FAQs About Casters

Casters are a very handy device that has one or more wheels and makes it easy to move large or heavy loads. They can be found everywhere from mop buckets to warehouses. There are casters for furniture and shopping carts as well as pallet jack wheels and trash bin caster wheels. Here are some frequently asked questions about casters.

What are casters made of? Casters can be made of many different materials like wood, glass, aluminum, steel, iron, rubber, polyurethane, or nylon. The type will depend on the weight of the load, the condition of the floor, the environment, and the type of load.

How do I choose the right caster? You first need to consider the weight of the load and the type of floor you have. Also decide how easy you want the load to roll and the climate. High heat, moisture, excessive dust, and chemicals can damage casters.

Can certain casters withstand high temperatures? Yes, it depends on the wheel materials. Here are some examples:

·         Polyurethane - 130 degrees F

·         Phenolic ( Fiberglass ) - 300 degrees F

·         Glass Filled Nylon - 475 degrees F

·         Forged Steel and Cast Iron - 800 degrees F

How do I determine the weight of the load? You have to remember to add the weight of the load to the weight of the cart or container. Divide that number by three to get the minimum for each caster. Do this even if you will have four casters because on an uneven floor, three casters may carry all the weight for a short time.

Why do some loads make casters shake or flutter? The shaking is caused because only three wheels are carrying the load. That leaves one to rotate independently until the load shifts to that one plus two others. The lead in the caster would need to be lengthened to stop the flutter.

How do I compensate for rough floors? You can use a larger wheel or pick a different material, such as rubber or polyurethane.
