Spadone Self Lubricated Bearings (Met 90) Solves Bearing Problems in hostile environments​​​​​​
For The Extremes

  • High Temperatures | Conventional lubricants would carbonize. Such applications are in furnaces, dryers, ovens, kilns, dust collectors, hot conveyors, and louvers​​
  • Exteme Cold | in Cryogenics
  • Dry Environments | Where contamination is undeirable. Textile, food, drug production, pollution control, printing
  • Wet applications | From high humidity to toal submersion. pumps, meters, textile finishing, chemical processing, plating equipment
  • Inaccessible location | difficult or unable to reach graphite works as the lubricant
We use a solid lubricant which, when introduced between unlubricated surfaces, acts as a smoothing agent - filling pores and imperfections in the metal surface and coating them with a thin layer of lubricant. ​​

Our plugs expand and impregnate bearing surfaces with a hard, mirror-like film. Turning or sliding during machine operation spreads the lubrication to greatly reduce friction and wear.


Using a graphite compound in either plug or paste form, the lubrication is press fit into drilled recesses. The recesses are arranged into  an overlapping, staggered pattern to provide a greater degree of lubrication than can be obtained by any other oiless lubrivation method.​​

Our bearings are self lubricating and never require oil or grease. For normal duty, they are manufactured from a variety of bronze alloys; including tin, leaded, manganese, and aluminum bronze alloys. However, they can be made from almost any metal when the application demands it.
