Product Description
Tungsten carbide bushings and sleeves are cylindrical wear-resistant components used to support and protect rotating shafts from friction, impact, and corrosion. Made from cemented carbide (WC-Co or WC-Ni), these bushings offer high hardness (HRA 89–92), excellent wear resistance, and long-lasting service life in harsh industrial environments. Retop offers both straight and stepped bushings with precise bore finishes and tight tolerances, available in various sizes and custom configurations.
Carbide bushings and sleeves are widely used in centrifugal pumps, submersible pumps, mud pumps, compressors, drilling stabilizers, hydraulic tools, and other rotating equipment. They are ideal for applications in oil & gas, mining, chemical processing, marine engineering, and high-pressure fluid systems where extended uptime and low maintenance are critical.
