H7 Adjustment Ring
The H7 Adjustment Ring is a precision‑machined quartz sleeve that fine‑tunes the position of OSRAM H7 PX26D lamps. Fabricated from stainless steel SUS 430, the ring offers the durability required in vehicle headlamp assemblies. Its key dimensions are a height of 5.0 mm with a +0.1 mm tolerance, an outer diameter of 22.5 mm with a - 0.1 mm tolerance, an inner diameter of 15.0 mm with a +0.05 mm tolerance, and a wall thickness of 0.3 mm. The component has successfully passed an outgassing test, confirming its suitability for sealed lamp environments.
SUS 430 typically exhibits a hardness of around 190 HB and can be finished to a Ra 1.6 µm surface, which reduces friction during adjustment. In the lighting industry, adjustment rings are often subjected to a 3 % NaCl spray test for 72 hours to verify corrosion resistance, a standard that this material readily meets. The ring is produced using fully automatic progressive stamping equipment, ensuring consistent dimensional control across large batches. Visual inspection is performed on 100 % of the output, aiming for a defect‑free shipment.
The adjustment ring is incorporated by OEM lighting manufacturers and aftermarket distributors to achieve precise beam alignment in headlamp modules. Bulk packaging is 10,000 pieces per carton, allowing efficient palletisation for international freight. Importers should confirm the supplier’s minimum order quantity, lead‑time, and any required compliance documentation before placing an order.

Sourcing H7 Adjustment Ring from Zhejiang Invitech Precision Technology Co., Ltd - China Import Guide
When initiating a purchase, confirm that the SUS 430 material certification aligns with the specification and request a dimensional inspection report that records height, outer and inner diameters, and wall thickness. Verify that the ring’s outgassing test results are available and that the part complies with any OEM standards required for the OSRAM H7 lamp. Clarify the supplier’s minimum order quantity and any pre‑payment conditions before finalising the contract.
Discuss preferred Incoterms such as FOB Huzhou or CIF Shanghai and agree on an estimated lead‑time, as these details are not disclosed in the listing. Ensure that the supplier can accommodate your container loading plan and that any freight forwarder requirements are communicated early. Payment terms, including any letters of credit or advance payments, should be documented in the purchase agreement to avoid misunderstandings.
Quality assurance relies on the supplier’s 100 % visual inspection and the outgassing test; request copies of both certificates before shipment. Ask for a final inspection report that includes measurements of all critical dimensions to confirm compliance with the stated tolerances. Ensure that the commercial invoice, packing list and material safety data sheet accompany the goods for smooth customs clearance.
