Moldable/Machinable Liners

Machinable/Moldable LinersKaman Specialty Bearings' KAron liners are a combination of thermosetting resin and filler materials in particle or fiber form. Our liners differ significantly from other self-lubricating materials in that there are no continuous interconnecting fibers or weave that can provide a moisture path to the bonding substrate. A moisture path can promote corrosion under the liner or significant liner swelling when used in a moisture-laden environment.

Liner materials used in our bearings include:

  • KAron - Temperatures to 450°F (232°C)
  • KAtherm – Temperatures to 500°F (260°C)
  • KAcarb – Temperatures to 1200°F (635°C)

Characteristics considered in the formulation of our self-lubricating liners include load carrying capability, operating temperature, coefficient of friction, sliding/rubbing velocities or any combination.

In addition to typical bearing applications, a KAron liner has other valuable uses including:

  • Salvaging Components – KAron can be applied in various thicknesses providing a method of salvaging components with oversize bores, undersize OD’s, worn or damaged surfaces, etc.Such applications can be rapidly addressed by a Kamatics representative as to the suitability of Karon as a solution.
  • Fretting Protection – KAron can be used as an inexpensive barrier to eliminate/prevent damaging contact between expensive components. In many cases, KAron can be used as “applied” without any subsequent machining
  • Corrosion Protection – KAron has demonstrated limited protection against corrosion while providing a bearing material that can be machined to very close tolerances
