A truck or trailer air spring enquiry becomes difficult when the photograph, part number and requested supply scope describe different things. YITAO AIR SPRING GROUP recommends preparing a clear RFQ package before comparing quotations. The objective is a shared understanding of the required component, rather than a quick price attached to an uncertain reference. This service guide explains what buyers can send and what still needs technical confirmation.
Keep the complete manufacturer marking, the vehicle reference and any earlier supplier number in separate fields. Preserve leading zeros, letters and suffixes. A label on an assembly and a marking moulded into the rubber can have different identification roles. If the label is missing, explain that limitation rather than filling the gap with a similar-looking catalogue number.
Send clear views of the upper plate, side profile and lower mounting area. Mark the connection that needs checking. A picture with an identified question is more useful than a collection of unlabelled images. Photographs support identification, but they do not establish thread size, approved installation height or engineering interchange by themselves.
State whether you need a complete assembly, a piston-free bellows section or another clearly identified component. Different supply scopes can explain different prices. Before comparing offers, check that the requested hardware and component level are consistent. Do not assume that a shared rubber profile means the upper and lower mounting arrangements are identical.
Where a connection or bracket remains uncertain, request the relevant drawing and confirm it against the application. The purchasing description should retain unresolved differences until they are checked. A catalogue reference is a search aid; final selection depends on the required configuration and the applicable technical approval.
Include quantity, destination port and the requested shipment window. Add packing, labelling or carton requirements when they affect the order. Ask the supplier to identify which conditions are confirmed and which remain subject to production scheduling. A general lead-time statement should not replace confirmation for the particular model and quantity.
Keep the approved quotation version with the final product identification. If the component scope changes, review packing and price again. This prevents a purchasing team from approving a complete assembly while another team prepares documents for a bellows-only supply. Clear records support consistent communication without promising a particular delivery outcome.
Can one photograph replace a drawing? No. It can show the general arrangement, while dimensions and connection details still require suitable evidence. Should a fault photograph be treated as a warranty decision? No. Inspection history, operating conditions and the actual damage must be reviewed separately.
For an air spring RFQ, accurate identification comes before confident commercial comparison. Send the available markings, labelled photographs and required component scope to YITAO AIR SPRING GROUP, together with your purchasing requirements. The next useful step is to resolve the specific uncertainty in the enquiry, not to add unrelated numbers to the description. This shared record helps subsequent review.
