SEIVIOVaculub F450 Vacuum Motor Bearing GreaseYesMade of high-purity linear perfluoropolyether oil, nano-level ultra-finePTFE thickens. It is refined by adding special anti-corrosion additives. It is a special lubricating material specially customized for motor bearings operating at high speeds in vacuum/ultra-high vacuum environments. It avoids volatilization and gas production through extremely low saturated vapor pressure design, while taking into account the core requirements of high-speed wear reduction and high-temperature stability of motor bearings, and solves the problem of ordinary lubricating grease evaporating and failing in vacuum environments and contaminating the cavity.
