✅ Basic Description

Name: Cone Crusher Nylon Bushing
Material: Engineering plastic (usually MC Nylon or modified nylon)
Function: Lubrication support, wear resistance, vibration damping, and shaft alignment
Placement: Between the main shaft, eccentric bushing, or frame components of cone crushers

? Key Features

1. Wear Resistance – Nylon bushings are highly resistant to abrasion, extending service life in harsh environments like stone crushing and mining.

2. Self-lubricating – Reduces the need for frequent lubrication; minimizes friction during operation.

3. Shock Absorption – Helps absorb vibration and impact between metal components.

4. Corrosion and Chemical Resistance – Performs well in dusty, wet, or chemically exposed environments.

5. Lightweight and Machinable – Easy to produce and replace; suitable for custom-made sizes.

? Common Materials Used

• MC Nylon (Cast Nylon): Most common material due to its excellent mechanical strength and wear resistance.

• Oil-filled Nylon / Lubricated Nylon: Enhanced with internal lubricants to improve performance.

• Glass-fiber reinforced Nylon: For applications requiring higher stiffness and dimensional stability.

• Other options: UHMW-PE or POM, depending on load and temperature requirements.

⚙️ Common Applications in Cone Crushers

• Between eccentric sleeve and main shaft

• Between main shaft and bottom frame

• Between moving cone and fixed cone parts

• In lubrication systems as a bearing interface

Typical cone crushers that use nylon bushings:

• Metso® HP series (e.g. HP300, HP500)

• Symons® cone crushers (e.g. 3ft, 4.25ft)

• Sandvik® CH/CS series

• Chinese domestic brands like SANDMINE, DSMAC, etc.

?️ Typical Industries

• Mining and quarrying

• Aggregates production

• Cement plants

• Metallurgical crushing systems

• Sand and gravel processing
