Casters are wheels that are attached to items like furniture, carts and pretty much anything else that is wanted to be moved. As such, casters have many applications, both for home use as well as in production of other goods. Home owners may be interested in casters that are easily attached to furniture and cabinets, allowing easy moveability. For factory production, wholesale or industrial casters are typically called for.

There are a wide variety of companies that supply casters of all types, and then have easy online access, allowing you quickly browse their selection as well as pricing. Most online caster suppliers have segmented their casters by use as well, allowing you to find casters to fit specific needs and sizes. Like most online suppliers, caster vendors allow the shopper to easily find the right caster at the right price, as well as determine possible wholesale pricing for large caster orders.

When looking for casters to fit your need, be sure to consider the following:

- What type of caster do you need? Typical choices include Stem and Plate mounting options.
- What size caster do you need?
- What caster material is the right choice? How demanding is the application? Is a heavy duty caster needed?
- What types of volume discounts might the caster supplier offer (if applicable)?
- Does the caster need to be able to swivel to allow more flexible maneuverability?
