Product RoleApplication Scenarios
These precision shafts are utilized in steering subsystems across a broad spectrum of modern road vehicles. We manufacture to customer-provided prints and serve the following segments:
● Volume-production sedan platforms
● Light truck and sport-utility configurations
● Full-electric and range-extended vehicle lines
● Advanced steering architectures for emerging powertrains

We do not engage in product design or engineering modification. Our function is strictly manufacturing-oriented: we receive customer drawings, conduct feasibility reviews against our equipment capabilities, and execute production runs that faithfully reproduce every feature specified on the print. Diameter tolerances, length constraints, spline or flat geometries, fillet radii, and finish requirements are all implemented as drawn. The 2µm roundness and 5µm runout values at journal sections are achieved through careful machine setup, tool selection, and real-time dimensional feedback, ensuring that outgoing parts conform exactly to customer expectations.
SummaryAutomotive Industry System
All work is performed within an IATF 16949-registered quality environment. Verification procedures include full print-dimension checks, form error measurement (roundness and runout), material property confirmation, and surface finish assessment. Each lot is released only after all criteria are met.
Ultimately, our EPS shaft offering represents manufacturing fidelity: we take customer designs and convert them into physical parts with consistent precision. This straightforward, drawing-compliant approach provides steering system manufacturers with a reliable source for this critical drivetrain component, regardless of whether the end application is internal combustion, hybrid, or battery-electric.
