What you’re describing is a twist-lock, bayonet-style foosball bearing set that’s common on Costco and other mass-market tables, where the outside half has three holes or slots that accept the metal trim ring which locks on with a short twist, and the angled plastic inside half just acts as a bushing and wood cover, so as long as your rods are standard 5/8" (16 mm) you can replace them with any 5/8" bayonet-mount foosball bearings (often sold as “tornado-style” or “twist-lock” bearings) and keep your existing metal covers, even if the table has no brand name.
