1. Although all versions of the RB26DETT N1 engine use Journal Bearing T25 Turbochargers. 2. Without adequate lubrication, journal bearings would fail due to the excessive heat caused by friction. 3. MORGOIL Bearings are totally enclosed, precision journal bearings that operate on a hydrodynamically generated film of oil. 4. De Laval's turbine used mechanically lubricated journal bearings which weren't insulated from the inside of the turbine. 5. The disadvantage of this design is its lower load carrying capacity, as compared to typical journal bearings. 6. "A hot journal bearing, " he announced authoritatively, " smells completely different than a hot motor bearing ." 7. Journal bearings are lubricated with fluid. 8. These were called " journal bearings " and relied on the lubricant to form a " fluid bearing ". 9. This helps attenuate resonances at the gyroscopic frequencies of journal bearings ( sometimes called conical or rocking modes ). 10. As an auxiliary function, the jacking gear also helps to maintain a protective oil membrane at all shaft journal bearings.
