Vacuum motor bearing grease

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.

• It can still maintain a complete oil film under operating conditions above 3000 rpm, inhibiting bearing fretting wear;
• Extreme pressure performance reaches 4-ball welding load ≥2800N;
• Has good high temperature stability and vacuum stability;
• Suitable for medium and high-speed motor rolling bearings operating under severe high temperatures or wide temperature ranges;
• It has extremely high chemical stability and does not react with acids, alkalis and highly reactive substances.

Suitable for semiconductor and aerospace fields: vacuum environment motor bearings for space simulation test chambers, satellite attitude control mechanisms, vacuum coating machine motors, motors in semiconductor vacuum chambers, molecular pump motors, aerospace vacuum motors, electron beam equipment, internal rotating motor bearings of mass spectrometers, etc.
