Identify parts for Metso cone crushers, check models and drawing, confirm materials and processes, and submit an inquiry.
Equipment and Applicable Models
Identify the installed machine model and key dimensions, then check the drawing revision and physical interfaces.
Models and Key Dimensions
Metso HP Series (HP100-HP800), GP Series (GP100-GP550) and MP Series
Materials and Processes
Select the material grade and heat treatment for the operating conditions, processed material and equipment specifications. The options below are commonly used; confirm the final grade against the drawing and technical agreement.
Alloy steel 42CrMo4 (EN 10083-3)
Candidate material for forged steel pinions; quenching and tempering, tooth surface hardening and mechanical property requirements depend on loading, dimensions and the drawing.
Alloy steel 20CrMnTi
Carburizing gear steel; verify effective case depth and surface and core hardness against the gear drawing and load requirements.
Alloy steel 34CrNiMo6 (EN 10083-3)
Candidate quenched and tempered alloy steel; suitability and mechanical properties depend on drive loads, section size and drawing requirements.
Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- Tooth flank contact fatigue begins as small pits and can progress to extensive spalling
- Tooth flank scoring: inadequate lubrication under high speed and heavy loading causes local welding and tearing
- Tooth root bending fatigue: repeated pulsating loads cause root cracks and can lead to broken teeth
- Abrasive tooth flank wear: contaminated oil accelerates surface material loss
Replacement criteria
Assess replacement against the pitting, tooth thickness and backlash limits in the gear drawings and maintenance specification. Replace immediately if tooth root cracks occur. Inspect the pinion and gear together for wear and meshing condition.
Material and Process Control
Materials, heat treatment, composite processes and inspection follow the specific drawing, duty and technical review.
Material Grade / Substrate
Alloy steel 42CrMo4 (EN 10083-3), alloy steel 20CrMnTi and alloy steel 34CrNiMo6 (EN 10083-3)
Heat Treatment Condition
Quenching and tempering, tooth or surface induction hardening, or carburizing and quenching. Verify final hardness and microstructure against the drawing and technical agreement.
Composite / Hardfacing Requirements
Repair eligibility, procedures and acceptance criteria for high-manganese steel liners must follow the specific part drawing and an approved repair plan. Ceramic tiles and composite plates are not universal substitutes.
Dimensions and Inspection
Manufacture to drawings produced from part measurements or supplied by the customer. Critical mating surface tolerances follow OEM requirements. Use UT/MT inspection to assess castings for shrinkage porosity and cracks against the agreed acceptance criteria.
Parts with the same name may not be interchangeable across models, drawing revisions, interfaces and materials. Confirm the full model, serial number and drawings before manufacture.
