Bearing sleeve products and bushings for aircraft landing gear operation in Pfinodal® C72900 alloy

Landing Gear Bushings

Landing Gear Bushings

Aircraft applications demand bushings and bearings that deliver outstanding durability, to ensure consistent performance despite changes in temperature and air pressure. We have led the industry in the production of Pfinodal® (C72900) with superior bearing properties for aircraft landing gear material. Our production processes and heat treatments combine to ensure the high hardness required in a bearing material for aircraft bearing sleeves, and bushings for landing gear.
Products
We offer Pfinodal® (UNS C72900) that delivers superior mechanical and physical properties in comparison to conventional high-performance alloys. The material has been in use for more than 20 years under patent numbers 5527113 and 5552106 for rock bit bearing applications before the aerospace industry also moved towards these bushing sleeve materials for their anti-galling, low friction and high hardness characteristics.
Advantages
Our highly specialized Pfinodal® (UNS C72900) material is manufactured through wrought powder metallurgy to deliver exceptional properties for landing gear bushings and aircraft bearing sleeves.
  • Anti-galling, low friction and high hardness characteristics
  • Superior durability and strength for extended product life
  • Non-magnetic properties required in bushing sleeves and bearing material
  • Safe alternative to Beryllium Copper with similar mechanical properties
Applications
AMETEK SMP has offered turnkey bearing products for the oil and gas industry for decades and can offer the same level of high quality finished products for aerospace applications, specifically in landing gear operation. Alternatively, we offer unfinished bar and near net shape tube products off-the-shelf as machining bar.
