Control Gear/Actuators

The landing flaps on the wings of an airplane serve to increase the air resistance during start and landing. The suited lubricant has to meet high demands, in order to ensure a smooth running control of the landing flaps. Very good friction and wear protection, a wide temperature range and excellent oxidation stability are prerequisites that the lubricant has to meet. LUBCON offers thixotropic high-grade lubricants that are successfully used by well-known aircraft manufacturers. For example, Turmogrease Li AzR meets SAE AMS 3057 specifications and can be successfully applied in rotary actuator gearboxes.

Landing Flaps - SAE AMS 3057

Turmogrease Li AzR

This product has been developed especially for the lubrication of wing control gears in the Airbus aircraft fleet. The semi-fluid meets all demands corresponding to SAE AMS 3057 and has been tested and approved by Liebherr Aerospace. Turmogrease Li AzR is miscible in any proportion with greases that apply to SAE AMS 3057 and ZF B831.

Elevator Actuator

Ultratherm LS 1002

This unique lubricant was developed on a basis of perfluorinated oils (PFPE) and special lithium soap. Under thermal or mechanical load, the lubricant flows back to the contact area and thus reduces wear to a minimum. In aerospace the product is used for special applications, e. g. the actuator of the pitch elevator.


Ultratherm 1000

The lubricating and sealing grease can be used in high vacuum applications up to 10-8 mbar. In aerospace, the lubricant is successfully used for the lubrication of bearings in asynchronous electric motor. The product has a high oxidation stability and can be applied in a temperature range from -70 °C (-94 °F) (-94 °F) up to 240 °C (464 °F).

Background information:

SAE International is an association of technical professionals and a global standard organization. The main focus is placed on on transport industries including automotive, aerospace, and commercial vehicles. Among other things, engineering professionals of all fields are working on the development of technical standards.

Lubricants for aerospace applications are specified in the aerospace materials specifications (AMS). For example, SAE AMS 3057 describes standards for the application of lubricants in aircraft gearboxes. This specific norm has become international standard and is referenced in maintenance manuals of OEM, aircraft manufacturers and airlines.
