Expanding Stem Casters 

Overall, expanding stem casters are a convenient and flexible solution for adding mobility to items with open tubing fixtures. They provide an alternative to traditional caster mounting methods and can be used in various settings where structural tubing is utilized.

Please note this is only a recommendation for a product we think will be your best option. It may not fit exactly what you are looking for so if you are unsure, please call us at: 800-501-3808 and you can speak with one of our excellent sales technicians.

Expanding Stem Casters are versatile and convenient solutions for mounting casters into open tubing fixtures.  Their primary features are the following:

  1. Design and Functionality: Expansion stem casters are specifically designed to mount casters into open tubing fixtures. They utilize a hex nut located beneath the lower raceway of the caster. Turning this hex nut expands the rubber adapter inside the round or square tubing, ensuring a secure and tight fit.
  2. Mounting Process: The caster is installed into structural tubing without the need for additional bolts or pins. Each caster features a knurled nut that is tightened to expand the rubber sleeve on the caster’s stem. This expansion allows the caster to firmly grip the inside of the tubing, holding it securely in place.
  3. Versatility: These casters come in various stem sizes, each with a specified range of tubing sizes that the stem can fit into. This versatility enables them to be used with a range of round tubes with different internal diameters.
  4. Applications: Expanding stem casters are suitable for a variety of applications. They can be mounted on carts, racks, stands, cabinets, and furniture that are constructed using structural tubing. By allowing these items to roll, they reduce the effort required for moving or repositioning.
  5. Installation: These casters are inserted into tubing, sockets, or drilled holes. They rely on friction to remain securely in place within the tubing.

You should never select on the basis of load capacity alone. There is no industry standard for load capacity ratings and they may not include a factor for abuse. Our capacity ratings are below what the casters are capable of carrying because most applications have less than perfect conditions. Please refer to the information shown at the bottom of this page. If you have any doubt as to which wheel or caster is the BEST choice for your application contact us for a recommendation.
