Cojinete Bearings Co. Ltd. — Verified Supplier
About Cojinete Bearings Co. Ltd. - Bearing Supplier in China
China hosts Cojinete Bearings Co. Ltd., which lists 28 active bearing products in its catalogue. The items fall under the primary categories of Bearing and Agriculture and cover a spectrum of rolling‑element types such as spherical roller bearings, tapered roller bearings, cylindrical roller bearings, angular contact ball bearings and deep‑groove ball bearings. Each product is associated with an HS‑code in the 8482.xx range, for example 8482.10 for angular contact ball bearings and 8482.80 for tapered roller bearings, reflecting their classification under chapter 84 machinery and mechanical appliances.
The catalogue specifies materials mainly as Chrome Steel grades GCr15, 100Cr6 or AISI 52100, often combined with stamped steel cages or brass cages. Several entries note heat‑treated conditions or precision‑machined components, indicating compliance with typical bearing steel specifications. The product descriptions also include designations such as Cck30c3w33 or MBW33 that denote internal clearances and cage types commonly used in high‑load agricultural machinery.
Product Range and Specialties of Cojinete Bearings Co. Ltd.
The listed product line includes spherical roller bearings (e.g., 23072B, 23260MBW33) with internal clearance classes C3 and C4, four‑row cylindrical rollers (801669), single‑row tapered rollers (30228, 30226) and angular contact ball bearings (509098a). In the bearing industry, spherical roller bearings are frequently supplied in grades complying with ISO 281 life rating and ABEC‑type precision for heavy‑duty applications. Ball bearings such as the deep‑groove type 61856 are typically offered in ABEC 1‑5 series and may meet ISO 492 standard dimensions. Brass‑caged variants are preferred for corrosion‑resistant environments, while steel‑caged models are common in high‑speed drives. Typical bore sizes range from 10 mm to 200 mm, and load ratings are expressed in kN according to ISO 281 calculations.
Trade and Export Information - Cojinete Bearings Co. Ltd.
Exporters of bearings from China generally serve equipment manufacturers in Europe, North America, and Southeast Asia, especially sectors like agricultural machinery, construction, and mining. The HS‑code families 8482.10, 8482.20, 8482.30, 8482.40, 8482.50 and 8482.80 cover ball bearings, tapered rollers, spherical rollers, cylindrical rollers and related assemblies, and customs authorities often require conformity to ISO 9001 quality‑management systems and, where applicable, CE marking for EU markets. Buyers frequently request material test certificates showing hardness (typically HRC 58‑62) and chemical composition of GCr15 steel. Shipping is normally arranged in 20‑ft or 40‑ft containers with wooden crate packaging, using Incoterms such as FOB Shanghai or CIF destination port.
Sourcing from Cojinete Bearings Co. Ltd. - Buyer Guidance
When sourcing from Cojinete Bearings Co. Ltd., buyers should ask for a material test report confirming GCr15 composition and heat‑treatment details, as well as an ISO 281 life‑rating certificate. Verify the cage material (steel or brass) and internal clearance class (C3, C4) against the intended application. Typical minimum order quantities are around 100 units per bearing type, with a lead time of four to six weeks after order confirmation. Request a sample of a comparable bearing to validate dimensions, surface finish and noise performance before committing to larger volumes.
