Tungsten Carbide Cylinder Bushing Sleeve
The Tungsten Carbide Cylinder Bushing Sleeve is a wear‑resistant component produced by Sichuan Burray Cemented Carbide Co., Ltd. It is made from cemented carbide (WC‑Co) using high‑purity ultra‑fine powder processed through tilt ball milling and vacuum stirring. The sleeve is precision‑pressed, digitally degreased, sintered under pressure and finished with post‑processing to achieve tight dimensional control.
The resulting alloy exhibits typical hardness above 1500 HV and typical compressive strength exceeding 3000 MPa, making it substantially harder than conventional steel. Grain size is typically 0.5‑1 µm, giving a fine microstructure that resists galling in high‑load environments. Industry standards often require tolerance on outer diameter of ±0.01 mm and density around 14.5 g/cm³, which this product meets through the described powder‑metallurgy route. Typical operating temperature limits are up to 600 °C, after which carbide oxidation may begin.
These sleeves are widely used in oil‑field valve assemblies, mining pump shafts and precision mechanical engineering applications where long service life is critical. Importers should confirm the exact inner and outer diameters required for their equipment and request a material test report confirming hardness and composition. Trade discussions should include packaging format, such as individual sleeves in anti‑corrosive bags, and agreed Incoterms, while payment terms are negotiated directly with the supplier.

Sourcing Tungsten Carbide Cylinder Bushing Sleeve from Sichuan Burray Cemented Carbide Co., Ltd. - China Import Guide
Before placing an order, importers should verify the exact inner and outer diameters required for their machinery and request a material test report that confirms hardness, composition and density. It is also advisable to obtain the supplier’s latest ISO 9001 certificate and any other quality‑system documentation that the buyer deems necessary for compliance with internal standards.
Logistics for this product typically involve sea freight from the port of Zigong or nearby Shanghai, although the exact port should be confirmed with the supplier. Buyers need to agree on Incoterms such as FOB or CIF, clarify lead‑time expectations and negotiate payment terms, which are commonly structured as a deposit on order and balance upon shipment. Because response times are currently unrecorded, early communication is essential to lock in shipping schedules.
Quality assurance can be enhanced by arranging a third‑party pre‑shipment inspection that checks dimensional tolerance, surface finish and material hardness. Importers should also request a certificate of conformity and a packing list that details the anti‑corrosive packaging used. Maintaining records of these documents will facilitate customs clearance and downstream quality control procedures.
