Carbide blank shaft sleeves from Chongqing Henghui Precision Mold are semi-finished cemented carbide components made from 100 percent virgin tungsten carbide powder with a submicron grain structure and cobalt binder. The blanks are supplied in diameters from 25 mm to 500 mm, thicknesses from 8 mm to 30 mm, and lengths from 100 mm to 2000 mm, with a silver-grey metallic appearance and density typical for WC-Co grades. Each sleeve undergoes HIP sintering and precision grinding to achieve tight tolerances and a polished finish suitable for further machining into bearing or shaft protection parts.
The material composition delivers hardness and wear resistance that exceed standard steel alloys, with grades available from K20 to K50 to match varying impact and abrasion requirements. Submicron grain size enhances toughness, making these sleeves ideal for high-load applications in oil and gas drilling, mining equipment, and hydraulic systems. Virgin raw material ensures consistency in performance, while automatic pressing and advanced production equipment maintain uniform quality across batches.
These sleeves are used by OEMs and maintenance teams in heavy machinery sectors where extended service life and reduced downtime are critical. Buyers typically source them as blanks for custom machining into final components, with options for sintered or pre-processed supply states. Small orders and samples are accepted, allowing for prototyping and validation before bulk purchases.

Chongqing Henghui Precision Mold Co., Ltd. is based in Dragon Village, Baishiyi Town District, Chongqing, China, with a focus on precision carbide components for industrial applications. The company operates as an imported-tier supplier, utilising advanced production and testing equipment to manufacture semi-finished and finished carbide parts, including shaft sleeves, for global markets.
The supplier’s profile indicates a harbor trust tier, with no recorded response rate or average response time, suggesting limited engagement history on the platform. Their specialisation in carbide blanks, combined with capabilities in automatic pressing, HIP sintering, and precision grinding, positions them as a technical producer rather than a trading intermediary. Buyers are advised to confirm current response and verification status directly with the supplier.
Carbide blank shaft sleeves are semi-finished cemented carbide components designed for precision machining into wear-resistant bearing and shaft protection parts. Manufactured from virgin tungsten carbide powder with submicron grain structure, these blanks offer exceptional hardness, superior wear resistance, and dimensional stability under high-load mechanical stress. Widely used in oil and gas drilling, mining equipment, hydraulic systems, and industrial machinery, tungsten carbide shaft sleeves significantly extend component service life and reduce maintenance downtime. Available in multiple grades such as K20 through K50 to suit different impact and wear conditions, with precision grinding and polishing finishing options for OEM and replacement markets.

Before ordering, verify the exact grade of carbide (K20 to K50) and its suitability for your application’s impact and wear conditions. Confirm the supplier’s ability to provide material test reports (MTRs) or certificates of analysis (COAs) for the batch, as these documents validate the composition, purity, and mechanical properties of the blanks. Request samples for machining trials to assess dimensional stability and surface finish.
Discuss logistics details such as packaging, which should protect the sleeves from moisture and mechanical damage during transit. Standard packaging for carbide blanks includes wooden crates or foam-lined cartons, but confirm the supplier’s options. Lead times for custom sizes or grades may vary, so clarify production and delivery schedules, and agree on Incoterms (e.g., FOB Chongqing) and payment terms upfront.
Quality checks should include visual inspection for surface defects, dimensional verification using micrometers or calipers, and hardness testing with a Rockwell or Vickers tester. For critical applications, consider third-party inspection or non-destructive testing (NDT) methods like ultrasonic testing to detect internal flaws. Ensure all documentation, including test reports and compliance certificates, accompanies the shipment.
