About Sichuan Metalmiracle Industry Corp. - Bearing Supplier in China

Sichuan Metalmiracle Industry Corp. is based in Sichuan, China and lists five active products. The catalogue focuses on bearing solutions for industrial machinery, covering slewing bearings for general use, wind turbines, and trailer applications. Products are classified under HS chapters 8482 and 8483, with specific codes 8483.40 for standard slewing bearings and 8482.60 for wind‑turbine and general slewing bearing types. The company also offers a lycores slewing drive unit without a disclosed HS code.

The listed bearings employ Chrome Steel GCr15 (equivalent to 52100), alloy steels 42CrMo and 50Mn, and stainless variants such as 440C and 304, as indicated in the catalogue. Material specifications suggest suitability for high‑load and high‑speed applications typical of heavy‑duty rotating equipment. The product set includes both forged alloy steel constructions and machined steel components. The catalogue reflects a focus on bearing steel grades commonly required for precision load bearing.

Product Range and Specialties of Sichuan Metalmiracle Industry Corp.

The supplier’s range comprises three categories of slewing bearings: standard slewing bearings (HS 8483.40), wind‑turbine slewing bearings (HS 8482.60), and trailer slewing bearings (HS 8483.60). In the global market, slewing bearings are offered in ISO 1940/1941 classes such as C3, C4, and C5, with dynamic load ratings up to several hundred kilonewtons. Typical dimensions span bore diameters from 100 mm to 2000 mm and overall widths up to 300 mm. Common material grades include GCr15 (high‑carbon chromium steel), 42CrMo (alloy steel with good hardenability), and stainless 440C for corrosion‑resistant applications.

In addition to bearings, the catalogue lists a lycores slewing drive, a compact gear‑driven unit used to transmit torque in rotating platforms. Such drives are usually supplied as finished assemblies rated by torque capacity (e.g., 10 kNm to 200 kNm) and are packaged for easy integration into machinery. Buyers typically verify gear tooth profile, lubrication method, and bearing preload specifications.

Trade and Export Information - Sichuan Metalmiracle Industry Corp.

China is a major exporter of slewing bearings, with shipments directed to industrial hubs in Europe, North America, and Southeast Asia. HS codes 8482 and 8483 fall under Chapter 84, which is subject to customs inspections for compliance with safety and material standards. Importers frequently require conformity to ISO 9001 quality management systems, CE marking for EU markets, and, where applicable, ASTM or JIS standards for bearing performance.

Typical export packaging involves wooden crates or bulk pallets designed for 20‑ft or 40‑ft containers, with moisture‑barrier liners to protect steel surfaces. Incoterms such as FOB Shanghai or CIF Rotterdam are commonly used. Chinese manufacturers often provide pre‑shipment inspection reports prepared by third‑party agencies to meet buyer verification requirements.

Sourcing from Sichuan Metalmiracle Industry Corp. - Buyer Guidance

Prospective buyers should request material test certificates confirming chemical composition (e.g., carbon content for GCr15) and hardness values (HRC 58‑63). Dynamic and static load ratings, ISO 1940 class, and dimensional drawings are essential for engineering validation. Samples of the bearing steel or a trial unit can be requested before bulk orders, and buyers are advised to verify that the supplier can supply ISO 9001 certification or an equivalent quality audit report.

What bearing types are listed in the catalogue?

The catalogue lists standard slewing bearings, wind‑turbine slewing bearings, trailer slewing bearings, and a lycores slewing drive. Relevant HS codes are 8483.40, 8482.60, and 8483.60 where applicable.

Which steel grades are used in the bearings?

Materials specified include Chrome Steel GCr15/52100, alloy steels 42CrMo and 50Mn, and stainless steels 440C and 304. These grades are common for high‑load bearing applications.

What HS codes apply to these products?

Standard slewing bearings are classified under HS 8483.40, wind‑turbine and general slewing bearings under HS 8482.60, and trailer slewing bearings under HS 8483.60. The lycores slewing drive has no HS code listed.

Which certifications should a buyer verify?

Buyers typically ask for ISO 9001 quality management certification, CE marking for EU imports, and material test reports that meet ASTM A295 or equivalent standards.

How are the products packaged for export?

Products are usually packed in wooden crates or bulk pallets suitable for 20‑ft or 40‑ft containers, with protective coating to prevent corrosion during sea transport.

What documentation is needed for customs clearance?

A commercial invoice, packing list, certificate of origin, and any required test certificates (e.g., hardness, chemical composition) are standard for HS 84 categories.

What are typical lead times and minimum order quantities?

Lead times for custom‑size slewing bearings typically range from 30 to 60 days after order confirmation. Minimum orders often start at a single unit for prototype testing and scale up to container loads for mass production.
