Carbide bushings are precision-engineered wear-resistant components manufactured from tungsten carbide (cemented carbide). They are designed to protect shafts, housings, and rotating equipment from abrasion, corrosion, and high-pressure wear in demanding industrial environments.
Compared with conventional steel or alloy bushings, carbide bushings provide significantly longer service life, higher dimensional stability, and superior resistance to wear, making them the preferred choice for applications where reliability and durability are critical.
Zhuzhou Century Tool manufactures high-precision carbide bushings for the oil & gas, mining, pumps, valves, aerospace, chemical processing, and general engineering industries. Standard and custom OEM solutions are available according to customer drawings and specifications.
In severe operating conditions, conventional bushings often fail due to excessive wear or corrosion. Tungsten carbide bushings offer a longer-lasting and more cost-effective solution.
For high-load and high-speed applications, carbide bushings help maximize equipment performance while minimizing replacement frequency.
Manufactured from high-quality carbide grades to ensure excellent wear resistance and mechanical strength.
Advanced CNC machining and precision grinding guarantee:
Designed to withstand continuous abrasion from sand, slurry, drilling mud, and other highly abrasive media.
Suitable for applications involving corrosive chemicals, seawater, drilling fluids, and harsh industrial environments.
We produce carbide bushings in various sizes, shapes, and material grades based on customer requirements.
Zhuzhou Century Tool manufactures a wide range of carbide bushings, including:
Standard cylindrical bushings for general wear-resistant applications.

Zhuzhou Century Tool is an experienced manufacturer of precision tungsten carbide components with a strong focus on wear-resistant solutions.
Our advantages include:
Our goal is to provide reliable carbide bushings that help customers improve equipment efficiency and reduce total operating costs.
Carbide bushings are used to reduce wear between moving components in pumps, valves, drilling equipment, mining machinery, and other industrial systems operating under abrasive or high-load conditions.
Tungsten carbide bushings offer much higher hardness and wear resistance than steel, resulting in a service life that is typically 5–20 times longer, depending on the application.
Yes. Zhuzhou Century Tool manufactures custom carbide bushings based on customer drawings, dimensions, tolerance requirements, and application conditions.
Yes. Tungsten carbide bushings exhibit excellent corrosion resistance in many chemical processing, oil & gas, and marine environments. The exact performance depends on the carbide grade and binder composition.
Important considerations include shaft size, operating pressure, rotational speed, wear conditions, working temperature, corrosion environment, and required tolerances. Our engineering team can recommend the most suitable carbide grade and design.
