CHF SSUCF series stainless steel-cast iron composite mounted bearings are innovative products developed for moderately corrosive environments that require a balance between the corrosion resistance of stainless steel and the structural strength of cast iron. This series features a unique stainless steel-cast iron composite design, using stainless steel in critical contact areas and high-strength cast iron in the main structure. It provides European and American industrial customers with cost-effective and reliable mounted bearing solutions, particularly suitable for applications requiring a certain level of corrosion resistance but with tight budgets, such as food processing auxiliary equipment, agricultural machinery, and general industrial conveying systems.
Key Technical Features
Stainless Steel in Key Components: Bushings and sealing contact surfaces are made of AISI 304 stainless steel, providing critical corrosion protection.
Cast Iron Main Structure: The base is made of HT250 high-strength gray cast iron, ensuring structural strength and stability.
Optimized Cost Structure: Compared to all-stainless steel products, costs are reduced by 30-40%, while maintaining over 85% performance retention.
Modular Design: Stainless steel components can be replaced individually, extending overall service life.
Enhanced Sealing System:
Double Lip Contact Seal: The main seal uses NBR nitrile rubber, with a temperature range of -30°C to +100°C.
Stainless Steel Dust Cover: A removable 304 stainless steel dust cover provides additional physical protection.
Labyrinth Splash Protection Design: Combines axial labyrinth design to prevent direct liquid impact.
Standard Protection Rating: IP55 protection rating meets the needs of most industrial environments.
