There are two types of castors – everything falls under one of these two categories:
Swivel castor: these castors can move in any direction, rotating 360°, even when under a heavy load. It’s this category that offers so many different options.
Rigid castor: unlike swivels, they cannot be steered. They only move in a straight line. Rigid castors are extremely durable, partly because they offer such limited movement. They’re rated as carrying the same load as swivels, yet a common perception among engineers is that they can carry heavier loads.
Focus on your application and ask yourself:
How much space will my application have to negotiate?
How often will I need to move the application and to where?
How much weight does my application need to move?
Over how far a distance will my application need to move? Want to find out which castor for which application? Read more here: www.essentracomponents.com/en-gb/news/guides/five-...
