Tungsten Carbide Bushings

Engineered for durability and precision, Retop’s tungsten carbide bushings provide superior wear resistance, shaft alignment, and corrosion protection in high-speed and abrasive environments.

Product Description

Tungsten carbide bushings are cylindrical components designed to protect shafts and housings in rotating and reciprocating equipment. Manufactured using high-hardness cemented carbide (WC-Co or WC-Ni), these bushings offer exceptional wear, erosion, and impact resistance. Retop provides a wide range of standard and custom carbide bushings—including straight, flanged, and split styles—with tight tolerance grinding to ensure accurate fit and minimal friction.

Carbide bushings are used extensively in centrifugal pumps, compressors, gearboxes, downhole tools, mud motors, turbines, and hydraulic systems. They serve as protective sleeves or guide elements for shafts operating under high-speed, high-pressure, and abrasive conditions—ideal for industries such as oil & gas, mining, chemical processing, water treatment, and marine engineering.
