The search for Symons cone crusher parts often involves equipment that has been operating, repaired, or rebuilt for many years. In these cases, the original machine name may still be clear while the installed bearing, bushing, shaft, or housing details have changed.
Metso currently supports Symons crushers and lists parts support for multiple legacy sizes, including 2, 3, 4¼, 5½ and 7 ft crushers. This long service history explains why model identification and actual installed-part verification should be used together.
Legacy crushers can remain economically useful when plants maintain them correctly and have access to suitable replacement parts.
Typical inquiries may involve:
However, older machines may no longer match their original configuration. Shaft repairs, housing machining, upgraded components, or previous aftermarket replacements can change what is actually installed. For this reason, old equipment should not be sourced from model name alone.
An original part number is valuable, but several additional checks may still be required.
Buyers should compare:
A part number can identify the original design, while the physical machine confirms whether that design still applies.
This is especially important for bearings because a repaired shaft or housing can change the required fit even when the bearing designation remains unchanged.
Bearing condition is influenced by the complete support and drive system.
Components to review include:
General crusher-bearing guidance shows that cone crushers can operate under heavy loads and load spikes, with specialized bearing arrangements chosen for the particular machine. Correct fits and lubrication remain important to bearing performance.
Therefore, a bearing failure should trigger inspection of its mating shaft, housing, lubricant, and surrounding components.
Legacy Telsmith cone crusher parts and Allis Chalmers cone crusher parts inquiries can present the same practical sourcing problem: the buyer may have an old reference but incomplete information about the component currently installed.
Astec continues to list Telsmith parts and service support, while FLS currently publishes replacement-component information for Allis-Chalmers and Svedala Hydrocone crushers. The latter includes assemblies such as eccentric, pinionshaft, mainshaft, Hydroset, topshell, and bottomshell components.
For an independent bearing supplier, these references should only be used to identify the machine family. The actual bearing or custom component still requires dimensional and structural verification.
Drawings and measurements become particularly important when:
Useful measurements include bore, outside diameter, width, shoulders, radii, grooves, and locating features.
The buyer should also record shaft diameter, housing bore, clearance requirements, lubricant method, and load direction where known.
A damaged sample can support reverse confirmation, but it should not be the sole dimensional reference.
HSN can review difficult-to-source crusher bearing inquiries from a model number, old bearing code, drawing, sample, or measured dimensions.
The process may include:
Before shipment, HSN focuses on dimensional tolerance, hardness, and clearance. Other checks can be discussed according to customer requirements.
HSN is an independent bearing supplier and does not present replacement products as original Symons, Telsmith, or Allis-Chalmers parts.
Why are Symons parts still requested?
Many older crushers remain in service, so buyers still need wear, spare and bearing-related replacement components.
Is an old part number enough?
Not always. Check the installed dimensions, machine position and previous repair history before replacement.
Can old crusher bearings be customized?
Yes, after the bearing structure, dimensions, fits, clearance and operating requirements are confirmed.
What should buyers send HSN?
Send the model, old reference, photos, drawings, dimensions, quantity and working conditions.
For detailed cone crusher bearing models not covered here, please contact HSN for model confirmation and supply discussion. For other bearing types, you can also send the complete reference, photos, dimensions, quantity and working conditions.
