Tungsten Carbide Bushings

Precision tungsten carbide bushings for pumps, valves, mechanical seals, rotating equipment, and wear-resistant guiding applications.

Product Overview

Tungsten Carbide Bushings are precision wear-resistant components used to support, guide, protect, and position rotating or reciprocating parts in demanding industrial equipment. Manufactured from cemented tungsten carbide, these bushings provide excellent wear resistance, high hardness, dimensional stability, and reliable performance under abrasive, high-pressure, and high-load operating conditions.

Carbide bushings are commonly used where conventional steel, bronze, or ceramic components may wear rapidly or lose dimensional accuracy. Their hard and stable working surfaces help reduce shaft wear, improve equipment reliability, and extend maintenance intervals in pumps, valves, mechanical seals, tooling systems, and other industrial assemblies.

KENIN Carbide manufactures standard and custom tungsten carbide bushings according to customer drawings, samples, operating media, mating components, tolerance requirements, and service conditions.

Applications

Tungsten carbide bushings are widely used in industrial equipment requiring long service life, wear resistance, and dimensional stability.

Typical applications include:

Pump shafts and pump wear parts
Mechanical seals and seal assemblies
Valve stems, valve guides, and flow-control components
Oil and gas equipment
Chemical process pumps
Mining slurry pumps and abrasive fluid handling equipment
Rotating machinery and bearing support systems
Tooling guides and precision positioning components
Steel processing and metalworking equipment
High-pressure and high-speed industrial machinery

Custom Manufacturing

KENIN Carbide manufactures custom tungsten carbide bushings according to drawings, samples, and working conditions. We can produce both standard and non-standard carbide bushings for pumps, valves, mechanical seals, rotating equipment, tooling systems, and abrasive service applications.

Custom options include carbide grade selection, inner diameter, outer diameter, length, wall thickness, oil grooves, lubrication holes, slots, steps, chamfers, sealing surfaces, tolerance, concentricity, and surface finish.

For an accurate quotation, please provide the drawing or sample, mating shaft dimensions, working medium, temperature, pressure, rotational speed, required quantity, tolerance requirements, and any special inspection or assembly conditions.
