SF-1S flanged bush



Premium SF-1S flanged bush: Engineered for Corrosive & High-Precision Environments

Maximize the operational reliability of your pivoting and rotating assemblies with our SF-1S Stainless Steel Backed Flanged Bushings. In industries where hygiene and chemical resistance are non-negotiable, standard carbon steel or bronze-based bearings often fall short due to oxidation and frequent maintenance needs. Our multi-layered, precision-engineeredSF-1Sseries eliminates these vulnerabilities by integrating a high-grade stainless steel backing with a self-lubricating PTFE interface, ensuring peak performance in the most punishing conditions.

Why Choose SF-1S flanged bush?

The primary advantage of ourSF-1Sseries lies in its Material Synergism and Flanged Geometry. Unlike standard bearings, our flanged design handles both radial and axial loads simultaneously while providing the following benefits:

  • Maintenance-Free Dry Operation: The PTFE/Fibre mixture is engineered for dry running, offering a low coefficient of friction and superior sliding characteristics without the need for external grease.
  • Total Corrosion Immunity: Utilizing SUS304, 316, or 440 stainless steel, these bushings are oil-resistant, acid-resistant, and seawater-resistant, outperforming standard alloys in caustic environments.
  • Surface Protection Technology: During operation, a transfer film is created that coats the mating metal surface, forming an oxide-type solid lubricant film to prevent wear on expensive shafts.

Advanced Multi-Layer Engineering

OurSF-1Sbushings are manufactured using a sophisticated sintering process to ensure structural integrity and thermal efficiency:

  1. PTFE/Fibre Overlay (0.01~0.03mm): A lead-free surface layer that provides excellent initial transfer and dry-lubrication.
  2. Sintered Bronze Interlayer (0.20~0.35mm): Acts as a high-strength reservoir for the PTFE mixture while providing maximum thermal conductivity away from the bearing surface.
  3. Stainless Steel Backing (SUS304, 316, 440): Provides the rigid foundation necessary for strong acid and alkali situations and high-impact resistance.

Typical Applications

SF-1S flanged bushings are the standard for high-cleanliness and high-corrosion sectors:

  • Food & Pharmaceutical Machinery: Lead-free composition makes it ideal for direct contact or sensitive processing environments.
  • Chemical & Pumping Industry: Exceptional performance in alkali flow meters, pumps, and chemical engineering machinery.
  • Marine & Ocean Engineering: Resists the corrosive effects of seawater in valve and shipboard components.
  • High-Cycle Industrial Equipment: Used in printing machines and motion elements where maintenance access is limited.
