Royco 555 Turbine Oil 1 Gallon Lenco / Lencodrive Oil on 2040-parts.com
Orlando, Florida, United States
Description:
ROYCO 555 is an advanced 5 centistoke synthetic lubricating oil for gas turbine engines and helicopter
transmissions. The product is a blend of "hindered" polyol esters and a finely balanced modern technology
additive package resulting in enhanced load carrying performance, Antiwear, corrosion protection, and
excellent thermal - oxidative stability. Applications:
ROYCO 555 was specifically developed for use in high performance gas turbine engines developed during the
mid 1960’s for the SST and Concorde. These advanced engines required a lubricant having good high
temperature stability as well as extreme pressure load carrying capability. ROYCO 555 was developed for the
demands of increasingly higher power output engines that subsequently develop higher operating
temperatures and loads. It was also designed to give enhanced performance in current engines. ROYCO 555 was also formulated to meet the requirements of helicopter gearbox and transmission systems.
A high load carrying oil such as ROYCO 555 is necessary to meet the load requirements and reliability
demands of those systems. More recently with the need to transmit more power and higher loads through
helicopter gearbox and transmission systems, extensive evaluation by helicopter airframe manufacturers has
demonstrated this improved load carrying ability which has resulted in improved performance - particularly by
increased time between overhaul (TBO.) This oil should only be used in applications where synthetic oils
have been specified or in systems expressly designed for synthetic lubricants. ROYCO 555 should not be used with silicone-based elastomer. Approvals and Specifications: ROYCO 555 meets all the requirements and is qualified under U.S. Military specification: DOD-PRF--85734A
as well as: ▪ U.K. DERD.2497 ▪ XAS-2354 ▪ British DEF STAN 91-100 ▪ NATO Code O-160 ▪ UK Joint
Service Designation OX-26. ROYCO 555 is approved commercially for use in aircraft transmissions, gearboxes, and gas turbine engines
manufactured by Pratt & Whitney (521C Type II), Pratt & Whitney Canada, IAE, CFM International, General
Electric (D-50 TF 1), RR Allison (EMS-53 (Obsolete)) , Rolls Royce, Garrett, Motorlet, and Turbomeca, as well
as Garrett and Sunstrand accessories. ROYCO 555 is also approved for use in Eurocopter/Aerospatiale, Boeing Vertol, Bell Helicopter Textron,
Agusta, Hughes/McDonnell Douglas, MBB, Sikorsky, and Westland helicopter transmissions. |
