Industrial Caster Sockets
Also known as caster inserts, caster sockets keep your furniture quiet while absorbing force. They are designed to install into a hole in mild (carbon) steel. The tube end can be round, square, rectangular, or oval and attaches to a caster typically via a caster stem.

Steel Caster Sockets
Steel caster inserts typically consist of a zinc-plated steel platform and two heat-treated spring steel retaining clips. To meet the needs of any job site or facility, we stock parts to match both English and Metric thread sizes. Our extensive inventory of in-stock metal caster sockets includes components to fit in 7/8” to 2”+ OD tube and from 10 to 20—gauge tube.
For threaded steel caster sockets, please see steel threaded adaptors.
Plastic Caster Sockets
Typically made of nylon, HDPE, or other plastics, plastic caster inserts are injection-molded one-piece components designed to press fit into a hole. Plastic caster sockets will fit in 7/16” and 9/16” round holes, with tubing from 13/16” to 1-1/4”+ OD friction ring stem or 5/16” grip neck stem. While threaded plastic caster inserts do not have the load-bearing capacity of metal caster sockets, they are the more cost-effective option.
Twin Wheel Caster Inserts
Made with a hard plastic body with either hard plastic wheels or soft urethane wheels, twin wheel caster sockets are an ideal solution for heavy-use furniture such as hospital beds, display stands, trolleys, or operating tables. Various OD wheels are available, including 37mm, 40mm, 42mm, 45mm, 55mm, 75mm, and 100mm.
Single Wheel Caster Inserts
Single wheel caster sockets come in a huge selection with many options available. Sizes range from 1” to 10” with wheels manufactured from hard plastic, hard rubber, soft rubber, and polyurethane. Various load ratings, styles, stems, and other configurations are available.
How to Choose the Best Round Caster Socket
When selecting a caster socket for your tube, there is no one-size-fits-all answer. By considering a few questions and the requirements of your application, you can determine which model or material is best suited to your needs:
- What are your load requirements?
- Do you need to plate mount or insert your casters?
- What size wheels does your furniture or components require?
- Which stem configuration is best for your planned use?
