A cone crusher can contain several bronze bearing surfaces. An eccentric bushing, a head bushing and a socket liner do different jobs; a part called a mainshaft sleeve may not even be bronze. To identify a replacement, start with its assembly position and the crusher’s parts drawing. Similar appearance does not establish interchangeability.
The arrangement depends on the machine model. Here is what to identify before ordering a made-to-drawing part.
Which Cone Crusher Parts Are Bushings, Sleeves or Liners?
The drive turns an eccentric assembly, moving the crushing head around the fixed axis. Its sliding surfaces need the specified fit and lubricant supply. Parts lists reuse names for different geometries, so check the assembly position.
| Part name you may see | Location | Sliding interface or role |
|---|---|---|
| Eccentric bushing | In or around the eccentric assembly; some models use inner and outer bushings. | Bearing surface for eccentric motion. |
| Upper and lower head bushings | Separate positions in the moving head on certain designs. | Sliding contact with the specified journal. |
| Socket liner | Between the head ball and socket, where that design is used. | Curved sliding contact supporting the head ball. |
| Countershaft box bushing | In the drive-side countershaft box on relevant models. | Sliding support for the countershaft. |
The mantle and bowl liner are crushing wear liners, not bronze bushings. Some drawings specify a main shaft bushing as a bearing part; a mainshaft sleeve can be a separate component. Do not assume the sleeve’s material or confuse it with an eccentric bushing.
These are not alternative names for one cylinder. A crusher may also have thrust components carrying axial load; check their own drawings instead of grouping every bronze-colored part under “eccentric bushing.”
For symptoms and measurement points specific to the eccentric, see our cone crusher eccentric bushing failure guide.
Why Must Bronze Grade and Oil Features Match the Drawing?
“Bronze bushing” does not identify one material. Different crusher designs may specify different cast bronze alloys. Load, speed, temperature, mating surface and lubricant affect the choice. Follow the approved alloy callout or have the machine owner and engineer approve any change; matching dimensions alone is insufficient.
The housing fit and shaft running clearance are different requirements. A press fit can change the installed bore, so clarify whether final dimensions apply before or after pressing. For a flange, shoulder or spherical face, specify its reference surfaces and axial location as well as ID, OD and length.
Oil holes and grooves must align with the machine’s lubrication route. Record their size, position and orientation rather than copying another crusher’s pattern. For a socket liner, the curved contact profile and oil distribution matter as much as nominal diameter.
A universal clearance or generic “crusher bronze” grade cannot establish suitability across different models.
On the manufacturing drawing, identify datums and tolerances for locating surfaces. Note required roundness, concentricity, surface finish and edge breaks. Distinguish free-state from installed measurements. If the OEM specification is missing, resolve these points with the equipment owner; a photograph cannot supply engineering limits.
How Can You Tell Similar Replacement Parts Apart?
Identify the manufacturer, model, serial number and assembly location, then compare the part number and drawing revision with the parts list. Machines in the same family may have design changes. “Head bushing” or “socket liner” alone cannot confirm a match.
If a crusher has been rebuilt or upgraded, confirm the revision of the mating assembly too. An older serial number may not describe the parts currently installed.
Compare the mating shaft or head ball, housing seat and retaining features. A new bushing will not fix an out-of-round housing or damaged journal. A removed part may have worn or distorted since installation; note which sample surfaces remain reliable and which dimensions need confirmation from the assembly.
A photo of an upper head bushing can show groove direction, but cannot prove installed running clearance. A socket liner’s OD does not define its working radius. Ask for mating-part measurements and agree how uncertain geometry will be verified before machining.
For purchasing, identify each assembly location and part number separately. Supply the approved alloy, finished tolerances, contact geometry, oil details, quantity and inspection requirements. That information lets the manufacturer quote the actual components rather than guess from a crusher model.
Send Your Cone Crusher Bronze Part for Review
JED manufactures bronze components to supplied drawings for mining machinery. A shaped socket liner or other nonstandard bearing surface can be reviewed through our custom bronze parts capability.
Contact JED with the crusher model, part number, drawing or sample photos, quantity and required date. Add mating dimensions and oil-hole layout where available. We will review geometry, material and inspection scope before quoting.
FAQ
Can I order only the upper or lower head bushing?
Yes, you can request a quotation for an individual part. Identify its exact position and part number; your maintenance team should assess the mating surface and the other bushing before deciding whether one-part replacement is appropriate.
Can you quote a socket liner from a worn sample without a drawing?
A sample and photos can start a review, but a worn spherical surface may not show the original profile. Provide the mating component, earlier measurements or an approved drawing where possible. Critical geometry must be confirmed before manufacture.
Can several crusher bushings be marked and inspected separately?
Specify the part numbers, quantities, identification marks and required reports in the purchase request. Separate marking and inspection can then be agreed for each component, so a maintenance team can match delivered parts to their assembly locations.
