In this article, we will focus on our semi-pneumatic casters. We’ll provide a brief explanation of how they work to help you determine if they are right for you.
- What does semi-pneumatic mean? – The easiest way to explain what semi-pneumatic casters are and how they work is to contrast them with fully pneumatic casters. The word pneumatic refers to something containing or operated by a gas (such as air or nitrogen) under pressure. In other words, pneumatic casters use pneumatic wheels, which are essentially smaller car tires—they are filled with air to provide shock absorption. Semi-pneumatic wheels, on the other hand, have a thicker rubber skin and a smaller air pocket, which is not under pressure.
- How do semi-pneumatic casters work? – Unlike fully pneumatic casters, semi-pneumatic casters rely primarily on their thick rubber, rather than on an air cushion, to absorb shocks from uneven terrain. In addition, the air inside semi-pneumatic casters’ wheels is not under pressure, which means the wheel will not deflate if punctured. This makes semi-pneumatic casters a great choice for environments with sharp debris, as the casters will continue to function even if they happen to roll over a sharp object.
