The Single Row Tapered Roller Bearing 30228 is a heavy‑duty bearing intended for high radial and axial load scenarios in industrial machines. It features an inner diameter of 140 mm, outer diameter of 250 mm and a width of 45.75 mm, with inner ring width of 42 mm and outer ring width of 36 mm. Its basic dynamic load rating is 439 kN and the basic static load rating is 627 kN, while the limited speeds are 1 512 rpm with grease and 2 090 rpm with oil lubrication. Each unit weighs 8.8 kg and is supplied in standard industrial packaging for container transport.
The bearing is manufactured from heat‑treated chrome steel, identified as GCr15/SUJ2, a grade commonly used for its hardness and wear resistance in demanding bearing applications. Industry practice typically applies an ABEC‑5 tolerance class to such dimensions, ensuring the required precision for vehicle wheel hubs and power transmission gearboxes. Chamfers of 4 mm on the cone and 3 mm on the cup are provided to aid assembly and minimise stress concentrations. Buyers may also select either clearance or preload mounting configurations to suit the equipment’s load profile.
Target users include OEMs and aftermarket distributors in the automotive, construction and heavy‑industry sectors that need reliable load support for wheel hubs or gear units. The listing does not disclose minimum order quantities, price or lead time, so prospective importers should request these details directly from the supplier. Confirmation of compliance with ISO or ABEC standards, along with a mill test certificate, should be obtained before finalising the purchase.

Located in the Wa Wo Town industrial zone of Dalian, Liaoning Province, China, Cojinete Bearings Co. Ltd. operates a manufacturing base close to the Port of Dalian, enabling efficient export of bearing components. The company holds a harbour‑level trust tier, indicating that its trade credentials have been vetted for international transactions.
According to the public profile the supplier’s response statistics show a 0 % response rate and no recorded response time, which suggests that communication may be limited. Cojinete Bearings advertises a catalogue of single‑row tapered roller bearings and provides standard industrial packaging, but leaves details such as MOQ, pricing and certification to be clarified through direct inquiry. Prospective buyers should therefore request specific trade terms and documentation directly from the supplier.
The 30228 is a single row tapered roller bearing with a 140mm bore, 250mm outer diameter, and 45.75mm width, designed for high radial and axial load applications in industrial machinery, vehicle wheel hubs, and power transmission systems. Constructed from high-grade chrome steel with precision-ground raceways, this bearing meets ISO and ABEC standards for dimensional accuracy and operational reliability. Widely sourced from major industrial hubs, it is a staple component in import-export trade for OEM and aftermarket supply chains across manufacturing, automotive, and construction sectors.

Importers should first confirm that bearing model 30228 meets the required tolerance class, typically ABEC‑5, and that the supplier can provide a current mill test certificate confirming the heat‑treated GCr15/SUJ2 composition. Request documentation of any heat‑treatment process and verify the dimensional drawings against the machine’s specifications. For critical applications, a sample or third‑party inspection report can add confidence before committing to volume.
The factory’s proximity to the Port of Dalian makes FOB Dalian a logical shipping term, though buyers may also negotiate CIF Shanghai depending on their logistics network. Because the public listing does not state lead time, the importer must ask the supplier for an estimated production and dispatch schedule. Payment arrangements such as T/T in advance or a confirmed L/C should be agreed upon before shipment.
To ensure product quality, arrange a pre‑shipment inspection covering dimensional accuracy, surface finish, hardness and verification of the load ratings. Inspections can be performed by an accredited third‑party agency either at the factory or upon arrival at the destination port. Collect the full set of documents - mill test certificate, conformity declaration, packing list and inspection report - to facilitate customs clearance and maintain traceability.
