Tungsten Carbide Ball Bearing
Chengdu Woco Carbide Industry Co., Ltd. produces tungsten carbide ball bearings in China using a sintered WC‑Co or WC‑Ni matrix. The material combines tungsten carbide (WC) with a cobalt (Co) or nickel (Ni) binder and is processed by high‑temperature sintering to achieve a dense, wear‑resistant component. The supplier indicates that the bearings are suitable for oil‑ and gas‑valve seats, high‑speed machinery and corrosive chemical processing where conventional steel bearings fail. Export is handled worldwide with standard industrial packaging.
Typical hardness for the sintered carbide reaches 1,400 HV, providing the durability required for extreme operating conditions. Ball diameters are commonly offered from 2 mm up to 30 mm, with dimensional tolerances of ±0.001 mm (standard) and a surface finish of Ra 0.2 µm (typical). These specifications enable high‑speed rotation and maintain sealing integrity under high temperature and pressure. The product is frequently supplied as individual bearings or in bulk packs for assembly line integration.
Bulk orders are usually packed in wooden crates or sealed plastic bags, and pricing is quoted per piece. Buyers should confirm the exact ball size, tolerance class and any required coating or surface treatment with the supplier. Shipping terms are generally FOB unless otherwise arranged, and payment is negotiated per contract.

Sourcing Tungsten Carbide Ball Bearing from Chengdu Woco Carbide Industry Co., Ltd. - China Import Guide
When ordering, verify the exact ball diameter, tolerance class and binder composition required for your application. Request a material test report that includes hardness, density and surface finish data, and ask whether any additional coatings or heat‑treatment processes are applied. Confirm that the packaging meets your handling and storage needs, especially if long‑distance transport is involved.
Discuss logistics early by agreeing on an Incoterm, commonly FOB from a Chinese port such as Chengdu Inland Port or Shanghai, unless CIF is preferred. Typical lead times for standard sizes range from three to five weeks, with longer periods for custom dimensions or special treatments. Payment terms are usually negotiated as a 30 % advance by T/T with the balance payable against documents or after inspection, but adapt the terms to your risk profile.
Arrange for an independent third‑party inspection to verify dimensional accuracy, hardness and surface finish before shipment. Request certificates of conformity, a detailed test report and any relevant standard compliance documents to accompany the commercial invoice. Proper documentation and inspection will facilitate customs clearance and ensure the received bearings meet your technical specifications.
