The Four Row Tapered Roller Bearing model 382968 is a multi‑row bearing designed for heavy‑duty industrial machinery. It features an inner diameter of 340 mm, an outer diameter of 460 mm and a width of 310 mm. The bearing is manufactured from high‑carbon chromium bearing steel (GCr15, equivalent to AISI 52100) and incorporates a 4 mm chamfer on the inner race. Its basic dynamic load rating is 2100 kN, static load rating 8140 kN, and the limited speed is 367 rpm when greased or 482 rpm with oil lubrication, with a gross weight of 147 kg.
This steel grade provides a hardness typically between 60 and 66 HRC, giving the bearing excellent fatigue resistance under high radial and axial loads. In the bearing industry, four‑row tapered designs are recognised for handling simultaneous high thrust and radial forces, a capability that exceeds that of double‑row counterparts. Typical operating temperature for GCr15 bearings ranges from - 40 °C to +150 °C, and standard tolerance class for such dimensions is P5, ensuring interchangeability in rolling‑mill applications. Cojinete Bearings can also supply sealed variants of tapered roller bearings when required.
The bearing is commonly used in rolling mills, mining crushers, cement kilns and power‑generation gearboxes, where reliability is critical for continuous operation. Importers should confirm the exact MOQ, lead time and preferred Incoterms directly with Cojinete Bearings, as the listing does not disclose these trade details. Shipping is typically arranged by sea freight from the Dalian industrial park, and payment terms are negotiated per order.

Before placing an order for the 382968 bearing, importers should verify the exact dimensions (inner, outer, width) against the technical drawing, confirm the material grade GCr15 and request the mill test certificate, and ensure the dynamic and static load ratings meet the requirements of the target equipment. It is also prudent to ask for the bearing’s tolerance class and any surface‑finish specifications that affect shaft fit. Any deviation from the listed specifications should be documented and approved before shipment.
Shipping of the bearings is normally arranged from the Dalian industrial park via sea freight, but the precise lead time depends on the production schedule and the chosen Incoterm. Buyers should discuss whether the supplier can accommodate FOB, CIF or DAP terms and clarify the port of discharge. Payment methods such as T/T in advance, letter of credit or open account are negotiated per transaction, and the final agreement should be recorded in the purchase contract.
For quality assurance, importers are advised to schedule a third‑party inspection before loading, focusing on dimensional conformity, hardness testing and surface integrity of the bearing races. Request the supplier’s ISO‑9001 certification or any relevant quality system documents, as well as the batch test report for the specific lot. Upon arrival, a receipt inspection should verify the gross weight, packaging condition and the presence of the required certificates before acceptance.
