About Luoyang Huayang Special Heavy Duty And Large Bearing Manufacturing Co., Ltd. - Bearing Supplier in China

Based in China, Luoyang Huayang Special Heavy Duty And Large Bearing Manufacturing Co., Ltd. currently lists five active products focused on heavy‑duty bearing solutions. The catalogue includes a LYHY four‑point contact ball slewing bearing, a thin‑section four‑point contact ball bearing, an LYHY triple‑row slewing bearing, an LYHY double‑row ball slewing bearing (HS 8483.60) made from bearing steel GCr15/52100, and an LYHY crossed‑roller slewing bearing (HS 8483.40.90) fabricated from alloy steel 42CrMo or carbon steel 50Mn. All items fall under the HS chapter 8483 for ball bearings and are positioned for large‑capacity, high‑load applications. The supplier’s product set reflects a focus on precision‑engineered rotary components for industrial machinery.

The listed bearings are classified as special heavy‑duty and large‑size units, suitable for crane turntables, wind‑turbine yaw systems, and heavy construction equipment. The four‑point contact designs provide combined radial and axial load capability, while the triple‑row and double‑row configurations increase load‑carrying capacity. Material specifications such as GCr15/52100 and 42CrMo meet the hardness and fatigue‑strength requirements typical for high‑speed, high‑load environments. No additional product categories beyond bearings are shown in the supplier’s current catalogue.

Product Range and Specialties of Luoyang Huayang Special Heavy Duty And Large Bearing Manufacturing Co., Ltd.

The supplier’s catalogue covers four‑point contact ball slewing bearings, thin‑section variants, triple‑row and double‑row ball slewing bearings, and crossed‑roller slewing bearings. In the bearing industry, four‑point contact designs are graded by dynamic load rating (C‑rating) and are often supplied in ISO 281‑based bearing numbers. Typical material grades include GCr15 (100Cr6) for high‑hardness ball bearings and alloy steels such as 42CrMo for crossed‑roller applications, both meeting Rockwell hardness HRC 60‑63.

Standard specifications for slewing bearings include ISO 1940/1941 vibration limits, IEC 60034‑2‑3 for efficiency, and tolerance classes from P0 to P5. Buyers usually request dimensions in millimetres, load capacities in kN, and speed limits expressed in rpm. The HS codes 8483.40 and 8483.60 correspond to roller and ball bearing assemblies, respectively, and are the common tariff headings for these products worldwide.

Trade and Export Information - Luoyang Huayang Special Heavy Duty And Large Bearing Manufacturing Co., Ltd.

China is one of the world’s largest exporters of heavy‑duty bearings, with the majority of shipments destined for North America, the European Union, and emerging markets such as India and Brazil. HS chapter 8483 covers ball and roller bearings, and the sub‑headings 8483.40 (ball bearings, other) and 8483.60 (ball bearing assemblies) are routinely examined under customs for anti‑dumping duties and safety inspections.

Typical importers require compliance with ISO 9001 quality‑management systems and, for automotive‑related bearings, ISO/TS 16949 certification. Additional documentation often includes a Material Test Report (MTR), a CE Declaration of Conformity for EU markets, and a customs‑friendly product description matching the HS code. Bearings are normally shipped in 20‑ft or 40‑ft containers, secured on wooden pallets, with moisture‑absorbing packs to prevent corrosion; FOB Shanghai or CIF major ports such as Ningbo are common incoterms.

Sourcing from Luoyang Huayang Special Heavy Duty And Large Bearing Manufacturing Co., Ltd. - Buyer Guidance

When sourcing from this supplier, buyers should request the material certification for GCr15/52100 or 42CrMo, along with hardness values (HRC 60‑63) and a load‑rating test report. Verification of dimensional drawings against ISO 286 tolerances and a vibration test according to ISO 1940 helps confirm suitability for high‑speed applications.

Samples are typically provided on a paid basis; the buyer should obtain a sample inspection report before confirming the full order. Confirm the packaging format (e.g., wooden crate with protective padding) and ensure the shipping terms (FOB or CIF) match the logistics plan. Checking that the supplier can issue a commercial invoice with the correct HS code and country of origin is essential for customs clearance.

What bearing types does the supplier offer?

The catalogue lists four‑point contact ball slewing bearings, thin‑section four‑point contact ball bearings, triple‑row slewing bearings, double‑row ball slewing bearings (HS 8483.60) and crossed‑roller slewing bearings (HS 8483.40.90). All are designed for heavy‑duty, large‑capacity applications.

Which material standards are used for the listed bearings?

The double‑row ball slewing bearing is made from bearing steel GCr15/52100, while the crossed‑roller slewing bearing uses alloy steel 42CrMo or carbon steel 50Mn. These materials comply with common bearing‑steel specifications for high hardness and fatigue resistance.

What HS codes apply to these products?

The double‑row ball slewing bearing is classified under HS 8483.60, and the crossed‑roller slewing bearing falls under HS 8483.40.90. The remaining bearing types are covered by the broader HS chapter 8483 for ball bearings.

Which certifications should a buyer request?

Buyers should request a material test certificate showing chemical composition and hardness, and a conformity report to ISO 1940 (rotating equipment) or ISO 9001 quality‑management certification if available. For automotive projects, ISO/TS 16949 may also be required.

What are typical packaging and shipping options?

Bearings are usually packed in wooden crates or steel drums with moisture‑absorbing packs, then loaded into 20‑ft or 40‑ft containers. FOB Shanghai or CIF major ports such as Ningbo are common incoterms used for shipment.

What is a typical minimum order and lead time?

Minimum orders often start at one set per bearing model, while larger projects may require multiples of 10 - 20 sets. Lead times reported by similar Chinese manufacturers range from 30 to 60 days after order confirmation and receipt of sample approval.

How can a buyer obtain samples?

Prospective buyers can request a pre‑shipment sample, which the supplier usually ships on a paid express basis together with a material certificate. Sample approval is a standard prerequisite before full production.

Which markets commonly import these bearings?

Major importers of Chinese heavy‑duty slewing bearings include the United States, Germany, India and Brazil, primarily for construction machinery, wind‑turbine gearboxes and marine applications.
