Cone Crusher Bushing System
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 (MP800-MP1000)
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.
C95400 aluminum bronze (ASTM B148)
Aluminum bronze; verify composition, casting method, heat treatment condition and mechanical properties against the applicable material standard and part drawing.
Aluminum bronze C95500
Nickel-aluminum bronze; verify mechanical properties for the specified casting and heat treatment condition against the bushing drawing.
C93200 leaded tin bronze (SAE 660)
Cu-Sn-Pb-Zn bearing alloy; select for the load, speed and lubrication conditions, and maintain the lubrication required by the equipment.
Wear Characteristics and Replacement
Common wear modes and maintenance advice. The actual replacement interval depends on duty, material and operating data.
Common wear modes
- Bushing bore wear increases eccentric clearance and excessive mainshaft movement
- Inadequate lubrication causes bushing surface scuffing and galling
- Foreign particles in the lubrication system cause grooves in the bushing surface
- A loose fit between the bushing and housing bore causes fretting wear
Replacement criteria
Assess bushing bore wear and fitting clearance against the equipment maintenance manual. Stop and inspect if extensive scuffing, galling or abnormal copper debris in the oil is found. Base replacement on inspection results and model-specific requirements. Measure the housing bore before installation and control interference to the drawing.
Material and Process Control
Materials, heat treatment, composite processes and inspection follow the specific drawing, duty and technical review.
Material Grade / Substrate
Aluminum bronze C95400 (ASTM B148), aluminum bronze C95500 and leaded tin bronze C93200 (SAE 660)
Heat Treatment Condition
Select the heat treatment condition for the specific copper alloy grade and part drawing; verify final hardness and microstructure against the technical agreement.
Composite / Hardfacing Requirements
Bronze bushings are not suitable for weld overlay repair. Replace the worn bushing as a complete part; surface repair is not recommended.
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.
