Mantle, bowl liner and concave castings for Symons 2FT, 3FT, 4FT, 4.25FT, 5.5FT and 7FT cone crushers.
Six sizes: 2FT, 3FT, 4FT, 4.25FT, 5.5FT and 7FT. This is the oldest cone family still in daily service in a lot of plants, and the parts are the most widely copied in the industry, which is exactly why the fit is inconsistent between suppliers.
The number is the head diameter. It is not the specification.
Every size above 2FT was built in both a standard and a short head configuration, and the bowl and mantle differ between them. A 4.25FT bowl liner quoted without knowing which one is running will be wrong about half the time. We ask for the old liner or the bowl photograph, and we will not guess from the number alone, because guessing here produces a casting that seats and then does not crush.
It sits between the 4FT and the 5.5FT and shares nothing with either. In our experience it is the size where an enquiry most often carries the wrong number, usually because someone read a parts book printed for a different machine. We measure the bowl and confirm the size before quoting rather than accept the number as given.
A lot of these frames are decades old and have been rebuilt more than once. If the bowl has been replaced by a previous supplier, the geometry in the machine may not match the original drawing. Send the worn part where you can. Where you cannot, we say which dimension we are relying on so that the risk is visible before the pour, not after.

2FT, 3FT, 4FT, 4.25FT, 5.5FT and 7FT, with mantle and bowl liner listed for each in the table above.
Yes, and we would rather confirm it than assume. Send the marking from the old liner or a photograph of the bowl and we will quote against that.
Yes. They are listed with the cone parts for each size, though on some sizes they are machined rather than cast.
