Marsh Brothers Aviation AeroLas™-Grey is designed for high pressure applications either as an interference fit bushing in applications requiring up to 30 MPa (4351 psi) compressive strength, or as a metal-backed bushing, which is able to withstand high bearing pressures.


  • Self-lubricating
  • Very good dry-run performance
  • Moderately abrasion resistant (lower abrasion resistance than AeroLas™-Black or AeroLas™-White)
  • High resistance to shock loading and vibration
