Grease for gyroscopes

Description

On the basis of PES fluids created and produced a number of instrumental support, damping, balancing fluids gyroscopic instruments. The specified parameters of density and viscosity of these liquids provide a hydrostatic bearings float unloading girouzla (creation of neutral buoyancy), the accuracy of the gyroscope output signal and the effective damping girouzla and protection against shock and vibration. High stability properties and chemical inertness of these fluids made it possible to guarantee their performance in devices for long periods (over 20 years).
