Tungsten Carbide Sleeve

Retop manufactures high-performance carbide sleeves engineered for extreme wear, corrosion, and thermal resistance in rotating equipment such as pumps, compressors, and drilling tools.

Product Description

Tungsten carbide sleeves are cylindrical protective components designed to support and shield rotating shafts from friction, fluid erosion, and abrasive wear. Manufactured from cemented carbide (typically WC-Co or WC-Ni), these sleeves offer outstanding hardness, chemical stability, and longevity in critical mechanical systems. Retop provides custom and standard carbide sleeves in both straight and stepped designs, ensuring precise fit and minimal clearance in high-performance assemblies.

Carbide sleeves are widely used in centrifugal pumps, submersible pumps, compressors, motors, gearboxes, mud tools, and downhole drilling systems. Their excellent resistance to slurry, seawater, oil-based fluids, and gas makes them indispensable in oil & gas, chemical processing, marine, mining, and power generation industries—especially in high-wear and high-load rotating conditions.
