Thermoplastic Rubber (TPR) Casters by Type & Mount

Q: How do I choose between plate, threaded stem, grip ring, and expanding stem?

Choose by how your frame mounts the caster: plate bolts to a flat surface, threaded stem screws into an insert, grip ring press-fits into a socket, and expanding stem locks into tubular legs. For replacements, match your mount type and key dimensions first.

Q: When should I pick kingpinless TPR?

Choose kingpinless when impact, vibration, and rougher service shorten caster life. It’s used where durability matters more than lowest cost.

Q: Do you sell TPR wheels only?

Yes. Use the TPR Wheels Only section if you already have the caster frame and need replacement wheels by diameter/capacity.
