Import Roll Shaft Bearing — Buy in wholesale FOB from Supplier in China

The roll shaft bearing supplied by Shaanxi Cfsm Sales & Engineering Co., Ltd. is a heavy‑duty component designed for coal grinding machines and mineral processing equipment. Each bearing is cast from ZG30Mn manganese cast steel using a sand‑casting process that provides good wear resistance. Units weigh between three and ten tonnes, matching the mass required to support large roller shafts in mining applications. The design integrates a bearing seat and a roller cover, allowing the shaft to be opened for maintenance without disassembly of the entire grinding train.

While the listing specifies a single material grade, the industry commonly offers ZG30Mn bearings in bore diameters from 500 mm to 2000 mm and outside diameters up to 2500 mm. Typical ISO 1940 class C load ratings range from 2000 kN to 15000 kN, suitable for the high torque conditions of mineral processing. Standard operating temperatures span - 30 °C to 200 °C, and surface roughness is usually finished to Ra 0.8 µm to minimise friction. Dimensional tolerances are generally held within ±0.05 % of the nominal size, and hardness is verified by Rockwell testing.

Primary buyers include manufacturers of coal grinding mills, power‑generation equipment suppliers, and original equipment manufacturers in the mining sector. The bearing is typically shipped as a single unit on a flat‑rack trailer, with the buyer arranging freight under a chosen Incoterm such as FOB or CIF. Because the listing does not disclose minimum order quantity, exact price or lead time, interested importers should request a formal quotation that includes these details. Confirm any required certifications, such as mill test reports or compliance with ISO 9001, before finalising the contract.

Shaanxi Cfsm Sales & Engineering Co., Ltd. is located at No.90 Electrionic 2Th Road, Yanta District, Xi'an, Shaanxi Province, China, as recorded in the supplier profile. The company holds a harbour‑level trust tier on the platform, but its response rate is currently shown as 0 % with no recorded response hours. This verification status indicates that while the business is listed, prospective buyers should seek direct communication to assess reliability. The address places the factory within a major industrial zone that supports heavy‑equipment manufacturing.

The supplier advertises roll shaft bearings made from ZG30Mn manganese cast steel, weighing between three and ten tonnes each. No information is provided regarding minimum order quantities, unit pricing, lead times, or specific quality certifications. Potential importers are advised to request detailed technical data sheets and mill test reports to confirm material properties. The listing does not mention any export experience or previous client references, so verification of past performance should be part of the due‑diligence process.
