Bronze bushes (also known as bronze bushings) are critical components in cone crushers, providing wear resistance, load-bearing capacity, and smooth operation. They are commonly used in the eccentric assembly, countershaft, and other high-friction areas of the crusher.
Key Applications of Bronze Bushes in Cone Crushers
1. Eccentric Bush – Fits between the main shaft and the eccentric assembly, allowing smooth rotation under heavy loads.
2. Countershaft Bush – Supports the countershaft in the lower frame of the crusher.
3. Head Center Bush – Found in the main shaft housing to reduce friction.
4. Thrust Bearings Support – Sometimes used as thrust washers or wear plates.

Common Bronze Alloys Used
– SAE 660 (C93200 / B14) – High-lead tin bronze, excellent for high-load, low-speed applications.
– SAE 841 (C84400) – Leaded red brass, good for moderate loads.
– Aluminum Bronze (C95400 / C95500) – Higher strength and corrosion resistance for harsh conditions.

Advantages of Bronze Bushes in Cone Crushers
✔ Self-Lubricating Properties – Retains lubrication for longer service life.
✔ High Load Capacity – Handles heavy crushing forces without deformation.
✔ Shock Absorption – Reduces vibration and noise during operation.
✔ Wear Resistance – Prolongs lifespan compared to steel-on-steel contact.
Maintenance & Replacement Tips
– Regularly check for wear using clearance measurements.
– Ensure proper lubrication (grease or oil) to prevent premature failure.
– Replace bushes when excessive play or scoring is detected.
– Use OEM or high-quality aftermarket bushings to ensure compatibility.
