Lower Cheek Plates
Lower Cheek Plate
Identify parts for Metso jaw crushers, check models and drawing numbers, confirm materials and processes, and submit an inquiry.
Equipment, Models and Part Numbers
Lower cheek plates protect both frame sidewalls in the lower crushing chamber from fine-material abrasion. Wear is often heavier than on upper cheek plates. The part numbers below identify Metso Nordberg C Series jaw crusher parts and require confirmation against the installed machine.
Applicable Models
C80, C96, C100, C106, C110, C120, C125, C130, C140, C150, C200, C3054

Materials and Processes
Review the following lower cheek plate material and process information when assessing specifications and alternatives.
XT710 manganese steel
Verify cheek plate material against the specific part drawing and material certificate. The XT710 designation alone does not establish composition or hardness.
Mn13Cr2 / Mn18Cr2
Select lower cheek plate material for impact, abrasion and the actual wear profile. Manganese or chromium content alone does not predict service life.
Alternative material options
Assess alternative cheek plate materials for the specific model, impact load, thickness and fastening arrangement. Quoted materials and acceptance requirements are defined by the technical agreement.
Wear and Replacement Criteria
Use the following lower cheek plate wear patterns and replacement considerations during maintenance.
Main wear zones
High-velocity material flow near the discharge, generally the heaviest wear zone; around bolt holes; and at the lower jaw plate interface.
Replacement Criteria
Assess remaining thickness against the model-specific maintenance limits. Stop and inspect if there is wear-through or cracking.
Recommended Actions
Inspect lower cheek plates more frequently and measure thickness regularly. Check for uneven feed loading if excessive localized wear develops.
Information Needed for an Inquiry
