Cone crushers play a vital role in mining and aggregate production, particularly in secondary and tertiary crushing stages. Their stable operation ensures consistent particle size control and steady plant output. Core components such as the mainshaft, bushings, and eccentric assembly are subject to high-impact forces and are key to overall system durability and efficiency.
As a professional aftermarket manufacturer, GUBT supplies high-quality, fully compatible replacement parts engineered to improve reliability, reduce maintenance costs, and maximize long-term returns.

Eccentric Assembly: A key mechanism that drives the mainshaft in an eccentric path, influencing crushing stroke and output efficiency.
Mainshaft: The central rotating shaft that transmits torque and bears vertical loads, critical to the crusher’s drive system.
Bushing: A wear-resistant sleeve, usually made of bronze, used between moving and fixed parts to reduce friction and ensure alignment.
Hydraulic Cylinder: A hydraulic actuator used for CSS adjustment, overload protection, or lifting assemblies during maintenance.
Adjustment Ring: A structural ring for controlling the Closed Side Setting (CSS); many models use hydraulic mechanisms for precise, on-the-fly adjustment.
Torque Arm: A structural support that stabilizes and aligns torque transmission, especially in eccentric drive configurations.
Locking Nut: A securing component that holds the crushing head assembly in position, preventing loosening due to vibration or cyclic loads.
Backstop Device: A safety mechanism designed to prevent reverse rotation of the mainshaft during shutdown or abnormal operation.
Flow Divider: A hydraulic control element that evenly splits fluid flow between multiple cylinders or actuators.
Hydraulic Filter: Maintains fluid cleanliness within the hydraulic system, protecting components and ensuring stable system pressure.
When should the mainshaft be replaced?
If you notice overheating, unusual vibration, or visible cracks, the mainshaft should be replaced immediately to prevent further damage.
What causes the adjustment ring to bounce?
This may result from uneven feed, overloading, or loose contact between components. Check the weight balance and ensure all fasteners are properly tightened.
Is GUBT an OEM?
No. GUBT is a professional aftermarket manufacturer offering high-quality, OEM-compatible parts at competitive prices.
Does GUBT maintain stock for fast-moving parts?
Yes. GUBT holds large inventories of critical wear and structural components like bushings, wedges, and assemblies to ensure fast delivery worldwide.
How should the hydraulic system be maintained?
Regularly check hydraulic oil levels, clean filters, and inspect system pressure and responsiveness to avoid failures or delays.
