Chongqing Sinounion Industries Inc manufactures crankshafts from high‑strength alloy steel for industrial and automotive use. The crankshafts are machined to precise dimensions to ensure compatibility with a broad selection of engine designs, and they undergo rigorous testing to meet international performance standards. The supplier highlights a focus on durability, vibration reduction and extended service life in heavy‑duty applications. Each shaft is classified under the appropriate HS code for mechanical components and is prepared for export.
Typical crankshafts in this segment have a length of about 300 mm, a main journal diameter near 70 mm and a weight in the range of 20 kg. Standard heat‑treatment processes such as induction hardening are applied to achieve surface hardness levels of 55 HRC, while core hardness remains around 30 HRC. Tolerances for journal diameter are usually ±0.02 mm, and surface roughness is kept within Ra 0.8 µm, meeting the expectations of most OEM specifications. These industry norms provide a benchmark for evaluating the supplier’s offering.
The crankshafts are targeted at manufacturers, repair workshops and equipment builders requiring reliable power transmission components. Chongqing Sinounion indicates that shipments can be arranged on FOB or CIF terms, with packaging in crates or pallets for safe transport. As the listed response rate is 0 %, interested buyers should request lead‑time, MOQ and any certification documents directly from the company. Confirming the alloy grade and heat‑treatment records will help ensure the shafts meet the intended application.

Sourcing Crankshafts from Chongqing Sinounion Industries Inc - China Import Guide
Before placing an order, verify that the alloy composition, heat‑treatment records and dimensional tolerances match the requirements of your engine design. Request a material test report or heat‑treatment certificate to substantiate the claimed strength and hardness levels. Confirm the outer dimensions, journal diameter and surface finish against the technical specifications of the target application to avoid fitment issues during assembly.
When planning logistics, ask whether the shipment will be on FOB or CIF terms and obtain the estimated departure date from the Chinese port. Because the listed response rate is zero, establish a clear point of contact for order confirmation, shipping documents and any customs clearance assistance. Clarify incoterm responsibilities, freight forwarder preferences and any insurance requirements prior to finalising the purchase.
Upon arrival, conduct a visual inspection for casting defects, surface cracks and dimensional accuracy. If possible, arrange a third‑party dimensional verification to ensure the length, journal diameter and tolerance meet the agreed specifications. Request the supplier’s material test report and heat‑treatment certificate to confirm compliance with the performance standards required for your machinery.
