sometimes art, sometimes science - and sometimes
it's contradictory when overlapping goals compete with each other. A wheel that
can withstand the temperature needed might not be ideal for the floor surface.
For instance, soft rubber tires protect the floor best, but can't cope with
flakes or debris on a work surface. Replacing soft iron with a poly wheel is a
good idea, but poly wheels may affect certain types of floor material. Each of
our wheels has a listed capacity, but that must be matched by the caster rig,
and of course by the cart or equipment the caster is mounted onto. Do not select wheels
strictly on the basis of capacity.
All wheels on this website are measured and charted based on the following

operations. It assumes clear floors without debris. For applications other than
normal factory or warehouse operating conditions, contact us. We're always glad
to help you with wheel selection questions.
