About Arya Guan - Bearing Supplier in China

China‑based Arya Guan lists 51 active products, all concentrated in bearing‑related categories. The catalogue spans deep‑groove ball bearings, pillow block bearing housings, spherical roller bearings and specialized concrete‑plant bearings, each identified by HS‑code families such as 8482.10 for ball bearings, 8483.20 for pillow block housings, 8482.30 for spherical rollers, 8482.40 for bore housings, 8482.80 for U‑groove units and 8483.40 for pressed‑steel housings. Materials are repeatedly noted as GCR 15 high‑carbon chromium steel, often referenced as GCr15 or 52100, with stainless‑steel variants such as AISI 440C or 304. The product titles include precise dimensions (e.g., 30 mm pillow block, 15 × 24 × 5 mm ball bearing) and clearance codes (ZZ, 2RS, C3).

Product Range and Specialties of Arya Guan

Arya Guan’s catalogue contains standard deep‑groove ball bearings ranging from size 6001 to 6317, pillow block units in 30 mm bore sizes, and heavy‑capacity spherical roller bearings for railway applications. In the bearing industry, deep‑groove balls are typically supplied to ISO 1993 tolerances, with C3 radial clearance for high‑speed service and hardness values of 58‑62 HRC on GCr15 steel. Stainless‑steel variants (AISI 440C, 304) meet corrosion‑resistance specifications required in food‑processing or marine environments. Pillow block housings are commonly cast in ductile iron or machined from GCr15 steel and shipped with sealed steel shields to protect against dust and moisture. Spherical roller bearings for rail use are graded to dynamic load ratings of 120 kN  -  180 kN, conforming to ISO 281 for fatigue life calculations.

Trade and Export Information - Arya Guan

China is one of the world’s largest exporters of rolling‑element bearings, supplying automotive OEMs, construction equipment makers and rail system manufacturers across Europe, North America and Southeast Asia. HS‑code 8482.10 covers most deep‑groove ball bearings, while 8483.20 and 8483.30 are used for pillow block housings and related components; customs inspections frequently verify material certificates and compliance with ISO 9001 quality‑management systems. Buyers typically request CE marking or equivalent conformity documentation for equipment that enters the EU market, and may also require ISO 14001 environmental certification from Chinese suppliers. Standard packaging includes steel drums or wooden crates, loaded into 20‑ft or 40‑ft containers, with FOB Shanghai or CIF destination as common Incoterms. Export logistics from Chinese ports benefit from established rail and sea corridors, enabling lead times of 20‑35 days to major ports in the United States, Germany and Japan.

Sourcing from Arya Guan - Buyer Guidance

When sourcing bearings from Arya Guan, request a mill test certificate that confirms GCr15 chemical composition, hardness (58‑62 HRC) and dimensional tolerance class. Verify that the supplier can provide ISO 9001 certification and, for stainless‑steel items, a passivation report meeting ASTM A240 standards. Buyers should also ask for a dynamic load‑rating test report (ISO 281) and confirm the clearance code (e.g., C3, ZZ) matches the intended application. Sample orders of a few units are advisable to assess fit and runout before committing to larger volumes, and the supplier should supply a packing list indicating container load plan and any anti‑corrosion coating used on housings.

What bearing types are included in Arya Guan’s product list?

The catalogue covers deep‑groove ball bearings (e.g., 6001‑6317 series), pillow block bearings and housings, spherical roller bearings for railway use, and concrete‑plant bearings for construction machinery.

Which HS codes apply to the listed bearings?

Ball bearings fall under HS 8482.10, pillow block housings under 8483.20 or 8483.30, spherical roller bearings under 8482.30, bore housings under 8482.40 and U‑groove units under 8482.80.

What materials are used for the steel components?

Materials are specified as GCR 15 high‑carbon chromium steel (equivalent to GCr15/52100) and stainless‑steel variants such as AISI 440C or 304, both common in bearing manufacture for strength and corrosion resistance.

Which certifications should a buyer verify before purchase?

Buyers should request ISO 9001 quality‑management certification, ISO 14001 environmental compliance if required, and material test certificates confirming GCr15 composition and hardness. CE marking may be needed for EU‑bound equipment.

How are the bearings typically packaged for export?

Bearings are usually packed in sealed steel drums or wooden crates, with protective grease applied to the inner rings. Loads are arranged in 20‑ft or 40‑ft containers, often under FOB Shanghai or CIF terms.

What are typical minimum order quantities and lead times?

Minimum order quantities range from 100 units for standard ball bearings to 500 units for larger pillow block assemblies. Lead times are generally 20‑35 days from order confirmation, depending on product complexity and shipping destination.

How can a buyer request a sample or test report?

Buyers should contact the supplier with a written request specifying the bearing size, material grade and required test (e.g., hardness, load rating). The supplier will then provide a mill test certificate and, if needed, a functional test report before shipment.

Which markets commonly import these types of bearings?

Key import regions include Europe (automotive and rail sectors), North America (construction equipment), and Southeast Asia (machinery manufacturing). These markets typically require compliance with ISO standards and documented material certifications.
