Expandable Adapter Stem Casters

The expandable adapter stem casters are used to support carts used in the food service and medical industries as well as many others. The expandable adapter on these casters allows a user to enjoy the smooth, controlled movement of a cart's wheels. Items can be moved to different locations with a minimal amount of effort from the user. Our expanding stem casters can support various pieces of laboratory equipment, racks, retail displays and more. They are able to support items of light to medium weight. These caster stem types are available with top or face brakes. There are also a number expandable stem adapter options available. These unique casters are corrosion resistant and made of quality materials that help them to endure the wear and tear that comes with everyday use.

An expandable adapter stem is installed into tubing beginning in either the lower nut under the raceway or the racing itself. As the rubber piece of the adapter begins to grip the inside of the tube, the fastener will tighten down on the rubber piece and expand it to securely hold the caster in place. The stem should be tightened to ensure there is no movement or possibility of the caster stem coming loose. While round adapters can fit in square tubing, you may need to use the next size up to find proper fit and grip. Click here for sizing and measuring tips .

All casters in this section have option to add a brake, to turn these standard casters into Locking Casters.
