This hp crusher wear parts component is engineered for the adjustment assembly of the Metso HP300 cone crusher (compatible). Within the adjustment system, it helps transmit clamping and adjustment forces, maintain precise alignment between the adjustment ring and bowl, and isolate vibration—critical to keeping the closed-side setting (CSS) accurate, protecting threads and clamping interfaces, and ensuring long-term reliability in mining, aggregate, quarry, and recycling operations.
Supports the axial clamping force that locks the bowl/adjustment ring during operation
Maintains concentricity and alignment to prevent thread skew and uneven wear
Transmits low-speed torsional loads during CSS adjustments
Protects lubrication paths and sealing interfaces from dust and moisture ingress
42CrMo4 alloy steel, quenched and tempered
Typical yield strength ≥850 MPa; tensile strength 1,000–1,200 MPa
Hardness targeted for a balance of toughness and wear resistance
Precision-machined mating faces for the adjustment ring, clamping components, and locating pins
Critical interfaces held to ±0.02 mm; flatness ≤0.03 mm on reference faces
Surface finish Ra 0.8 μm on sliding/sealing and bearing-contact areas to minimize friction and wear
Engineered to withstand high axial clamping loads and the torsional inputs generated during setting adjustments
Validated through CAE/FEA to limit deflection and preserve thread engagement under peak loads
Direct replacement for ONA 7080500477 (adjustment assembly application) suit to Metso cone crusher
Compatible with Metso HP300 cone crusher adjustment system
Identical mounting patterns and interface dimensions for drop-in installation without modifications
Ribbed, CAE-optimized geometry distributes stress uniformly
Minimizes deflection that could cause thread misalignment or clamping loss
High-toughness material resists fatigue cracking in high-vibration environments
Ground reference faces and controlled concentricity to maintain CSS accuracy
Dowel/locator provisions for repeatable positioning and stable clamping
Tight tolerances reduce backlash during adjustment and stabilize operating conditions
Industrial epoxy primer plus polyurethane topcoat for long-term corrosion protection
Phosphate-treated fastener seating zones to reduce galling and fretting
Sealed grease/lubrication channels with O-rings to keep contaminants out and ensure consistent lubrication of adjustment interfaces
Pre-drilled and tapped holes with thread inserts for accurate alignment
Orientation marks and accessible fastening points reduce installation time
Service-friendly design for quick inspection and re-lubrication during routine maintenance
Maintains stable CSS and clamping integrity under 24/7 duty when processing iron ore, copper, gold, and other hard ores.
Supports precise secondary/tertiary settings for consistent gradation in concrete and asphalt aggregates.
Preserves adjustment thread health and clamping preload with abrasive limestone and granite.
Handles variable load conditions from concrete/asphalt debris while sustaining accurate setting and throughput.
By stabilizing alignment, clamping, and lubrication within the adjustment assembly, this component helps the HP300 operate at peak efficiency, minimizes thread wear and unplanned downtime, and maintains consistent product size over long service intervals.
