Bushings and Frictional Bearings


Open and Ground Tolerances

Hyperion manufactures high quality cemented carbide bushings and bearing sleeves that work in corrosive and abrasive (due to load, rotation, friction, etc.) environments. Our carbide bushings show wear and corrosion resistance with a high fracture toughness for demanding axial thrust. Hyperion also offers FDA compliant cemented carbides.



• Bushings

• Frictional bearings

• Materials compliant with FDA, EC 1935/2004, and USP 87 requirements

• Shape features as chamfers, radii, slots, holes, and key-way

• Inner and outside profiles

• Laser engraving

• Polished finish


• Excellent cemented carbide performance in water/food applications with alloyed binder grade range

• Easy to assemble and resistant to handling

• Reliable and consistent material thanks to the more than 60 years’ experience of developing cemented carbide grades
