Bushings & Bearing Sleeves

Hyperion’s tungsten carbide bushings and carbide bearing sleeves are engineered to deliver reliable performance in corrosive and abrasive operating conditions. Developed from proprietary cemented carbide grades, they combine high hardness with fracture toughness to support demanding axial thrust and hydrodynamic bearing applications.

• Excellent wear and corrosion resistance in fluid‑handling environments
• Suitable for water, food, and chemical applications, including FDA‑compliant grades
• High mechanical strength for stable, long‑term performance
• Consistent material quality backed by more than 60 years of carbide grade development

Hyperion supplies precision‑engineered solutions for a wide range of fluid‑handling systems, including:

• Carbide bushings: Cylindrical wear components that support rotating shafts while maintaining tight clearances in abrasive or corrosive fluid-handling environments.
• Tungsten carbide bearing sleeves and hydrodynamic pump bearings: Carbide components designed for rotating equipment operating with controlled contact or fluid-film lubrication, helping reduce wear, maintain geometry stability, and extend service life in demanding pump and compressor applications.

These components are commonly used in pumps, compressors, flow meters, centrifuges, and other rotating or sliding assemblies where dimensional stability and wear resistance directly impact uptime and maintenance intervals.

Materials & Shapes

Hyperion offers extensive customization to match functional, assembly, and regulatory requirements:

• Cemented carbide materials compliant with FDA, EC 1935/2004, and USP 87
• Inner and outer profiles, including stepped and contoured geometries
• Chamfers, radii, slots, holes, and key‑ways
• Polished surface finishes
• Laser engraving for part identification and traceability

Technical Details

• Outer diameter: 3 to 350 mm
• Height: 1.5 to 300 mm
• Wall thickness: > 0.10 mm

Bushings & Sleeves Carbide Grades

Hyperion offers a broad portfolio of cemented carbide grades optimized for fluid‑handling wear applications:

• Hardness range (HV30): 900 to 2200
• Grades engineered for corrosion resistance down to pH > 2
• Alloyed binder systems for improved performance in corrosive media

Material selection is guided by application‑specific requirements such as load, speed, media, temperature, and surface finish.

Tolerances & Finishing Options

For applications requiring tighter dimensional control, carbide bushings and sleeves can be precision‑ground to micron‑level tolerances:

• Ground tolerances to µm level
• Inner and outer diameter grinding
• Polished finishes with Ra from 0.025 to 0.2–0.5 µm
• Laser engraving available

Customized packaging options include plastic trays, thermo‑ or vacuum‑sealed packaging, and bubble envelopes. Additional sizes, tolerances, carbide grades, and small‑quantity test batches are available upon request.
