Main Shaft

Main Shaft is a critical component of the Screw Press used in palm oil extraction. It transmits rotational force from the motor to the Worm Screw, which applies high pressure to compress fresh palm fruits (FFB) and extract oil from the fibrous pulp.

Due to its role under continuous high torque and pressure, the Main Shaft must be made from highly durable materials that can withstand wear, impact, and friction, ensuring optimal performance and extended service life of the machine.

Main Shaft Features

• High Torque and Pressure Resistance
  Designed to withstand extreme force generated during the pressing process for stable and reliable performance.

• Made from High-Quality Materials
  Commonly manufactured from Carbon Steel or special alloys that are heat-treated for enhanced strength and wear resistance.

• Easy Installation and Maintenance
  Shaft design allows for convenient replacement and reduces machine downtime.

• Improves Oil Extraction Efficiency
  Ensures maximum oil is pressed from the fruit pulp during the process.

Types of Main Shaft

• Standard Main Shaft
  Suitable for general-purpose screw presses with normal production capacity.

• Heavy-Duty Main Shaft
  Built to withstand higher pressure for high-capacity industrial applications.

• Custom-Made Main Shaft
  Tailored specifications for specific press models and operational needs.

Applications of Main Shaft

• Palm Oil Mills – Transfers torque in screw presses to extract crude palm oil (CPO) from fiber.

• Biodiesel Plants – Supports pressing operations for biofuel feedstock production.

• Vegetable Oil Processing Plants – Used in high-force extraction for various edible oils.

Advantages of Main Shaft

• Enhances performance and reliability of the palm oil screw press.

• Reduces wear on internal press components.

• Engineered to endure high torque and mechanical stress.

• Easy to install and maintain, minimizing downtime and maintenance costs.

• Maximizes oil extraction efficiency for increased yield.
