Primary Applications
These bellows are critical in advanced vacuum systems where large movements must be sealed:
-
Particle Accelerators & Synchrotron Light Sources:
-
Use: Connecting extremely long beamline vacuum chambers to compensate for thermal expansion and seismic or settlement-induced displacements.
-
-
Semiconductor Fabrication Equipment:
-
Use: Interfacing between wafer transfer chambers, process modules, and load locks. They compensate for thermal drift and alignment tolerances, ensuring precise robotic wafer handling while maintaining UHV conditions.
-
-
Vacuum Furnaces & Metallurgy:
-
Use: Connecting furnace sections or the furnace to feeding mechanisms. They absorb the massive thermal expansion during heating/cooling cycles, preventing structural stress.
-
-
Large Space Simulation Chambers:
-
Use:Â Providing a flexible, sealed connection between massive vacuum chambers and their pumping systems or auxiliary ports, accommodating structural flex and vibration.
-
-
Precision Analytical Instruments:
-
Use: In systems like electron microscopes (TEM/SEM) or mass spectrometers, allowing for adjustable positioning of stages, apertures, or sample introductions without breaking vacuum.
-
-
Vacuum Robotic Actuators:
-
Use: Serving as a flexible “wrist” or translation seal for robotic arms inside vacuum, allowing extensive movement while maintaining the pressure barrier between the atmosphere (at the drive end) and the vacuum.
-
-
Vibration Isolation & Special Connections:
-
Use: Decoupling two pieces of equipment (e.g., a sensitive analyzer from a noisy pump) to dampen vibration transfer. Also used to connect two large, independently supported vacuum vessels that may shift relative to each other.
