Sintered Inner Outer Rotor Set: Technical Specifications, Applications, and Advantages
A Sintered Inner Outer Rotor Set consists of two critical rotor components manufactured using sintering technology, where powdered metal is fused under high heat and pressure. This process creates a dense, high-strength material capable of withstanding extreme operating conditions such as high pressure, temperature, and continuous rotational forces.
Key roles of the rotor set include:
- Efficient hydraulic energy transfer
- Smooth rotational motion in pumps and motors
- Minimized wear and tear due to optimized material properties
Growth Industries ensures that every rotor set meets international standards for performance and durability, making it suitable for heavy-duty applications in industrial, automotive, and OEM machinery.
Material Composition and Manufacturing Process
The sintered rotor set is manufactured using:
- Powdered steel or alloy powders – selected for high tensile strength and corrosion resistance
- Sintering process – powdered metal is compacted and heated just below its melting point
- Precision machining – ensures exact tolerances for seamless operation
- Surface treatments – may include nitriding or coating to reduce friction and enhance lifespan
Benefits of this manufacturing process include:
- Enhanced mechanical strength
- High dimensional accuracy
- Porosity control for oil retention in hydraulic applications
- Improved wear resistance
