Product Description
Silicon carbide sleeves protect shafts and provide hard sliding or wear-contact surfaces in pumps and process equipment.
A shaft sleeve shields the shaft from the process medium or a wearing interface; a bushing supports relative sliding between paired surfaces. Straight, stepped and flanged forms connect these functions to the surrounding pump or machine assembly.
Silicon carbide combines hardness, wear resistance and corrosion resistance for many abrasive or chemically demanding duties.
Product Features
- Hard wear surfaces for shaft and bushing interfaces
- Corrosion resistance for compatible process fluids
- Thermal conductivity to transfer heat from the contact region
- Low thermal expansion for dimensional stability
- Straight, stepped and flanged sleeve configurations
Typical Applications
- Shaft-protection sleeves in process pumps
- Sliding bushings in pumps and rotating equipment
- Cylindrical wear liners for abrasive process assemblies
- Protective interfaces exposed to compatible corrosive fluids
