Bushing
Sun will revolves around itself, with vibrations as in the Pic 1
1 Front Bushing = Mercury
It helps to reduce vibration and stabilize the main axis, the sun (Absorbs Perpendicular Vibration), (1.1 of The Rotation's Output Rule - Less Output ), (Pic 2)
2. Back Bushing = Uranus
It helps to reduce vibration and stabilize the main axis, Jupiter (Absorbs Horizontal Vibration) (1.1 of The Rotation's Output Rule - Less Output), (Pic 3)
