A cone crusher bowl liner, also called the concave, is the fixed wear part that forms the outer wall of the crushing chamber. The mantle (moving cone liner) gyrates inside the bowl liner to crush the feed material through compressive force. Together, the bowl liner and mantle are the key wear parts that determine crushing efficiency, output gradation, and service life.”ife.
Because these liners take the heaviest impact and abrasion, choosing the right cone crusher liners is critical for performance, reduced downtime, and cost per ton.
PAJOA supplies a complete range of cone crusher bowl liners and mantles for Metso, Sandvik, Symons, Terex, and other global brands.
YOU can search by OEM part number to quickly locate the right crusher cone liner.
By integrating resources from more than 10 leading ISO-certified foundries across China, we ensure urgent needs are met and provide consistent, reliable alternatives to OEM parts — making PAJOA a trusted cone crusher liner supplier.
PAJOA supplies cone crusher bowl liners and mantles in a full range of manganese grades—Mn13Cr2 for softer or less abrasive rock, Mn18Cr2 as the balanced standard option, and Mn22Cr2 for hard and highly abrasive stone.
For extreme crushing conditions, we also provide reinforcement upgrades with TIC inserts and ceramic tungsten bars, delivering maximum durability and wear resistance under the toughest applications.
After more than ten years of field validation, our upgraded cone crusher liners have consistently proven to extend wear life by over 50% compared to OEM, helping operators reduce downtime and achieve lower cost per ton
Each crusher brand comes with its own OEM chamber profiles—such as EF (Extra Fine), F (Fine), MF (Medium Fine), M (Medium), C (Coarse), or EC (Extra Coarse)—designed for common crushing applications.
PAJOA supplies all of these cone crusher liners with accurate OEM fit, ensuring reliable performance across Symons®, Metso HP/GP/MP, and Sandvik crushers
When the OEM chamber no longer suits your site needs—whether due to premature wear, frequent blockages, or changes in feed material—our experts with over 30 years of experience can engineer a custom profile tailored to your conditions.
These custom chamber designs deliver longer liner wear life, less downtime, and better throughput & gradation control.
| Category | Options |
|---|---|
| Common Profiles | EF (Extra Fine), F (Fine), MF (Medium Fine), M (Medium), C (Coarse), EC (Extra Coarse) |
| Special GP Options | EC-LS (Extra Coarse – Long Stroke), EC-TR (Extra Coarse – Tertiary for GP220) |
| Series Coverage | Symons® (Standard & Short Head), Metso® HP, GP, MP Series, Lokotrack® / NW mobile crushers |
PAJOA partners with leading Chinese foundries and classifies cone crusher liners into three solution levels—Standard, Super, and Ultra—based on foundry capability.
This clear system allows you to select the right bowl liner and mantle without uncertainty, ensuring every order matches the required balance of cost, wear life, and performance.
Instead of guessing factory quality, you can rely on PAJOA’s sourcing network to deliver the right solution—whether it’s OEM-fit replacements, extended-life alloys, or reinforced liners with TIC and ceramic upgrades.
| Level | Source | Advantage |
|---|---|---|
| ★ Standard | Mid-tier OEM-fit foundries | Reliable concaves (bowl liners) & mantles with accurate OEM geometry |
| ★★ Super | Advanced foundries with stronger alloy control & heat-treatment lines | Extended wear life for abrasive feed and higher chamber pressure applications |
| ★★★ Ultra | Top-tier foundries with R&D capability (TIC inserts, ceramic bars, oversized castings) | Reinforced concaves & mantles, custom chamber profiles (EF/F/M/C/EC), up to 1.5× OEM wear life |
Manufacturing aligned with international and national quality standards.
Direct access to China’s top crusher parts factories for quality and supply reliability.
Custom-engineered parts for extreme durability and high-volume needs.
All crusher types, all major brands — spares and wears in one-stop sourcing convenience.
Yes. We validate against machine drawings, chamber codes, and perform dimensional checks (CMM/3D scans) to ensure safe fit and surface contact.
Our bowl liners are made with reinforced alloys (Mn22Cr2 with TIC or ceramic inserts) typically achieve 1.3–1.5× longer wear life under mining and aggregate conditions. Actual results may vary depending on geology, CSS, RPM, and feed consistency.
For standard profiles, delivery is typically 2–3 weeks. For custom cone crusher concaves and mantles, 4–6 weeks depending on complexity. We support trial orders and mixed containers, so you can start small and scale as needed.
We recommend evaluating them as a set. A worn mantle or liner will accelerate wear on the opposite part. PAJOA can advise the best bowl liner + mantle combination based on your chamber and gradation goals.
