How to Choose Large Wheel Casters

Large wheel casters provide mobility and support for carts, racks, dollies and other equipment. They come in a variety of materials, wheel diameters, tread widths, load ratings and overall heights to suit many different kinds of work environments.

Wheel Materials

The material of a caster wheel influences the strength, rolling resistance, durability and noise level of the caster. Synthetic wheels made from solid elastomer, polypropylene or polyurethane, fiberglass reinforced polypropylene, and phenolic are a common choice for heavy-duty applications that require tough, long-lasting and hard-working equipment.

Everything You Need to Know About Large Wheel Casters: Benefits, Applications, and More

The ability of a caster wheel to roll easily is important for moving furniture and other equipment. If a caster isn’t rolling easily, the object or equipment may fall off the caster and cause damage or injury to those around it.


Casters’ size affects the amount of clearance that they allow. For example, if you’re installing the casters on an item with low-hanging ceilings, a smaller caster will allow more room between the caster and the top of the item.

Load Ratings

The load rating of a caster is the maximum weight it can hold at one time. The largest influence on the load rating of a caster is its wheel size, as wide wheels cover more ground surface area, so they accommodate heavier loads.

Brake Options

Industrial casters with brakes provide added safety and control when rolling the caster over a surface. These brakes can be installed on the caster’s side, or they can be attached directly to the caster’s hub. These brakes are simple and easy to use, as the operator simply presses a foot pedal on the side of the caster to lock and unlock it.
