About Shandong JFZ Bearing Co., Ltd. - Bearing Supplier in China

China hosts 25 active product listings from Shandong JFZ Bearing Co., Ltd., all classified under the bearing category. The catalogue consists of cylindrical roller bearings identified by the RHP MRJ series, with model designations such as 7/8, 1.3/8, 3, and 5, each linked to HS codes 8482.40 or 8482.50. Materials cited include high‑carbon chromium steel (GCr15), chrome steel (AISI 52100), and bearing steel variants (SUJ2), with some units featuring steel or brass cages. The supplier’s product list therefore covers a range of size fractions and cage configurations while remaining within the two HS‑code families for roller bearings.

The product names follow a systematic pattern that indicates size fractions (for example 1.1/2 represents a 0.5 inch bore) and cage type (brass‑caged or steel‑caged). All 25 SKUs are cylindrical roller bearings, a type commonly used in heavy‑duty shafts, gearboxes and industrial machinery. By referencing the HS codes and material grades, the catalogue provides clear technical identifiers for each bearing without additional marketing language.

Product Range and Specialties of Shandong JFZ Bearing Co., Ltd.

Cylindrical roller bearings are defined by their ability to support high radial loads and are typically supplied in ISO series 15, 20, 30, or 40, depending on load capacity. The material grades shown in the catalogue - GCr15, AISI 52100, and SUJ2 - are the standard high‑carbon chromium steels used worldwide for such bearings, offering hardness levels around 60‑65 HRC. Cage options include machined steel, stamped steel, or brass, which affect noise and temperature performance. Common dimensions for the RHP MRJ series range from bore diameters of 5 mm up to 125 mm, with outer diameters and widths proportional to the size fraction. Buyers often specify clearance classes C3 (standard) or C4 (greater) and dynamic load ratings (C) that align with the intended application.

Industry practice also dictates that cylindrical roller bearings be supplied with lubrication pre‑filled or oil‑treated sleeves, and that technical data sheets list bearing number, bore, outer diameter, width, static and dynamic load ratings, and recommended operating temperature. The supplier’s catalogue aligns with these norms by providing the core material and cage type for each SKU, enabling buyers to match specifications to their equipment requirements.

Trade and Export Information - Shandong JFZ Bearing Co., Ltd.

China is one of the world’s largest exporters of rolling‑element bearings, supplying automotive manufacturers, heavy‑equipment makers, and general industrial users across Europe, North America, and Southeast Asia. The HS‑code 8482.40 covers roller bearings with steel cages, while 8482.50 includes bearings with alternative cage materials or configurations, both of which are routinely inspected under customs regimes that may request material test certificates and conformity declarations. Typical certifications requested by importers are ISO 9001 quality‑management, ISO 14001 environmental management, CE marking for EU markets, and RoHS compliance for electronics‑related applications. Export shipments are commonly packed in anti‑corrosion oil‑treated sleeves, placed in wooden crates or bulk bags, and loaded in 20‑ft or 40‑ft containers under FOB Shanghai or CIF destination terms.

Buyers of Chinese cylindrical roller bearings usually target sectors such as automotive drivetrains, construction machinery, wind‑turbine gearboxes, and material‑handling equipment. The logistics chain often involves container freight forwarding, with customs authorities checking the HS classification, country of origin marking, and accompanying test reports. Chinese bearing manufacturers benefit from established port facilities in Qingdao, Tianjin and Shanghai, which handle high volumes of HS 8482 shipments each year.

Sourcing from Shandong JFZ Bearing Co., Ltd. - Buyer Guidance

When sourcing cylindrical roller bearings from this supplier, request a material test certificate that confirms the chemical composition of GCr15, AISI 52100 or SUJ2 steel, as well as hardness and tensile strength values. Ask for a technical data sheet that lists bore size, outer diameter, width, dynamic load rating (C), static load rating (C0), and the clearance class (C3 or C4) for each RHP MRJ model. Verify the cage material - steel or brass - matches the performance requirements of the intended application, and confirm that packaging includes oil‑treated sleeves and sturdy export crates.

It is advisable to obtain a sample bearing before committing to a full order, especially to assess dimensional accuracy and noise characteristics. Ensure that the HS code on the commercial invoice aligns with the product’s cage type (8482.40 for steel‑caged, 8482.50 for other cages) to avoid customs delays. Finally, confirm the supplier’s compliance with any required certifications such as ISO 9001 or CE, and retain the test reports for quality‑control audits.

What types of cylindrical roller bearings are listed in the catalogue?

The supplier lists 25 SKUs of cylindrical roller bearings under the RHP MRJ series, covering size fractions from 1/8 inch up to 5 inches. Each model is identified with either HS code 8482.40 or 8482.50 and is made from high‑carbon chromium steel grades such as GCr15, AISI 52100 or SUJ2.

Which material grades are used for the bearing rings?

The catalogue specifies high‑carbon chromium steel (GCr15), chrome steel (AISI 52100) and bearing steel (SUJ2) as the primary ring materials. These grades are standard worldwide for high‑load cylindrical roller bearings and provide hardness levels around 60‑65 HRC.

What cage materials are available for these bearings?

Cage options mentioned include machined steel cages, stamped steel cages, and brass cages. The cage material influences operating temperature, noise and lubrication retention, and is reflected in the product description (e.g., "with machined brass cage").

How are the bearings packaged for export?

Typical export packaging for Chinese cylindrical roller bearings involves oil‑treated sleeves placed in wooden crates or bulk bags. The crates are loaded into 20‑ft or 40‑ft containers under FOB or CIF terms, with the HS code clearly indicated on the commercial invoice.

Which certifications should a buyer request from the supplier?

Buyers should request an ISO 9001 quality‑management certificate, material test certificates for the steel grades, and, where required by the destination market, CE or RoHS compliance documentation. These documents are commonly required for bearing imports.

What HS codes apply to the listed bearings?

Products with steel cages are classified under HS code 8482.40, while those with alternative cage materials such as brass or unspecified cages fall under HS code 8482.50. The correct HS code is indicated for each SKU in the catalogue.

What is the typical lead time for an order?

Standard lead times for Chinese cylindrical roller bearings range from 15 to 30 days after order confirmation, depending on order size and packaging requirements. Larger bulk orders may require additional production scheduling.

What clearance classes are commonly supplied?

Cylindrical roller bearings are usually supplied in clearance class C3 (standard) and C4 (greater) to accommodate higher thermal expansion in heavy‑duty applications. Buyers should verify the required clearance class on the technical data sheet.
