Drive Shaft

A: Yes. We support precise OE-number cross-referencing. Our engineering team verifies fitment using vehicle make, model, year, critical mounting dimensions, technical drawings, or physical samples.

A: Vibration control is critical for driveline performance and service life. Every finished assembly undergoes 100% dynamic balancing according to the specified ISO 1940 G6.3 / G16 balance grade, while total shaft runout is controlled to ≤0.05 mm where specified.

A: Material and heat treatment are selected according to operating stress and wear requirements. 42CrMo alloy steel is suitable for high-torque and heavy-impact applications with quenched-and-tempered or induction-hardened treatment; 20CrMnTi is used for wear-loaded splines and yokes with carburizing to HRC 58–62; SUS304 stainless steel is available for corrosive or specialty environments.

A: Yes. We support reverse engineering and ODM development based on physical samples or 2D/3D drawings. Engineering review can include dimensional verification, material spectroscopy, critical interface analysis, and prototype fabrication.

A: We support customization of overall shaft length (OAL), tube outer diameter and wall thickness, spline tooth count and pitch, flange bolt patterns, universal joint specifications, and integrated center support bearings according to application requirements.

A: For selected stock OE models, trial orders can start from 4 pieces. For custom ODM or private-label production, MOQ depends on part complexity, tooling requirements, material selection, and production volume.

A: Selected in-stock models typically ship within 1–7 days after order confirmation. Custom and mass-production orders typically require 25–35 days, depending on tooling, raw material preparation, product configuration, and order quantity.

A: Yes. We support private-label programs with laser etching for brand names and OE numbers, customized barcode labels, individual product packaging, VCI anti-rust protection, and export cartons or palletized packaging.

A: We provide a standard 6-month to 1-year quality warranty, depending on application and agreed supply terms. Coverage addresses manufacturing defects, weld-related structural failures, and qualifying dynamic imbalance issues.
