The Eye Spring is a precision‑engineered tension component supplied by Nanjing Haofeng Surgical Product Co., Ltd. It is constructed from high‑grade steel that delivers excellent tensile strength and fatigue resistance. The design is machined to tight tolerances to ensure consistent performance in demanding mechanisms. The listing notes that the spring can be customized in size and specification to match project requirements.
High‑grade steel commonly corresponds to ASTM A228 music‑wire, which typically exhibits tensile strength around 2,100 MPa and an endurance limit near 1,000 MPa. Typical coil diameters for springs of this class range from 15 mm to 30 mm, with wire diameters between 1.5 mm and 3 mm, providing a spring rate around 150 N/mm. A polished surface finish is often applied to reduce friction and protect against corrosion. These characteristics make the eye spring suitable for repeat‑load applications.
The component is widely used in automotive suspension systems, aerospace actuators and general machinery where reliable tension is required. Nanjing Haofeng can supply the springs in bulk and offers flexible ordering options, though exact MOQ and lead‑time should be confirmed directly. Importers are advised to request material test reports and verify compliance with relevant standards before finalising the purchase.

Before placing an order, importers should verify the supplier’s business registration, request a recent factory audit report and obtain material test certificates for the steel grade. Confirm that the eye spring meets the required dimensions and mechanical properties for the intended application, and ask for a test report that includes tensile and fatigue data.
Logistics for shipments from Nanjing typically involve sea freight from the Port of Shanghai or Ningbo; buyers should agree on Incoterms such as FOB Shanghai or CIF Shanghai and clarify the expected lead‑time, which the supplier can provide after confirming order details. Payment terms commonly include T/T or L/C, but the exact schedule should be negotiated directly with the supplier.
Quality assurance should include pre‑shipment inspection according to the buyer’s inspection plan, sampling for tensile and fatigue testing, and verification of any ISO or SGS certificates. Retaining documented inspection reports and certificates will help smooth customs clearance and ensure the components meet project specifications.
