Caster rollers are used to give equipment mobility in many kinds of workplace environments. From desk chairs in the office to gurneys that transport patient s, these small but vital parts of everyday furniture help improve productivity and efficiency.

Casters are affixed to the bottom of a larger object, such as a cart or dolly, which makes it easy for operators to move. They come in a wide range of materials, wheel diameters, tread widths and load ratings to fit specific applications.

There are two main types of casters: fixed and swivel. Each has its own advantages and disadvantages.

Swivel casters are usually better suited for moving loads that follow a 360 degree path, as opposed to the straight line of fixed casters. However, swivel casters can be less durable and may require special care.

They can also create a flutter at certain speeds, which can be annoying for users. It’s important to choose a caster with a long trailing distance, which helps prevent this problem.

Casters can be made from a variety of materials, including plastic, rubber and stainless steel. The best choice depends on the application, including the temperature and chemicals involved.
