  • Stainless Steel Back (SS304, SS316)
  • Sprayed PTFE Lubricating Layer
Key Characteristics
  • High corrosion resistance for demanding environments
  • Superior wear resistance and durability
  • Ideal for strong acid, strong alkali applications with light loads and medium to low speeds
  • Wear resistance significantly exceeds monolithic PTFE bearings and graphite bearings
Product Availability
  • Standard cylindrical stainless steel bushings
  • Flanged stainless steel bushings
  • Thrust washers and strips
  • Custom designs available with short lead times
  • Lead-free options also available
Industrial Applications
PVB012 stainless steel bushing bearings are widely used in pumps, ball valves, marine industry equipment, food processing machinery, and chemical acid-base flowmeters.
