Seamless Bearing Steel Tubes
Energy Steel Industrial Co., Ltd. supplies seamless bearing steel tubes that are machined from high‑carbon chromium alloys. The tubes are offered in outer diameters ranging from 5 mm to 100 mm and wall thicknesses from 1 mm to 25 mm. Material grades include 100Cr6, GCr15, SUJ2 and 52100, all conforming to the listed specifications. These dimensions and grades are stated in the supplier’s catalogue.
The alloys meet DIN 17230, ASTM A295, ASTM A534 and JIS G 4805 standards, which are the common benchmarks for bearing components. Typical heat treatment involves annealing followed by hardening and tempering to achieve a hardness of 58 - 62 HRC. In the bearing industry, such tubes are recognised for tensile strengths between 800 and 1100 MPa. Surface finish is usually milled to a roughness of Ra 0.2 µm, matching the requirements of precision assemblies.
These tubes are used as bearing rings and bearing shafts in automotive gearboxes, industrial machinery and aerospace subsystems. Importers in North America, Europe and the Asia‑Pacific region commonly source them for high‑performance mechanical assemblies. Buyers should confirm the exact grade, dimensional tolerance and trade terms such as FOB or CIF with the supplier before placing an order.

Sourcing Seamless Bearing Steel Tubes from Energy Steel Industrial Co., Ltd. - China Import Guide
Before confirming an order, verify the exact steel grade, outer‑diameter range and wall‑thickness tolerance required for your bearing design. Ask the supplier for mill test certificates and any third‑party inspection reports that reference DIN 17230 or ASTM A295 compliance. Confirm that the product packaging meets your handling and transport preferences.
Discuss logistics early: clarify whether the shipment will be on FOB, CIF or another Incoterm, and request an estimated lead time based on the current production schedule. Payment terms such as T/T, L/C or open account should be negotiated directly with the supplier and documented in the sales contract. Ensure that all agreed terms are reflected in a written purchase order.
Arrange for quality assurance by planning a pre‑shipment inspection or full‑scale testing at the supplier’s facility. Standard checks include hardness measurement, tensile testing and dimensional verification, with results documented in a final inspection report. Request that the supplier provides a material test report, heat‑treatment certificate and compliance declaration for the relevant standards.
