The “Sacrificial Heart” of Your Crusher: Cast Bronze Bushings Explained
In the high-pressure world of mineral processing, Cast Bronze Bushings are key wear components in your cone crusher.
They function as “sacrificial” components—engineered to wear out so that your multi-million dollar steel mainshafts and frames don’t.
Application Areas & Material Selection Guide
| Category | Component (EN) | Recommended Grade (ASTM/SAE) | Engineering Logic |
| High-Load Bushings | Eccentric Bushing/Head Bushing | High-Lead Tin Bronze (C93700 / SAE 64) | Highest load area. High lead content provides critical self-lubrication to prevent “seizure” if the oil film breaks under extreme crushing force. |
| High-Speed Rotation | Countershaft Bushing/Frame Bushing | Leaded Red Brass/Bronze (C93200 / SAE 660) | Highest RPM. Offers the best balance of wear resistance and thermal conductivity to dissipate heat generated by fast rotation. |
| Thrust & Support | Socket Liner (Bowl)/Thrust Bearing Plate | High-Leaded Bronze (C93800 / SAE 67) | Vertical Load Hub. Must support hundreds of tons of crushing force while allowing smooth gyratory movement via precision oil grooves. |
| Guiding & Aux | Piston Guide/Spider Bushing | Aluminum Bronze (C95400 / C93200) | Friction & Alignment. Aluminum bronze (C95400) is used when extreme hardness is required to prevent galling in hydraulic piston movements. |
Why Cast Bronze? (The Expert’s “Skeptical” Insight)
-
Emergency Self-Lubrication: Unlike steel-on-steel, bronze contains lead “pockets.” If lubrication fails momentarily, the lead smears across the surface to prevent a catastrophic “cold weld” (seizure).
-
Particulate Embeddability: Crushing sites are dusty. Bronze is soft enough to allow microscopic dust particles to embed into the bushing surface rather than scratching the expensive hardened steel shaft.
-
Thermal Management: Cast bronze is an excellent heat conductor. it pulls friction heat away from the contact surface and into the oil circulation system, preventing thermal expansion issues.
Expert Maintenance Pro-Tip:
Your bushings are a diagnostic tool. If you see pitting or discoloration (blackening) on a bronze bushing during inspection, don’t just replace the part. Check your oil viscosity, temperature, and micron filtration. The bronze failed for a reason—it likely saved your mainshaft from a total breakdown.

Q1. Which bronze grade should I choose for a cone crusher bushing?
A: Grade follows the bushing position, load and speed. Use high-lead tin bronze (C93700 / SAE 64) for high-load eccentric and head bushings; leaded red brass (C93200 / SAE 660) for high-speed countershaft and frame bushings; high-leaded bronze (C93800 / SAE 67) for thrust and socket liner; aluminum bronze (C95400) for spider and piston guide. Match the grade to your duty cycle and send the drawing for confirmation.
Q2. What is the relationship between CuPb15Sn8 and C93800?
A: CuPb15Sn8 is a GB (China) standard designation for high-lead tin bronze. C93800 is the closest UNS equivalent (also referenced as SAE 67). They are not identical specifications, but are commonly cross-referenced in sourcing. Always confirm the exact chemistry and dimensions against your drawing before ordering.
Q3. Do you need a drawing or a worn sample to make a bushing?
A: Yes. Supply a 2D drawing with tolerances, or a worn sample for reverse engineering. Include the bronze grade, key dimensions, oil groove layout and the bushing position in the crusher. This lets us match fit and function to the original part.
Q4. Are these bushings suitable for stone, rock and aggregate crushers?
A: Yes. Cone crushers in stone, rock and aggregate plants operate under abrasive dust and boundary lubrication. High-lead bronzes and graphite-impregnated (oilless) options are used for that duty. The right choice depends on load, speed and how the lubrication system is set up.
Q5. Lead bronze versus graphite-impregnated bushing – which should I use?
A: High-lead tin bronze (C93700 / C93800) carries lead that smears to give emergency lubrication if the oil film breaks. Graphite-impregnated (oilless) bushings hold solid lubricant in the structure and suit positions that are difficult to lubricate or where downtime for greasing is a concern. Choose by lubrication access and duty cycle.
Q6. How are bronze cone crusher bushings installed?
A: Most are interference-fit parts installed by shrink fitting, often with dry ice, with the oil holes aligned to the oil passages. Soak times and the method follow the crusher service manual and the part size. Confirm the fit class with your drawing before machining.
Q7. How much does a cone crusher bushing cost?
A: Price depends on the bronze grade, size, quantity and machining tolerance. Send the drawing or part number and we quote per enquiry. We do not publish a single list price because each part is made to specification.
Q8. Do you supply OEM or aftermarket cone crusher bushings?
A: We supply aftermarket, interchangeable bushings made to your drawing or worn sample. Crusher and brand names are shown for reference only and do not imply any affiliation with the original equipment manufacturer. We are not an OEM representative.
Q9. What is the lead time and minimum order quantity?
A: Rough cast parts are typically about two weeks; finished machined parts about eight weeks, depending on workshop load and size. Minimum order quantity is reviewed per part, and small batches are supported. Confirm current timing with your enquiry.
Q10. Can I get a cone crusher bushing catalog or PDF?
A: The downloadable catalog is being updated. Send your enquiry and we will provide the current catalog and product list by email. This also lets us match the right grade and size to your crusher model.
