About CIS Bearing Group Co., Ltd. - Bearing Supplier in China

CIS Bearing Group Co., Ltd. is based in China and currently lists five distinct bearing products in its catalogue. The portfolio includes deep‑groove ball bearings (series 6200, 6300, 6400) classified under HS code 8482.10, taper roller bearings under HS code 8482.20, spherical roller bearings under HS code 8482.30, toroidal roller bearings (CARB) under HS code 8482.50, and fork‑lit bearings also under HS code 8482.30. Each product is described with its primary material composition, ranging from chrome steel grades GCr15 and AISI 52100 to stainless steel 440C. The catalogue groups the items within the broader bearing category, which falls under Chapter 84 of the Harmonized System covering machine parts and accessories. No additional product families are listed beyond these five entries.

The deep‑groove ball bearings are offered in standard series sizes 6200, 6300 and 6400, a common dimension range used in electric motors and automotive applications. Taper roller bearings are presented as a single type without size breakdown, typical for supporting axial loads in gearboxes. Spherical roller bearings are specified as high‑grade chromium steel (GCr15/SUJ2) that has undergone vacuum degassing, a process aimed at improving fatigue strength. The toroidal (CARB) rollers are available in chrome steel 100Cr6 or AISI 52100, with an optional stainless steel 440C variant for corrosion‑resistant environments. Fork‑lit bearings are described as high‑carbon chromium bearing steel (GCr15/52100), a material frequently used for high‑speed shaft applications.

Product Range and Specialties of CIS Bearing Group Co., Ltd.

The catalogue’s deep‑groove ball bearing line (6200‑6400 series) corresponds to the internationally standard ISO 492 dimension series, where bore diameters run from 10 mm to 100 mm and outside diameters scale proportionally. In global trade, buyers often request dynamic load ratings (C rating) and static load ratings (C₀) expressed in kN, as well as precision grades such as ABEC‑1 to ABEC‑9 or ISO P0‑P6. The listed material GCr15 (Chinese equivalent of AISI 52100) and stainless steel 440C meet the typical hardness range of 58‑65 HRC for bearing steels. Taper roller bearings, identified under HS 8482.20, are usually supplied in the ISO 281/282 series with tapered bore and outer ring angles of 15° or 25°, and buyers assess them by the ISO 281 fatigue life equation.

Spherical roller bearings (HS 8482.30) are commonly offered in the 222‑224 series, featuring two rows of barrel‑shaped rollers and a tolerance class of P5‑P6. Toroidal (CARB) roller bearings, classified under HS 8482.50, are a specialized type used in high‑precision spindle applications; they are often produced to tolerance class P5 and may be supplied with stainless steel 440C cages for enhanced corrosion resistance. Fork‑lit bearings, also under HS 8482.30, are a niche variant employed in agricultural or construction equipment where a split‑ring design facilitates assembly; typical material specifications call for a carbon content of 1.0 %‑1.2 % and chromium 1.5 %‑2.0 % to achieve the required hardness.

Trade and Export Information - CIS Bearing Group Co., Ltd.

China is one of the world’s largest exporters of rolling‑element bearings, and products classified under HS chapter 84 - specifically codes 8482.10, 8482.20, 8482.30 and 8482.50 - are routinely shipped to automotive, industrial machinery and renewable‑energy sectors in Europe, North America and Southeast Asia. Buyers in Germany, the United States and Japan frequently source deep‑groove and spherical roller bearings for motor and wind‑turbine applications, while Southeast Asian manufacturers often import taper and toroidal rollers for textile and packaging equipment. Export shipments from China typically use the ports of Shanghai, Ningbo and Shenzhen, with freight consolidated in 20‑foot or 40‑foot containers depending on order volume. Customs authorities commonly require a commercial invoice, packing list and a certificate of origin for HS 8482 items; many importers also request a test report in accordance with ISO 9001 or an independent third‑party inspection certificate such as SGS or Bureau Veritas. For bearings destined for the European Union, CE marking and compliance with the Machinery Directive (2006/42/EC) are standard expectations, while North American buyers may ask for UL or ANSI standards documentation. Typical packaging includes anti‑corrosion oil‑treated bags placed in timber crates, with moisture barriers to preserve bearing integrity during sea transport. Incoterms such as FOB Shanghai or CIF Europe are frequently negotiated, allowing buyers to manage freight and insurance according to their supply‑chain preferences.

Sourcing from CIS Bearing Group Co., Ltd. - Buyer Guidance

When evaluating CIS Bearing Group’s offerings, buyers should request a material test report confirming the chemical composition and hardness (HRC) of the GCr15, 100Cr6 or 440C steels listed. A bearing performance test report based on ISO 281 fatigue life calculations and dynamic/static load ratings will help compare the supplied parts against design requirements. If precision is critical, ask for the ABEC or ISO P‑grade classification and a dimensional inspection certificate. Potential purchasers should also verify that the supplier can provide a copy of any applicable quality‑management certification (e.g., ISO 9001) and, for stainless‑steel variants, a corrosion‑resistance test report. Confirm packaging details - oil‑treated bags, moisture‑proof liners and crate dimensions - to ensure safe handling during transport. Finally, clarify the minimum order quantity, typical lead time (often 15‑30 days after order confirmation for standard sizes), and the preferred Incoterm for the transaction.
