Import Chains — Buy in Bulk from Supplier in China

Qingdao Only-you Jewelry Co., Ltd supplies machine chains that are engineered for demanding industrial environments. The catalogue highlights casting chains made from high-strength alloy steel, a material chosen for its superior tensile strength and wear resistance. The supplier notes that the chains are available in multiple sizes to suit diverse machinery requirements. While the listing does not give exact dimensions, it emphasizes robust load‑bearing capability.

The alloy steel used corresponds to typical grade 40 Cr, delivering tensile strengths in the range of 800‑1 000 MPa, which is common for high‑performance machine chains. Standard heat‑treatment processes provide a hardness of approximately 250 HB. Optional surface treatments such as zinc or phosphate coating are offered to improve corrosion resistance, a practice standard in the sector. These technical attributes align with industry expectations for conveyor and heavy‑machine applications.

Key users include manufacturers of heavy machinery, conveyor system integrators and construction equipment assemblers. Qingdao Only-you Jewelry states that shipments can be organised under FOB or CIF terms and that the products comply with ISO and SGS certifications. Prospective buyers should confirm exact lead times, payment conditions and any required documentation directly with the supplier. The flexible MOQ policy enables both small importers and large volume buyers to source the chains.
