Custom Engineered Bellows

BellowsTech employs experts in the field of edge welded metal bellows. This expertise coupled with our precision products allows us to serve almost every industry and solve any application challenge.

Some common edge welded bellows applications are:

• Feed Throughs
• Actuators
• Implantable Devices
  
  

Specific to the Vacuum industry, some of our applications have helped ignite new approaches for other markets with various needs. Our Vacuum applications include:

Valve Stem Seal – The bellows, is used to seal a shaft hermetically while allowing axial shaft movement.

Feedthrough – the bellows acts as a flexible seal, allowing movement of a tool within a sealed environment. Linear and angular motion for “wobble stick” applications is available.

Rotary Feedthrough – The bellows are used within a bearing housing to translate rotation from an input shaft to a co-linear output shaft while sealing hermetically, eliminating the need for a dynamic seal.

Torque Coupling – The bellows are used for precise transmission of rotary motion.

Expansion Joint - The bellows allows for the expansion or contraction between two fixed bodies while maintaining a hermetic seal.

Actuator – The bellows acts as a piston converting pressure to linear motion eliminating the need for a dynamic seal.

Vibration Damper – The bellows are used to isolate vibration from one end of the bellows to the other while sealing hermetically.
