 Vapor lock o-ring prevents air being pulled into hot stationary gearbox while it is
cooling
 O-ring lifts off metal at speeds > 1m/s (200ft/min)
 Vapor lock designs without the o-ring are available as well
 Competitors use fully contacting seals that MUST be replaced. Some use
 PTFE , or
 2 o-rings
 Either way their products will fail because of contact

Contamination Chamber and Expulsion Port
To Maintain a Clean Gearbox Environment
 Bore side oil return port
2010
 Expulsion port for debris stopped
by the bearing isolator
 Contamination chamber for dirt,
debris and other contaminants that
would have otherwise reduced
gearbox life if not isolated
 Centrifugal forces expel debris
when the system is in motion
 Gravity takes over when the
system is stationary

 This bore side o-ring is
sheered in installation
thereby perfectly sealing
any pre-existing gaps
