What Are Expanding Stem Casters and Installation

Expanding stem casters are the perfect answer for adapting tables and equipment with tube legs into an easy rolling object. The adapting rubber stem can easily install into either round or square tubing.

Whether you are a do-it-yourselfer, commercial kitchen, or a major manufacturing facility, Service Caster has an option for you. With 10 sizes ranging from 3/4" to 1-7/8 in both zinc plated and stainless steel, we are sure to have a caster to meet the needs of your application. Wheel options that match your usage and flooring are available from soft rubber to hard rubber, and non marking, non flattening polyurethane.


How to Install Expanding Stem Casters

In its simplest terms: tighten the topmost ring on the expanding caster adapter stem before insertion to compress rubber until it fits snugly into round or square tubing. It may be necessary to further tighten the nut under the swivel with a wrench until adequately secured. For further details, please check out the video.


In addition to phone calls, specs and images can be emailed to us, and physical samples can go a long way to making sure you get exactly what you need. Service Caster also has the ability to custom engineer and produce the exact caster you require.
