We supply high-performance cone crusher liners — including bowl liners, also called mantlesy concavidades — built to match your machine and working conditions. From standard replacements to custom chamber profiles and material. PAJOA helps you find the cone wear parts that fit and last.
En PAJOA, we go beyond basic supply. We help you find the crusher cone liners that actually perform under your site's conditions.
Whether you need just the manto, the concave, or the full wear set, we deliver matched solutions — based not only on your crusher model but on your working material, feed sizey chamber pressure.
Matching chamber profiles is not guesswork. Whether you're working with a Symons short head, a Metso HP300 Coarse, or a Sandvik CH440 Medium, we can replicate the original geometry down to the detail — or fine-tune it for your current throughput needs.
We know which Chinese foundries specialize in which alloys and profiles, helping you avoid guesswork. And we’re ready to supply liners that don’t just fit — they outperform. Know more about outstanding partners in China.
Most cone crusher liners start with manganese steel: Mn13Cr2 or Mn18Cr2. For tougher jobs, Mn22Cr2 or TIC-insert liners bring extra strength. In silica-heavy or abrasive stone, our ceramic-reinforced options help extend liner life and reduce changeouts.
Each liner — whether bowl liner, manto, or concave — can be cast up to 14 toneladas, supporting even the largest crushing operations.
And based on real-world feedback, our reinforced mantles and concaves have reached up to 1.5× the wear life of previously used parts.

En bowl liner, however, is the replaceable wear part mounted inside the bowl that works with the mantle to crush material.
