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.
Jaw crushers rely on more than just jaw plates and cheek plates. A wide range of non-wear spare parts support the structure, motion, and adjustment of the machine. These parts include:
Structural assemblies (e.g., frame, pitman)
Drive and transmission components (V-belts, pulleys, flywheels)
Adjustment systems (hydraulic cylinders, wedges)
Bearings (eccentric, thrust, support)
Toggle plates and toggle seats
Fasteners (bolts, nuts, washers)
Seals, gaskets, and guards
These components are essential for maintaining safe and efficient operation.
Quality spare parts ensure:
Proper fit and mechanical performance
Reduced vibration, fatigue, and premature wear
Reliable machine operation with minimal downtime
Safety for operators and surrounding equipment
Substandard parts can lead to breakdowns, alignment issues, and long-term damage to other critical components.
Accurate identification is critical. To determine the right part:
Locate the crusher’s model and serial number
Consult the OEM parts manual or assembly diagrams
Record the part name and part number/code
Compare specifications with trusted aftermarket catalogs or contact technical teams with experience in jaw crusher assemblies
This process helps avoid mismatched or incompatible components.
Even though these components don’t directly crush material, they wear over time due to vibration, force, or environmental conditions.
Common examples include:
Toggle Plates and Seats – Transmit crushing force; protect against overload
V-Belts – Stretch and crack with usage; require tension checks and replacement
Bearings – Need regular lubrication and wear monitoring
Hydraulic Cylinders and Accumulators – May develop seal wear or leakage
Fasteners – Can loosen due to mechanical stress
Seals and Gaskets – Degrade under heat, pressure, and dust
Safety Guards – Should remain intact to protect against debris and moving parts
Regular maintenance allows:
Consistent output and throughput
Smooth, low-vibration operation
Lower energy consumption
Prevention of cascading component failure
Cost-effective long-term operation
The best source for jaw crusher spare parts depends on machine compatibility, delivery times, and technical support. Look for suppliers that offer:
Compatibility with your crusher brand and model
Clear technical documentation and product identification tools
Engineering support and proven service experience
Quality certifications and material traceability
