Cone Crusher Bronze Bushings: The Definitive Guide to Types, Functions & Materials
Primary Bushing Types & Functions
-
Location: Mounted inside the eccentric assembly at the base of the crusher.
-
Function: The heart of the crusher’s motion. It converts the rotational energy of the gears into the gyratory crushing action. It must endure immense eccentric torque and high-speed sliding contact while dampening vibrations.
-
Location: Pressed into the countershaft box.
-
Function: Supports the pinion shaft, handling the high-speed rotational loads transferred from the drive pulley or electric motor. It requires excellent thermal conductivity to manage heat buildup from high RPMs.
-
Location: Fitted inside the frame’s center housing, surrounding the main shaft.
-
Function: Acts as the primary radial bearing for the main shaft, directly withstanding the massive radial crushing forces generated during operation and protecting the shaft from wear.
-
Location: Positioned within the socket assembly, supporting the underside of the moving head (mantle assembly).
-
Function: Supports the spherical head (journal), enduring tremendous vertical crushing forces and complex overturning moments. It is vital for maintaining the stability of the crushing cavity.
Critical Bronze Bushing Applications in Cone Crushers
-
Spider Bushing: Serves as the central pivot point supporting the entire upper assembly. A failure here is catastrophic. Premium grades like ZCuPb20Sn5, ZCuPb10Sn10, and ZCuPb24Sn5 are essential for durability under extreme spider loads.
-
Main Shaft (Head) Upper Bushing: Guides the main shaft within the spider bore. A precision fit is critical for stable mantle movement and preventing off-center loading.
-
Bottom Shell Bushing: Supports the lower end of the main shaft, ensuring perfect alignment and smooth operation within the bottom shell.
-
Piston Wearing Plate: Works in conjunction with the socket liner to transmit hydraulic force and allow for CSS (Closed Side Setting) adjustments.
-
Upper Thrust Bearing: Manages the intense axial thrust loads generated during the crushing process, often working as part of a multi-plate thrust bearing set.

Cone Crusher Bronze Bushings: The Heartbeat of Your Crushing Performance
When your cone crusher grinds to a halt, productivity plummets. Unplanned downtime isn’t just an inconvenience; it’s a direct hit to your bottom line. Often, the unsung heroes – or potential failure points – lie within the precision bronze bushings silently ensuring smooth operation under immense pressure and friction.
Why Bronze Bushings are Non-Negotiable for Cone Crushers:
Unlike standard steel components, high-quality bronze bushings (like ZCuPb20Sn5, ZCuPb10Sn10, ZCuPb24Sn5) are engineered for the unique demands of cone crushers:
-
Exceptional Wear Resistance: Withstands the constant sliding friction between major components.
-
Embeddability: Small abrasive particles embed into the softer bronze, protecting the harder steel shafts from scoring and galling.
-
Conformability: Accommodates minor misalignments, distributing load more evenly.
-
Low Friction Coefficient: Reduces heat generation and power consumption.
-
High Load Capacity: Supports the tremendous forces generated during rock crushing.
-
Corrosion Resistance: Performs reliably in challenging operating environments.
Choosing the Right Bronze Bushing Partner:
Not all bronze is created equal. The specific alloy composition and precise manufacturing tolerances are paramount. Look for:
-
Certified Materials: Guaranteed adherence to ZCuPb20Sn5, ZCuPb10Sn10, ZCuPb24Sn5, or other specified crusher OEM grades.
-
Precision Machining: Bushings must meet exact dimensional tolerances for perfect fit and optimal oil film formation.
-
Rigorous Quality Control: Every bushing should be inspected for material integrity, dimensions, and surface finish.
-
Proven Performance: Supplier reputation for longevity and reliability in demanding mining and aggregate operations.
Maximize Uptime, Minimize Cost:
Investing in premium cone crusher bronze bushings – Spider Bushings, Eccentric Bushings, Socket Liners, Head Upper Bushings, Bottom Shell Bushings, Thrust Bearings – isn’t an expense; it’s a strategic decision for:
-
Reduced Unplanned Downtime: Minimize costly crusher stoppages.

How Do Crusher Bearings Work?
The Working Principle Of The Crusher
The motor drives the pulley through the small pulley and v-belt, then the pulley drives the drive shaft, large and small bevel gears rotate, and the large bevel gears drive the eccentric sleeve rotates, Finally, The mantle rotates and swings under the forced movement of the eccentric shaft. The section of the mantle close to the concave becomes the crushing cavity. After being pressed and impacted by them, the material is broken and discharged from the bottom of the cone crusher due to gravity.
Cone Crushers Bushing Application
Cone crushers are widely used in many industries such as mining, smelting, building materials, highways, railways, water conservancy, and chemical industries.

How To Deal With The Failure Of Holding Shaft Burn Sleeve
When the temperature rise of the Cone Crusher Bushings is 50 ℃, the thermal expansion of the outer diameter is 0.31 mm. so the clearance between the copper sleeve and the eccentric sleeve should be not less than 0.31 mm, and the clearance between the bore of the Crusher Bushings and the main shaft should not be less than 0.35 mm, to ensure the design clearance between the copper sleeve and the main shaft, so as not to occur shaft burning failure.
CuSn5Zn5Pb5 Cone Crusher Copper Sleeve
Cone Crusher Bushing because of its use of the environment, we generally choose a more wear-resistant, affordable, and appropriate copper material, which is more suitable for the CuSn5Zn5Pb5 material.
- Material: CuSn5Zn5Pb5

We can customize the material, such as brass, bronze, tin bronze and phosphor bronze, to ensure the wear resistance, pressure resistance and corrosion resistance of the copper sleeve, and more in line with the high specifications of the cone crusher on the copper sleeve, so as to meet the smoother and longer service life of the cone crusher copper bushing.


Common Problems And Solutions With Cone Crusher Sleeve Bearings
- Overheating is a common issue with sleeve bearings. Ensuring adequate lubrication and regular cleaning can prevent this.
- Excessive wear is often a result of inadequate lubrication or misalignment. Regular inspection and maintenance can mitigate this problem.
- Misalignment can cause uneven wear and tear. It’s crucial to ensure correct installation and carry out regular checks to avoid this. If misalignment occurs, immediate correction can prevent further damage and maintain optimal crusher performance.
Choosing the right sleeve bearing for your cone crusher is critical. Factors such as the crusher’s operational speed, load, and environment should be considered. Additionally, the bearing material and design should be suitable for the specific application. Consulting with a bearing specialist or the crusher manufacturer is recommended for the best results.
