SEIVIO Lovolub V129 special grease for optical adjustment mountsIt is a linear perfluoropolyether oil with extremely low friction coefficient.,Ultra-fine nanoscaleIt is made of thickened PTFE and refined with special anti-corrosion additives. It is specially customized for core adjustment mechanisms such as ultra-fine thread pairs and dovetail guide rails of precision optical adjustment mounts. Its core function is to achieve low-friction and smooth adjustment while preventing grease volatilization and migration from contaminating optical lenses, and maintaining micron-level adjustment accuracy and operation for a long time.TorqueStability.
