Identify parts for Metso cone crushers, check models and drawing numbers, confirm materials and processes, and submit an inquiry.
Equipment, Models and Drawing References
Identify the installed machine model and key dimensions, then check the part number, drawing number, drawing revision and physical interfaces.
Models and Key Dimensions
Metso HP Series (HP100-HP800), GP Series (GP100-GP550) and MP Series
Drawing Number / Part Number
See the OEM part number table below
Provide the equipment nameplate, complete model and existing part number so that the installation position and drawings can be checked.
Drawing Revision
Confirm dimensions by measuring the sample or using the customer drawing. Cross-check the drawing revision against the model on the equipment nameplate.
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 gears; quenching and tempering, tooth surface hardening and mechanical property requirements depend on gear size, loading 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.
Cast steel GS-42CrMo4
Cast blanks for large gears, with teeth machined after quenching and tempering; a candidate for large-module gears
Wear and Replacement Criteria
Common wear patterns and maintenance guidance are outlined below. Determine replacement intervals from operating conditions, processed material and equipment performance data.
Common Wear Patterns
- Tooth flank pitting: surface metal loss caused by contact fatigue
- Tooth flank scoring: inadequate lubrication causes local welding and tearing of the contacting surfaces
- Tooth root bending fatigue cracks: repeated pulsating loads can cause tooth root fracture
- Abrasive tooth flank wear: metal particles in the lubricant accelerate surface wear
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. Check pinion wear when replacing the gear wheel.
Materials and Processes
Materials, heat treatment, composite construction and inspection requirements depend on the specific drawing, operating conditions and technical review.
Material Grade / Substrate
Alloy steel 42CrMo4 (EN 10083-3), alloy steel 20CrMnTi and cast steel GS-42CrMo4
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 because of differences in machine model, drawing revision, mounting interface or material specification. Use the complete model, serial number, drawing number and drawing before manufacture.
