Marsh Brothers Aviation AeroLas™-Black is a general-purpose self-lubricating polymer offering good performance as an interference fit bushing in applications requiring low friction, wear resistant performance in applications requiring up to 12 MPa (1740 psi) compressive strength.

When bonded to a metal substrate and machined to its optimal thickness, AeroLas™-Black offers superior compressive strength in self-lubricating metal-backed bushing applications.


  • Long life with low dry coefficient of friction
  • Good abrasion resistance
  • Low coefficient of friction (typically 0.20-0.25)
  • High resistance to abrasion in dry applications
  • High resistance to shock loading and vibration

Typical Applications

  • High-strength composite bushing liner, bonded to metal housing and machined back
