Stem Casters | Threaded, Grip Ring & Expanding Adapter

Stem casters are the right solution when a top plate mount isn't an option. They're ideal for equipment with a fixed mounting hole or a worn caster that needs a straightforward swap — no bolt pattern, no modifications.

AIE stocks stem casters in threaded stem, grip ring stem, and expanding adapter configurations across a wide range of wheel diameters, materials, and load capacities.

With over 55 years of experience and relationships with more than 35 manufacturers, our team can help you match the right stem type, size, and wheel material to your specific application — whether you need one replacement caster or a production quantity.
