    Customized Forging Blank Spline Shaft Low Speed Shaft High Speed Shaft Spindle

    Steel Forging Blank Spline Shaft Low Speed Shaft High Speed Shaft Spindle. Our steel forging blanks are the robust starting materials for critical rotating components: spline shafts, low-speed shafts, high-speed shafts, and spindles. Precision-forged, these blanks achieve superior internal grain structure and enhanced mechanical properties. This ensures the final machined parts offer exceptional strength, durability, and fatigue resistance for reliable power transmission and precise rotational control in demanding industrial uses.


    Product Features

    • Optimized Internal Grain Flow: Forging enhances strength, toughness, and fatigue resistance, crucial for dynamic loads.
    • Superior Mechanical Integrity: Offers increased tensile strength, yield strength, and resistance to torsional/bending stresses.
    • Ideal for Precision Machining: Dense, homogeneous microstructure provides an excellent foundation for tight tolerances and intricate geometries.
    • Enhanced Durability: Leads to extended service life and reduced maintenance due to inherent resistance to wear and cracking.
    • Customizable Material & Dimensions: Available in various steel grades and customizable to meet specific application needs.

    Application Scenarios

    These steel forging blanks are essential precursors for key shafts and spindles across many industries:

    • Spline Shafts: Used in automotive drivetrains, industrial gearboxes, and agricultural machinery for torque transmission and precise meshing.
    • Low Speed Shafts: Critical for wind turbines (main shafts), heavy industrial mixers, and mining/conveyor systems handling high torque at low RPMs.
    • High Speed Shafts: Essential for wind turbines (generator output), pumps and compressors, and turbochargers requiring high rotational speeds.
    • Spindles: Core components in machine tools (CNC, lathes), automotive wheel hubs, and textile machinery demanding high precision and rigidity.
