We operate as a build-to-print manufacturing partner, executing EPS shaft production entirely according to client-provided specifications. Dimensional parameters including outer diameters, overall length, spline tooth profiles, undercut radii, and bearing journal placements are all realized per drawing requirements. Our production equipment and process controls are specifically calibrated to sustain tight tolerance regimes – holding roundness to 2µm and runout to 5µm as indicated on customer prints. This capability supports both large-scale OEM contract runs and smaller-batch specialized steering projects, with every shipment meeting defined print requirements.
SummaryAutomotive Industry System
All EPS shafts are produced within an IATF 16949-certified quality management framework. Each batch undergoes rigorous inspection routines prior to dispatch, covering dimensional metrology, geometry verification (roundness/runout), material hardness confirmation, and surface condition assessment – all benchmarked against the customer's original drawing specifications.
To conclude, our EPS motor shaft offering represents a blend of high-precision machining, strict drawing adherence, and comprehensive quality oversight, providing steering system suppliers with a dependable component solution for today's evolving vehicle platforms – from conventional internal combustion to fully electrified drivetrains.
