| Application and load definition | Supplier confirms rated load, stroke, mounting, duty cycle, side-load conditions, and operating environment before proposing a design. | Reviewed technical questionnaire, load calculations, and a dimensioned drawing. | A cylinder must be selected for the machine’s actual load path and operating conditions; nominal thrust alone does not describe the full application. | 20% |
| Design and engineering capability | Can engineer the required bore, rod, stroke, end fittings, seals, ports, and installation envelope; flags buckling and side-load risks where relevant. | Calculation assumptions, CAD drawing, material specifications, and documented design-change process. | Correct sizing and mounting details help prevent instability, premature wear, and fit-up problems. | 15% |
| Pressure and safety specification | Working pressure, proof-test pressure, and any applicable machine or industry requirements are clearly stated for the exact model. | Model-specific datasheet, test procedure, and test records identifying the acceptance criteria. | Pressure ratings and test requirements vary by design and application; they should be verified rather than inferred from a general catalogue. | 15% |
| Materials and manufacturing controls | Supplier defines materials and finishes for the tube, rod, seals, and corrosion protection, with traceable inspection controls. | Material certificates where specified, inspection plan, critical-dimension records, and coating details. | Material and surface choices affect strength, wear, corrosion resistance, and service life in the intended environment. | 15% |
| Quality assurance and testing | Inspection and functional testing are defined for the ordered configuration, including leak checks and dimensional verification as applicable. | Sample inspection report, test certificate, calibration records, and a clear nonconformance process. | Documented checks provide evidence that the delivered cylinder meets the agreed specification. | 15% |
| Customization and production readiness | Can accommodate required dimensions, interfaces, seal options, and approved drawing revisions; production lead time is stated by order quantity. | Prototype plan, confirmed production schedule, change-control records, and packaging details. | Lifting equipment often uses application-specific interfaces, so configuration control and realistic scheduling matter. | 10% |
| Service, spare parts, and warranty | Warranty scope, response process, spare-seal availability, and after-sales responsibilities are provided in writing. | Written warranty terms, spare-parts list, service contact process, and stated exclusions. | Clear support arrangements can reduce downtime and clarify responsibilities if a problem occurs. | 5% |
| Total cost and delivery terms | Quotation separates cylinder configuration, testing, packaging, freight, and any tooling or sample charges; delivery terms are explicit. | Itemized quotation, Incoterms® rule and named place, payment terms, and validity period. | A comparable landed-cost view helps avoid choosing solely on unit price while overlooking scope or logistics. | 5% |
