Clay wheel, clay pottery wheel, ceramics wheel and wheel pottery are all ways of asking about the same equipment. Suppliers list it simply as a pottery wheel, and the specifications worth comparing are the same whichever phrase brought you here.
The three specifications that matter
Stated centring capacity, which is how much clay the machine holds at speed under load. Wheel head diameter, which sets the largest bat and therefore the widest piece. And pedal control at low speed, because centring and trimming both happen slowly. Everything else on a listing is secondary to those three.
Why the wording varies
People come to this equipment from different directions: from clay, from ceramics as a subject, from having watched throwing. Suppliers use one term, buyers use several, and the mismatch means a search for a clay wheel can return anything from pottery equipment to industrial rollers. The trade word is wheel, or potter's wheel.
What a wheel is not
It is not a banding wheel, which is an unpowered turntable for decorating and hand building, and not a slab roller or an extruder, which shape clay by other means. Those are separate purchases with separate jobs, and a beginner buying a banding wheel expecting to throw on it is a real and recurring mistake.
Getting started with one
Sit at the right height, buy a bag of smooth or lightly grogged stoneware, and expect to reclaim most of what you throw for a while. The equipment beyond the wheel is genuinely minimal: a wire, a rib, a kidney, a needle tool, a sponge and a bucket.
Questions people ask about clay wheel

Is a banding wheel a pottery wheel?
No. A banding wheel is an unpowered turntable for decorating and hand building. You cannot throw on one.
What should I compare between machines?
Stated centring capacity, wheel head diameter and pedal control at low speed.
