Military Helicopter Bearings
Combat helicopters are vulnerable to sudden loss of transmission lubrication due to enemy fire. Increasing the transmission life after sudden lubrication loss increases the probability of finding a suitable emergency landing site and directly saves lives.
The performance of standard bearings and standard bearings with DICRONITE® dry lubrication was compared under sudden lubrication loss conditions.
Under lubrication loss conditions, standard bearings failed at a maximum time of 6 minutes, minimum time of 3 minutes.
A DICRONITE® lubricated bearing ran for the duration of the test (38 minutes), under lubrication loss conditions, a six fold increase. DICRONITE® increased bearing life sufficiently to enable an emergency landing per the military’s test conditions.
