Gas foil bearing

Gas foil bearings allow for low friction and high-speed rotations by generating a pressurized gas film separating the rotating and stationary surfaces. When the shaft spins fast enough, gas between the shaft and foil is pressurized, pushing the foil and shaft away from each other to ensure contactless operation.

Since gas foil bearings use no oil, water, or lubricants, they weigh less and can withstand higher temperatures than other bearings. This makes them highly suitable for applications sensitive to contamination and corrosion.

Bosch delivers high-quality, state-of-the-art gas foil bearings that have been developed to meet automotive standards. Highly suitable for contactless, oil-free, high-speed, and low-maintenance applications such as fuel cell-electric air compressors, blowers, expanders, and heating, ventilation, and air conditioning systems.
