FAQs:
  • What materials are used for your custom spline shafts?
    Our spline shafts are primarily manufactured from AISI 4140 steel, which undergoes carburizing heat treatment to achieve a surface hardness of 58-62HRC. We also work with equivalent steel grades including 42CrMo, SCM440, and other international standards.
  • What manufacturing processes are involved in creating these spline shafts?
    We utilize precision spline milling and spline grinding processes to create the deep grooves and precise gear profiles. Teeth grinding is included in our manufacturing to ensure high accuracy and proper fit with mating components.
  • Can you customize the spline specifications according to our requirements?
    Yes, we offer fully customizable spline shafts with tailored parameters including module (M), number of teeth (Z), pressure angle (α), and lead angle. Our manufacturing process is designed to accommodate your specific application needs.
  • What applications are these spline shafts suitable for?
    Our custom spline shafts are designed for both linear and rotary drive applications where torque transmission and anti-rotation capabilities are required. They provide superior performance in applications involving bearings, bores, gears, and bushings.
