Vacuum technology - Vacuum bearings

In close cooperation with industrial partners, GMN develops overall concepts for complex bearing systems. Especially here these are called vacuum bearings for turbo molecular pumps (TMP).

Challenge against vacuum bearings for turbo molecular pumps:

Optimized engineering

For turbo molecular pumps GMN develops custom made high precision ball bearings (vacuum bearings) with special dimensions, designs and cages.

Important performance criteria:

• Product-optimized bearing design
• Use of shielded bearings for protection from contamination and to increase life
• Ceramic balls for higher speeds, minimum friction and optimized bearing dynamics
• Total tribology concept (lubrication, preservation, surface quality, materials)
• For grease lubrication, use of the TXM cage for low-vibration, low-noise running
