Description
What is a Cone Crusher Head Assembly?
A cone crusher Head Assembly is the core working component driving the entire crushing process. Its primary critical function is to house the mantle, support the upper bowl geometry, and transmit massive crushing forces from the main shaft to the incoming ore. By combining heavy structural strength with precision rotational dynamics, a premium Head Assembly ensures consistent aggregate reduction, stable volumetric throughput (TPH), and protection against severe mechanical stress during high-tonnage mining and quarrying operations.
Equipment Compatibility & OEM Cross-Reference
Our aftermarket replacement Head Assembly components and individual sub-parts are precision-engineered to be direct-fit upgrades for Metso crushers, significantly lowering your Total Cost of Ownership (TCO) while ensuring zero compatibility issues and maximum field uptime.

What is Included in Head Assembly for Metso HP Cone Crusher?
A standard high-performance head assembly consists of 6 critical components working in perfect synergy:
- Head: The main structural heavy cast steel body that holds the mantle and transmits massive crushing forces.
- Head Ball: Forms the top spherical bearing surface, providing smooth gyration and reducing friction under heavy loads.
- Upper & Lower Head Bushings: Precision-machined bronze bushings that guide movement, reduce metal wear, and maintain alignment.
- Mantle: The high-manganese steel replaceable wear liner that directly contacts and crushes the rock.
- Pin: Made of hardened alloy steel to securely connect the head to the main shaft and transfer motion.
- T-Seal (Seal Ring): Flexible, heavy-duty seal that blocks dust entry and prevents lubricant contamination.
Core Engineering & Technical Advantages
Because the crushing head module is subjected to extreme compressive impacts, heavy friction, and high operational thermal stress, standard castings can quickly warp or fatigue. Our premium Head Assembly units are proudly manufactured in China to deliver unmatched heavy-duty durability:
Complete Drop-In Module: Every assembly integrates the main heavy cast steel head, precision head ball, upper/lower bushings, mantle, shaft pin, and durable T-seals, factory-matched and tested for immediate on-site installation.
High-Strength Cast Steel Body: Poured from premium structural cast steel to withstand massive mechanical stresses, preventing fatigue cracking and structural yielding under choke-feeding conditions.
Precision CNC Machining: Bearing journals, seating faces, and pin bores are machined to exact microscopic tolerances, ensuring a zero-vibration fit for internal bushings and wear liners.
Advanced Sealing Protection: Equipped with heavy-duty T-Seals that effectively block silica dust entry and prevent internal lubricant contamination during harsh quarry operations.
Maintenance Guidelines: When to Replace Your Head Assembly
Operating a crusher with a worn, cracked, or misaligned head assembly will severely disrupt the crushing chamber geometry and rapidly destroy adjacent components. We recommend thoroughly inspecting the Head Assembly components during major overhaul cycles:
| Inspection Focus | Warning Signs (Replace Immediately) | Best Practice Solution |
| Bursal & Bushing Wear | Excessive clearance or out-of-round deformation detected inside the upper and lower head bushing bores. | Replace the worn bushings or swap the complete assembly module to restore proper shaft alignment and prevent scoring. |
| Structural Metal Fatigue | Hairline cracks, deep gouges, or structural fracturing detected on the head casting or ball seating area. | Pull the damaged component immediately. Never attempt to weld load-bearing structural heads, as they will fail under crushing loads. |
| Seal Integrity & Seepage | Damaged, hardened, or torn T-Seals allowing abrasive rock dust into the internal bearing circuit. | Swap the damaged seals immediately and inspect the lubrication oil for fine particle contamination. |
