Satellites
Lubricants play a key role in preventing friction and wear of satellite components such as reaction wheels, scan mirror assemblies, camera optics, and other components that require angular or precision contact bearings. Nye has been working with leaders in the space industry for over 65 years and launched our lubricants for the first time in a satellite 27 years ago.
Our aerospace lubricants are designed for components that require low outgassing, low particle generation and extreme temperature performance. These lubricants are also what we like to call ‘Lube for Life’ meaning that they have long-life performance to ensure reliability and mission success for the entirety of both long and short-term missions.
This system is responsible for positioning the solar panels in order to harvest sun light that can be turned into energy. MAC lubricants fortified with both antioxidants and anti-wear additives will help ensure long life of components.
Harmonic Gear Drive - Rheolube® 2004 & Synthetic Oil 2001-3PB
Slip Ring in Power Transfer Assemblies - Rheolube® 2001
This system moves in a horizontal motion to scan targeted areas for imaging. Lubricating the bearings within the assembly will reduce vibration, and allow the system to move in a quick, smooth motion.
Bearings - Synthetic Oil 2001-3PBNP
By providing attitude control, reaction wheels are the control gyros for satellites. A medium viscosity MAC grease will operate through high-torque adjustments and can withstand extreme temperatures.
Barrier Film - NyeBar® Type-P
Bearings - Rheolube® 2000
This instrument supports and spins the satellite throughout the mission. The bearings within the assembly are in constant rotation and require a MAC grease fortified for friction reduction.
Angular Contact Bearings - Rheolube® 2000 & Synthetic Oil 2001
To ensure contaminants from other lubricants do not creep onto the camera lens, NyeBar® can be applied to multiple mechanisms on the camera mast. NyeBar® creates a barrier film, holding the lubricating oil in place. Ultrafiltered MAC lubricants have low outgassing rates and superior anti-wear performance, making them ideal for components within or near a satellite camera. Lubricants with a lower particle generation count will ensure that optical components are not compromised.
