Carbide Bearings Sleeves
Carbide bearing sleeves from Zhuzhou Tongda Cemented Carbide are precision wear components made from tungsten carbide (WC-Co), designed for stamping, drawing and metal forming machinery where they serve as protective guides and bushings. The sleeves feature outer diameters ranging from 6 to 450 mm, inner diameters from 8 to 400 mm, and heights from 2 to 225 mm, with bore and cylindrical surfaces finished to high dimensional accuracy for consistent performance under load. Their primary role is to reduce friction between moving parts, protecting both the punch and the bearing while maintaining alignment during high-frequency operations.
The material composition, tungsten carbide with cobalt binder, delivers exceptional hardness (typically 88-92 HRA), wear resistance and thermal stability, making these sleeves suitable for high-pressure, high-temperature environments common in automotive, tool fabrication and heavy machinery applications. Standard surface finishes for the bore and outer diameter are mirror-like to minimise friction and extend service life, while the low coefficient of thermal expansion helps maintain tight tolerances during temperature fluctuations. These properties also contribute to corrosion resistance, which is critical in pumps and other fluid-handling systems where the sleeves are frequently deployed.
Industries such as metal stamping, copper and stainless steel drawing, and pump manufacturing rely on these sleeves to prevent premature wear, maintain product dimensional accuracy and reduce downtime for replacement. The sleeves are typically supplied in bulk packaging for industrial use, with custom dimensions available to match specific machinery requirements. Buyers should confirm compatibility with their equipment’s load, temperature and velocity parameters to ensure optimal performance and longevity.

Sourcing Carbide Bearings Sleeves from Zhuzhou Tongda Cemented Carbide Co., Ltd. - China Import Guide
Before placing an order, verify that the sleeve dimensions (outer diameter, inner diameter, height) and tolerances match your machinery’s specifications, as mismatches can lead to premature wear or operational failures. Confirm the material grade of the tungsten carbide, as different cobalt contents can affect hardness, corrosion resistance, and suitability for specific applications such as high-pressure pumps or metal forming.
Discuss logistics details such as lead time, which may vary depending on custom dimensions or bulk quantities, and clarify the Incoterms (e.g., FOB, CIF) to determine responsibility for shipping and insurance costs. Payment terms should also be agreed upon in advance, with common options including TT (Telegraphic Transfer) or LC (Letter of Credit) for international transactions. Packaging standards for bulk shipments should be confirmed to ensure the sleeves arrive undamaged and ready for immediate use.
Request quality inspection documentation, including hardness test reports (HRA), surface finish measurements, and dimensional accuracy certificates, to ensure the sleeves meet the specified tolerances. For applications involving corrosion-resistant or high-pressure pumps, ask for additional testing such as salt spray resistance or pressure endurance tests. Conduct a first-article inspection upon receipt to verify that the sleeves perform as expected in your specific machinery, and establish a protocol for periodic checks to monitor wear and replace components before they fail.
